How to detect potato pests: photo, description and treatment, useful tips for experienced and novice gardeners. Who eats potatoes in the ground, gnaws straight, and how to deal with it

Various pests can harm potatoes. Each of them must be dealt with in specific ways. To prevent their development, preventive measures should be taken in advance.

Common potato pests

The Colorado potato beetle is the most common and dangerous potato pest. It is gluttonous and brings tangible damage to the crop. In addition, adults are able to fly, so they can travel long distances and infect many plantings.

The Colorado potato beetle is a member of the leaf beetle family. This pest has an oval body, the length of which varies between 8-15 mm, and the width is 7 mm. The belly is orange with black spots. Rigid elytra adjoin the body of the pest. This beetle has three pairs of legs.

Both larvae and adults of the pest feed on the leaves of cultivated and wild nightshade plants. In addition to potatoes, they eat the leaves of tomatoes and eggplants, bell peppers.

Adults hibernate in the soil, at a depth of about 50 cm. After wintering, they go outside, begin to feed and mate.

Females lay their eggs on the underside of potato leaves. During the season, one female Colorado potato beetle lays about 350 eggs. The eggs hatch into larvae. This happens 1-2 weeks after laying. Everything depends on weather conditions.

Larvae, like adult beetles, eat potato leaves, leaving only the stems. Having destroyed the tops of one plant, the pests move to another.

The life expectancy of this pest is 1 year, but some individuals live up to 2-3 years.

Birds that destroy insects are not able to fight this pest. This is due to the fact that many toxic alkaloids accumulate in the bodies of Colorado beetles - this makes them inedible.

These pests are capable of destroying the entire potato crop, as they are very voracious. Colorado beetles can absorb not only young stems, but also ripened tubers.

caterpillars

Potatoes can also be harmed by caterpillars. This is a potato owl. The caterpillars of this butterfly prefer moist soil as well as shaded areas. The caterpillar appears on the potato stalk in late April - early June.

Owls are predominantly nocturnal. Caterpillars belong to the group of polyphagous pests: they eat not only potatoes, but also carrots, onions, and some other crops.

The caterpillars of the potato scoop cause the greatest harm in rainy years, at moderate air temperatures.

The potato scoop has a light yellow or bright red color, its head is red, without a pattern. The body length is about 5 cm. It has 8 pairs of legs. The caterpillar infects the area above the root neck. The plant on which the scoop settled quickly dries up and fades.

Caterpillars penetrate inside the potato tuber, gnawing through the stem of the bush. Thus, the whole plant suffers.

Caterpillars usually do not damage the skin of potatoes. They make a small hole and a passage, at the end of which they form at first a small, but constantly increasing cavity, which is gradually filled with excrement. When the scoop finishes feeding, it leaves the tuber, making a new, wider move. Caterpillar-damaged potatoes usually rot due to secondary infection.

Medvedka is a straight-winged insect whose body reaches up to 5 cm in length. The body is large, dark brown. Medvedka has short wings and powerful paws, with which it can burrow deep into the ground. This insect also has strong jaws and long whiskers.

An adult bear makes a nest not too deep underground, which it fills with eggs. After laying, hundreds of larvae 2-3 mm in size are hatched. They grow for several years, after which they begin to lead a full-fledged lifestyle.

Medvedka is a danger to all plants that are found on her way. It harms not only potatoes, but also cucumbers, beets, cabbage, cereals.

The insect has a spindle-shaped abdomen and a head with big eyes. Around the gnawing mouth are two pairs of tentacles. The insect breeds in the ground, laying up to 250 eggs at a depth of 15 cm or more.

The danger to potatoes is not only adult bears, but also their larvae. They gnaw through the stem, which causes it to fall or dry out, ceasing to develop. Medvedka is also able to gnaw through large cavities in tubers.

Most often, the bear completely eats away root crops. Even those potatoes that were simply “eaten up” by a bear are unsuitable for food.

The wireworm is a pest whose danger is comparable to that of the Colorado potato beetle. It belongs to the beetle family. Its body length reaches 7-20 mm.

Outwardly, the wireworms are the larvae of the click beetle with a finger-like process directed backwards.

The adult is a black beetle with an elongated body.

One female is capable of laying up to 150 eggs. The larvae hatch after 20-40 days. They grow and develop within 3-4 years.

In the first year, the larvae do not pose a danger to cultivated plants, but in the next 3 years they become active and are able to eat the seeds even before shoots appear from them.

Wireworms inflict great harm potatoes. They destroy seeds and seedlings, gnaw roots and stems, penetrate into root crops and tubers. Because of this, the potatoes begin to rot.

Wireworms actively eat potatoes if the weather is hot, there is not enough moisture, and also if they lack couch grass roots, which are the favorite food of this pest.

The golden potato nematode is a microscopic pest that is the causative agent of the disease globerosis.

The nematode lives in the soil, remaining active for up to 10 years. The pest survives the winter as larvae and eggs in cysts.

IN spring period the eggs develop into larvae that penetrate the roots of the plant. Here they develop until they turn into sexually mature females and males.

The females break the roots, partially remaining inside the plant. After fertilization, they lay their eggs inside their own body. When the eggs mature, the body of the female dies, and the eggs are stored inside it. When harvesting potatoes, the cysts fall off and penetrate the soil. The cycle of development is repeated.

Nematode under the microscope

Potato flea in adulthood is a beetle up to 3 mm long. The main color is black, the limbs have a dark brown tint.

The flea damages potato tops. Larvae developing on the roots can cause the loss of healthy bushes. If present optimal conditions for the development of the pest, then a significant part of the crop deteriorates.

Potato fleas leave pits and holes on the surface of the leaves. The adults eat the leaves. If she was severely affected, then potato seedlings die, especially if the planting was late.

The larvae of the potato flea inhabit the root system of various nightshade plants: not only potatoes, but also tomatoes, eggplants.

The potato flea causes the greatest harm to bushes if it is a warm and humid year.

This pest is a carrier of many infectious potato diseases.

This butterfly is capable of destroying up to 80% of the crop. It has a small size, which reaches 6-8 mm in length. In the summer, the development process from egg to adult takes up to 4 weeks.

Potato moth is unpretentious to external conditions. The butterfly lays its eggs on the underside of the leaves of the plant. The clutch usually consists of 1-20 eggs. The eggs hatch into caterpillars, which later turn into butterflies.

The potato moth feeds on the underside of the potato leaf. When the tops dry out, the pest moves to the tubers. Through the eyes and cracks on their surface, the moth penetrates and feeds on the pulp.

Potato moth weakens potato bushes, damages tubers and reduces the quality and quantity of seed.

This pest belongs to the order Hemiptera. This small insects, their body length reaches 3.5 mm. Among them there are both winged and wingless individuals. The pest is found everywhere.

The body is shiny, has the shape of an ellipse, the color is from white-green to yellow-green.

oral apparatus in these insects it is adapted for piercing tissues and sucking juice from plants. Because of this, the damaged potato leaves dry, the crop stops growing, and the yield decreases.

Feature of these pests lies in the fact that they leave sugary secretions in the places from which they absorbed the juices. These secretions attract other pests, creating favorable conditions for the development of fungi. In this case, the culture completely dies due to the invasion of various insects.

Aphids reproduce very quickly in dry, warm weather. The number of aphids is significantly reduced if the site has ladybug.

Chafer

May beetle larvae are also capable of damaging the potato crop.

The Maybug appears in late April - early May. One female lays up to 70 eggs in the ground. After a few weeks, the larvae appear. In the first year, they feed on organic residues, enriching the soil with waste products and benefiting the soil. In subsequent years, the larvae develop a chewing apparatus, thanks to which they are able to eat the roots and tubers of potatoes.

The larvae are located in upper layers soil, at a depth of 20 to 40 cm.

With a high concentration of larvae in the soil, a large number of potatoes are destroyed. Even one larva at the age of 3-4 years can damage several dozen tubers in just a few weeks.

It is quite simple to determine that the potato was affected by the May beetle larva: if the leaves wither, dry and turn yellow for no apparent reason, then this is the result of the activation of this pest.

Naked slugs rarely attack potatoes, but can still be harmful.

The length of their body, depending on the species, can reach 3-6 cm. They are most active at night. For them, places with high humidity are most attractive.

Slugs infect the foliage and tubers of potatoes. They gnaw holes in the leaves irregular shape. They leave intact only the stem and the largest veins.

Crawling from one plant to another, slugs spread fungal and viral diseases. If they damage potatoes, late blight develops.

rodents

Certain types of rodents also pose a danger to potatoes. Often this culture is spoiled by a mole rat - an animal resembling a mole. Instead of eyes, he has a fold of skin covered with stiff bristles. It feeds only on root crops and does not eat insects. The mole rat eats large potatoes on the spot, drags small ones into a mink.

The earth rat also gnaws on potato tubers. It can be seen on land plots that are located next to water bodies. It penetrates 15-25 cm underground and gnaws at root crops. In addition to damage to the crop, the rodent violates the root system of plants, which leads to their drying and a decrease in yield.

The earth rat also creates pantries underground in which he hides food for the winter. The depth of such warehouses is about 20 cm. This rodent is very prolific and brings out many new pests in a short time.

leafhoppers

Cicadas are insects small size(1-3 cm), which are like jumping butterflies. During the day they live in anthills, and at night they go outside to drink the juice of plants.

Cicadas reproduce very quickly: only 20 days are enough for an adult to develop from an egg. Their wide distribution throughout Russia was facilitated by the import of plants from abroad.

By sucking the juice from the leaves of cultivated plants, leafhoppers damage them: this leads to a slowdown in development and stunting, as well as the death of part of the potato bush.

Potato leaves damaged by leafhoppers turn yellow and deform, white or red spots appear on their surface. Through the damaged areas, bacteria and fungi freely penetrate, causing the development various diseases.

Also, leafhoppers can act as carriers of viral diseases. These pests infect plants with poisonous saliva and lay eggs. Both adults and larvae pose a threat to plants.

Potato Pest Control Methods

When pests appear, you must immediately take measures to combat them, otherwise you can not only lose your crop, but also get potato tubers infected with diseases that pests carry.

Most effective methods that allow pest control are the following:

Chemical processing

Various preparations with chemical compounds are a reliable way to neutralize beetles and insects that harm potatoes:

To cope with the Colorado potato beetle, you should treat the area with Colorado, Sumicidin or Marshal.
To combat caterpillars, drugs Danadim, Zolon are used.
Drugs such as Medvetoks, Medvecid, Phenaskin Plus are effective against Medvedka.
The nematode that harms potatoes can be neutralized with chemicals that contain phosphamide or mercaptophos (Dimethoate, BI-58).
To neutralize the wireworm, use Force, Celeste Top, Voliam Flexy.
Potato scoops are sensitive to insecticides Tsimbush, Decis.
Rodenticides and fumigants are effective against rodents.
Potato moth is removed from the site with the same preparations that are used to combat the Colorado potato beetle. This pest also dies from Decis or Fastak. If potato moth wound up in the cellar with harvested, then the affected tubers can be treated with solutions of Lepidocide or Bitoxibacillin. You can also use FAS or Gamma smoke bombs.
If leafhoppers are wound up on the site, then the affected potato bushes must be treated with insecticides such as Proteus, Calypso, Biscay, Akarin.
Against potato aphids, insecticides such as Force, Thunder 2, Regent are used.

When using chemicals, you must follow the safety rules specified in the instructions in order to avoid harm to your own health.

Folk methods

To combat the Colorado potato beetle, you can use calendula: this plant has an odor that these pests cannot tolerate. You can plant it around a field where vegetables are planted.

You can also fight the Colorado potato beetle with the help of wormwood tincture. You need to take a third of a bucket of fresh wormwood, pour boiling water over it and insist. Treat the infected areas with the resulting infusion.

Many pests do not like the smell of garlic or onions. That is why the affected potato bushes can be treated with an infusion based on them. For cooking, you need to take 250 g of onion or garlic, chop, pour a liter of water. Infuse for a week in a closed container, then treat the bushes with the resulting composition.

They fight with a potato flea with a mixture that consists of ash, chamomile decoction and tobacco dust, taken in equal proportions.

You can effectively deal with the bear with the help of chicken manure: this pest does not live on fertilized soil. You need to take 2 kg of litter, dissolve in 10 liters of water. The resulting solution is again diluted at the rate of 1 part of the solution to 5 parts of water. With this composition, fertilize the areas of land infected with Medvedka.

Many pests do not tolerate the smell of plants with a pungent aroma. That is why parsley, mustard, lavender, peppermint, coriander, basil, fennel can be planted next to potato bushes.

soil care

To get rid of pests, it is imperative to dig up the soil in early autumn, thus bringing to the surface layers in which larvae and eggs can be located. During the summer period, you need to loosen the earth.

Preventive measures

To prevent the appearance of pests on potatoes, adequate measures must be taken in a timely manner.

To prevent the appearance of the Colorado potato beetle, you need:

plant potatoes next to garlic, beans, coriander - they interrupt the aroma of nightshade crops, which attracts the pest; if there are no such plants, then they should be planted along the perimeter of the area where potatoes are planted;
pour spruce or birch sawdust between the rows of potatoes - they emit a resinous smell that repels the beetle.

To prevent the appearance of a nematode, it is necessary:

treat the soil in which potatoes grew with urea: per 1 sq. m of land you need 1 kg of urea, it is covered and dug up;
burn an infected plant without shaking off the soil from it;
give preference to varieties that are resistant to this pest: these include Rosara, Zhukovsky, Symphony.

You can prevent the appearance of a wireworm in the following ways:

plant legumes next to potatoes - they repel this pest;
do not leave potatoes in the ground for the winter, even if they are spoiled;
dig deep in the garden in the fall;
remove weeds and carry them out of the garden.

To prevent the appearance of a bear should:

dig deep into the soil in autumn;
loosen the ground in spring and summer on a regular basis;
plant plants with a strong smell next to potatoes: coriander, marigolds;
when planting potatoes, water the wells with a solution of iodine (20 drops of iodine per 10 liters of water).

Watch a video about potato pests and measures to prevent their appearance:

There are many types of pests that spoil potatoes. You can fight them with the help of chemicals and folk remedies. To prevent the appearance of pests, you should take care of the soil, dig it up in the fall. Plants with a strong smell should be planted around the perimeter of the garden.

To get a high yield, you should know the main diseases and pests of potatoes in order to fight them in a timely and skillful manner. The most common potato pests: stem nematode, Colorado potato beetle, bear, wireworms, winter cutworm caterpillars, potato moth and many other "lovers" to eat root crops. Among the diseases can be identified: potato rot, macrosporiosis, potato cancer. Today we will talk about them and other dangerous potato pests.

The most dangerous potato pests

Wireworms and false wireworms

Pests of the larvae of the nutcracker beetle and darkling beetle, damaging the tubers and stalks of potatoes. Their body is dense, worm-like, yellow in color, about 20-25 mm long.

signs

They harm the fact that they gnaw through the tubers, making long, narrow channels in them. Such damage is a favorable environment for pathogens that cause rot. During the growth period, pests damage the root system, the base of the stems, so the plants are significantly behind in development or wither.

The fight against potato pests - wireworms and false wireworms is carried out with the help of regular crop rotation, using legumes.
Spring and autumn digging of the soil for the destruction of pest larvae.
Liming of acidic soils;
During spring and summer: loosening the soil, destroying weeds;

Colorado beetle

Beetles are dangerous pests of potatoes, destroying tops and tubers, which leads to a decrease in yield. Very voracious, actively breed. A characteristic feature of these beetles is that they are able to fly great distances in search of food. They can also accumulate in the soil during the permanent cultivation of potatoes. The main danger is the larvae of the Colorado potato beetle.

Control and prevention measures

The decrease in the number of the Colorado potato beetle is facilitated by the collection of larvae and adults by hand;
Regular weeding, loosening the soil and hilling plants.
To combat Colorado beetles, biological and chemicals(biological preparation "Bitoxibacillin", "Boverin"; chemical: "Tsimbush", "Dilor", "Volaton").

potato nematode

The female has a spherical body, while the male has a worm-like body. The female nematode first white color gradually darkens to brown. After fertilization, females lay eggs, their number is up to thousands of pieces, then they die off and turn into cysts that remain in the soil. The viability of larvae and cysts in the soil can be more than 10 years, so it is very difficult to deal with these pests.

signs

Plants affected by the nematode are significantly stunted, the lower part of the leaf may wither, few stems are formed, the root system develops poorly, tubers form small or they are completely absent. With a weak infection - external signs invisible. Damage will appear only after harvesting, examining the tubers you can see small cysts.

Control and prevention measures

Before planting plants, urea is introduced into possible foci of infection, which is then watered with infusion on potato sprouts;
Careful selection planting material;
It is recommended immediately after planting potatoes to water the holes with liquid chicken manure;
To combat nematodes, special preparations are also used, one of which is Nematicide (it is applied to the soil 2-3 weeks before the planned planting);
When harvesting, carry out a thorough inspection of the tubers - eliminate the infected potatoes;

potato moth

signs

The pest damages not only potatoes, but also plants such as: eggplant, tomatoes, peppers.

The main pests are caterpillars that penetrate under the peel, into tubers or stems. Caterpillars eat through the leaves internal tissues leaves, making many moves, pollute them with their excrement. After such an intervention, the stem of the plant dies.

Control and prevention measures

To combat caterpillars, a solution of 10% karbofos (45 g per 5 l of water) is used.

stem nematode

signs

Tiny roundworms(0.3 -0.4 mm), settle in the soil and potato tubers. The danger is that the affected plant does not differ in appearance from a healthy one, which makes it very difficult to fight the pest. Basically, stem nematode larvae pass into young tubers from the mother tuber, or from the soil. Actively developing, by the time of harvest, the tubers are covered with gray spots with a metallic sheen, the peel in some places exfoliates and destroyed tissue is visible under it.

Control and prevention measures

Since infection in most cases occurs through the affected tubers, for the purpose of prevention, the quality of seed potatoes should be carefully monitored;
Carry out autumn digging, removal of weeds and post-harvest destruction of plant residues.

Medvedka

The insect is a pest, lives in the soil, digs passages in the ground, harms young shoots, gnawing through the underground parts and tubers.

Control and prevention measures

To combat the bear, they use baits prepared with their own hands from boiled grains of corn, millet, barley, pickled with metaphos (25 g). 15 g of vegetable oil is added to 0.5 kg of grain and mixed well, then laid out in the holes of the bear or directly into the soil, a few days before planting. When shoots appear - lay in the aisle.
In case of mass reproduction of the pest, the soil of the plants is watered under the root with a solution of 10% karbofos (30-50 g per 10 l of water), the consumption of the solution is 6-8 l per 1 sq.m.
Also good results shows the finished granular preparation "Medvetoks". It is introduced into the furrows between the beds or along their perimeter, then watered abundantly. The granules work for more than three weeks, without disintegrating even in very wet soil. After eating one granule of the drug, the bear dies within a few hours.

Scoop caterpillars

Caterpillars damage potato tops and tubers. During the growing season, they penetrate the foliage (sometimes into the stems and tubers) and make many moves. Damaged tissues become a good environment for the development of various microorganisms that cause the development of rot (dry and wet). Stems wilt, warp, dry out, or break in places damaged by cutworm caterpillars.

Control and prevention measures

To combat caterpillars, scoops use drugs: "Decis", "Tsimbush".

Potato diseases

Late blight (potato rot)

signs

This disease affects all parts of the plant: potato tubers, stems and leaves. The first signs appear on the lower leaves of the plant, which are more protected from direct sunlight, dark brown spots appear on them, and on the reverse side - a white coating. This phenomenon means that a fungus is present on the plant that causes late blight disease. After some time from the infected tops, the disease is transmitted to the tubers.

The disease spreads especially quickly during rains, as the spores of the fungus are washed off the plant and absorbed into the soil. At harvest, the disease is quite difficult to detect, only after a few weeks the tubers become covered with typical spots. When cutting potatoes, you can see brown stains on the pulp. The affected potatoes are not subject to storage, as a rule, they soon rot.

Control and prevention measures

Use healthy tubers for planting (for greater quality assurance, pre-sprout potato tubers before planting);
Do not plant potatoes near tomatoes when planting, and keep in mind that it is not recommended to plant potatoes for several years in a row in the same area;
During the growing season, hill the plant higher so that the resulting tubers are not too on the surface.
The best effect on the fight against late blight is shown by spraying the tops with chemicals. At the moment the plants reach a height of about 15-20 cm, carry out preventive treatment with a solution of copper sulfate (for 5 liters of water - 5 g of the drug);
At the first sign of infection, spray the plants with a 1% solution of Bordeaux liquid, which you can easily prepare yourself (remember this recipe, it will come in handy more than once in the fight against other diseases and not only potatoes).

How to make Bordeaux liquid

To prepare Bordeaux liquid, you will need two containers (preferably glass ones);
Pour 3 liters of water into one container and dissolve 120 g of quicklime in it;
In the second container in 3 liters hot water dissolve 60 g of copper sulfate;
Pour one liquid into another and mix thoroughly. Everything, the solution is ready for spraying!

Rhizoctonia

signs

A fungal disease that affects sprouts, stems and tubers. Tubers that have been germinated in the dark are especially susceptible to the disease. Dark or brown ulcers appear on their sprouts, leading to partial death of the sprouts. Affected shoots may produce side shoots also affected by the disease. On the formed tubers, rhizoctonia appears as hardened dark lumps that are easily peeled off. With this disease, delayed germination, developmental delay, premature wilting and, as a result, a yield loss of 15-20% are noted.

Control and prevention measures

Planting should be carried out with germinated tubers (previously moistened in a 1.5% solution boric acid), in well-warmed soil, not less than 8-9 ºС;
Control the condition of the soil: follow the optimal watering, do not allow the appearance of a crust on the surface;

common scab

signs

Young shoots and growing tubers are especially susceptible to the disease. Scab appears on the surface of the tubers in the form of rough, dry ulcers, which, when growing, merge into a rough crust. The tissues of young sprouts are destroyed, germination is reduced, affected tubers rot. Plants are more susceptible to this disease - growing on sandy soils, less - on clay.

Control and prevention measures

For planting, choose only healthy tubers, pre-treated in a formalin solution (0.25 liters of 40% formalin per 50 liters of water). Dilute formalin in a large container into which you can drop a wicker basket with potatoes. Soak the potatoes in the solution for 3 minutes, then let the liquid drain and pour the tubers onto the spread matting. Cover with a tarp for 2 hours. Please note that germinated tubers cannot be processed.
Avoid growing potatoes on soils that are too calcareous and fertilized with fresh manure - this is a favorable environment for the active reproduction of scab in the soil.
Carry out pre-sowing tillage with fertilizers; ammonium sulfate (35-40 g per 1 sq.m.), potassium magnesia or superphosphate (30g per 1 sq.m.), or right before planting potatoes, add manganese sulfate to the wells (2 g per well), good mixing with earth.

macrosporiosis

signs

This disease spreads to the foliage, stems, and tubers of potatoes mainly in the first half of the period of active growth. The disease manifests itself as many dry dark brown spots all over the leaf surface, at first with clear contours, and later they increase in size and merge into solid black. The foliage dies off, and after a while the trunk is also affected by gray-brown ulcers, rotting in rainy weather and drying in the sun.

Control and prevention measures

Adhere to the principle of fruit change (in one place you can grow potatoes once every three years);
Plant potatoes as far away from tomatoes as possible, as this crop is also susceptible to this disease;
Apply potash and phosphate fertilizers to the soil;
For prevention - once a week, spray potatoes with a solution of copper oxychloride (20 l of water / 80 g of the drug) or 1% solution of Bordeaux liquid;
Good results are shown by treatment with Polycarbicin (20 g per 5 l of water), Arceride (25 g per 5 l of water).
For greater efficiency the fight against macrosporiosis, drugs should be alternated, as addiction occurs.

signs

very dangerous fungal disease, is one of the quarantine diseases of potatoes. Upon detection this disease, the tubers are to be destroyed, and the soil of the site is disinfected, then the soil is no longer suitable for growing potatoes.

At the first stage, small white growths similar to cauliflower heads appear on plants infected with the disease, later they darken and eventually turn black, turning into a mass of mucus. Cancer disease can spread with infected tubers or soil on them, tools for tillage.

Control and prevention measures

One of the most effective measures against the spread of potato cancer is the cultivation of disease-resistant varieties.

Difficult to find household plot Wherever potatoes are grown, it is not for nothing that they call it the second bread. But such harmful insects as the potato armyworm can cause serious damage to the crop. To prevent this from happening, you need to regularly inspect the bushes. Moreover, there are a lot of pests who like to eat potatoes. In order not to lose the crop, all precautions must be observed.

Before resorting to chemicals, safer control measures can be tried to get rid of insects on potatoes. Especially if the area is small. The number of time-tested methods is enormous. It is only necessary to notice in time that the leaves begin to dry out, and the bushes do not grow well.

Potato pests and their control by folk methods:

Potassium permanganate. The simplest and most common recipe for potato pests is a solution of potassium permanganate. For 1 l warm water you need to take 50 g of potassium permanganate and spray the bushes with the resulting solution. This method will quickly remove insects from the site.
Wood ash. You can also spray the bushes with a solution wood ash and warm water if insects began to eat potatoes. During the planting of tubers, a small amount of ash can be poured into each hole. This will scare away insects that are in the ground and gnaw potatoes, and also prevent the appearance of larvae in the soil. If a wireworm appeared on the site, then lime flour is added to the wells along with the ash.
Traps with beer. To save potatoes from a bear, they usually make traps with beer. On the site you need to arrange bottles of beer, its smell attracts the bear. The insect will quickly disappear from the garden. And to in early spring get rid of the Colorado potato beetle, then you can scatter chopped potatoes all over the site.
Digging up the site. To prevent the appearance of potato pests in advance, in the fall, after harvesting, you need to dig up the site. Most insects prefer to winter in the ground and lay their larvae there.

Who's eating potatoes?

But not only insects can spoil the potato crop. Often a mouse or shrew gnaws potatoes. It is very simple to understand that it is rodents that spoil the tubers. On the tubers, teeth marks are clearly visible.

The larvae of the Colorado potato beetle can also gnaw potatoes in the ground. The pest gnaws small holes in the tubers. If there are a lot of larvae, then the potatoes can be heavily eaten. When harvesting, you can sometimes see the larvae inside the potatoes.

Another pest that gnaws on tubers is the wireworm. Eating tubers, he gnaws "passages" in them, as if piercing with wire.

If it is relatively easy to deal with beetles that eat tops on potatoes, then it is much more difficult to deal with underground pests.

What are the control measures against potato aphids?

Despite its name, potato aphid can appear not only on potatoes, but also on other crops. The control measures will be similar.

The potato aphid is a small insect with an elongated body. As a rule, it is green. There are two types of aphids:

Winged.
Wingless.

The winged potato aphid is slightly larger.

At first, it is very difficult to understand that bugs appeared on potatoes. They form colonies on the underside of the leaf and at first there are no visible changes on the leaves. They begin to actively gnaw on the tops of potatoes when the colony increases. Then the aphids move to the outer side of the leaves, feeding on young and juicy shoots. The tops begin to dry out gradually.

We fight on potatoes with aphids:

First of all, you should dig up the site in autumn and spring, since aphids prefer to winter in the ground. Weeds should also be destroyed regularly. After all, it is their appearance that contributes to the development of aphids on tops.
If ants have appeared on the site, then urgent measures must be taken to combat them. After all, it is they who carry aphids to the places where the anthill is located.
Such drugs as Rovikurt, Fosbecid and Aktellik have proven themselves well. At the first sign of the appearance of potato aphids, you can spray the bushes with these preparations.

How to get rid of potato moth?

What is the description and treatment of potato moth? Potato moth is a dangerous pest that can cause serious crop damage. Adults are small butterflies Brown. But the moth larvae pose the greatest danger to tubers.

The larvae that eat potatoes are characterized by a yellow-pink body, which reaches a length of 1 to 3 cm.

The fight against potato moth:

In order not to have to fight it, when landing, you need to dig deep holes. And during hilling, the height of the soil layer should be at least 15 cm.
If the moth has already appeared, the bushes are sprayed with chemicals. You can use drugs from the Colorado potato beetle. But it should be remembered that in this case it is possible to harvest the crop not earlier than in a month.
Often, moths appear in the basement where potatoes are stored. There is salvation from it. To do this, you need to take lepidocid and planriz (2 l: 0.5 l). Dip the potatoes in the solution for 20 minutes. After 3-4 days, potatoes can be eaten.
So that the moth does not start during the harvest, then it is worth digging it up until the tops have dried up. To do this, 1 week before harvesting, all tops are mowed. There should not be tops on the site, they are immediately collected and thrown away.

Fighting the potato scoop

The potato scoop is a small butterfly that looks like a moth of a brown hue. A sexually mature individual does not cause much harm to potatoes, which cannot be said about caterpillars.

Scoop gnaws holes right in potato tubers, thereby causing great harm to the crop. A worm appears mainly on waterlogged soil, so if long time there were prolonged rains, then the probability of the appearance of cutworm larvae is high. The larva crawls along the stem inside the tuber and begins to eat it from the inside, without touching the peel and leaving no holes in it.

How to deal with potato cutworm larvae:

Nemabakt. If the bush has become painful, then you can use the drug Nemabact. You need to breed it according to the instructions and process the area with potatoes. It is better to buy a product in specialized stores so as not to purchase a fake.
Sagebrush. The scoop does not tolerate the smell of wormwood. To prepare a decoction, you need to take 3 liters of water and 1 kg of wormwood. Boil the broth for about 20 minutes. Then let it brew and strain. Potatoes should be watered before the flowering period and 2 weeks after it begins.
Prevention. The potato cutworm will not lay larvae if, after harvesting the potatoes, the area is dug up and all weeds are removed. You also need to regularly weed the beds.

How to get bed bugs out of potatoes?

How to deal with bedbugs in the Irkutsk region? Bed bugs can also ruin a potato crop if you don't start fighting them in time. Bed bugs found on potatoes are called cruciferous bugs. Most often found on cabbage.

Ways to get rid of bed bugs:

chemicals. It is better to use chemicals if the bugs have begun to multiply actively and cause serious damage. You can use any preparations against pests of agricultural crops (Aktara, Gladiator, Zolon, Fagot).
Onion peel. Bedbugs do not tolerate the smell of onion peel, so to deal with them you need to take 1 kg of peel and 5 liters of water. Prepare a decoction and water the beds with it, Special attention focusing on areas where bedbugs appear in large numbers. You can also use a decoction of wormwood.
Traps. If you do not start taking action in time, then the bugs will eat the entire crop. Therefore, among the beds, you can lay out a cloth soaked in kerosene.

How to deal with cicadas?

Cicadas not only eat parts of plants, but also suck out the juice from them, thereby causing damage to the crop. The cicada looks like a fly, only gray-green in color.

Fight the cicada as follows:

Tops after harvesting should not be on the site. An insect can lay eggs on it and in the spring the larvae will begin to actively hatch.
Near the site you can hang several feeders. Birds eat cicadas, thereby preventing them from breeding in the area.
If the soil was heavily contaminated, then for several years in a row, onions or garlic should be grown in this place.
An effective method of pest control is chemicals. The drugs Akarin, Calypso and Decis have proven themselves well. It is desirable to spray potatoes in warm, calm weather. The best time is early morning or evening. It is important to ensure that the drug falls on the lower part of the leaf, because it is from this side that the cicada eats the tops. If part of the solution remains after processing, then it must be poured out.
Garlic infusion will help get rid of the larvae that the cicada lays. 300 g of green garlic pour 3 liters of water and leave for a week in a dark room in a closed container.

How to remove a potato skewer from the site?

From insects that infect potatoes, the most effective means of control is prevention. Potato skewer is also often found in plots. Shpanka eating potato tops is very dangerous if you do not get rid of it in time. This is a small black bug.

As a rule, black larva is found in the south, but due to the fact that winters are not so frosty, and summers are hot, the Spanish larva may also appear in the central regions.

How to get rid of skewer on potatoes:

You can collect the shpan manually if there are not very many beetles on the site. But you should be aware that the insect releases a substance that, when it gets on the skin, can cause abscesses and inflammation. Therefore, it is recommended to collect the shpank in tight gloves.
The second way is to treat the bushes with pesticides. You can use any chemicals against insects.

How to get rid of a potato ladybug?

The potato ladybug is a small bug, wings and an orange-colored body. There are black dots on the wings. The potato ladybug feeds on the leaves without touching the veins. Over time, the leaf begins to dry out and dies.

The potato ladybug is practically indestructible. The only way to get rid of it is to spray the bushes with chemicals. But after a while, most likely, the bugs will reappear.

You can use special biological preparations. Their main advantage is that they are harmless to humans. But there is one significant disadvantage - during the rain they are quickly washed off from the plants. Therefore, you need to spray the tops on a sunny day.

Pests and their habitat

You need to regularly inspect the entire bush in order to notice pests on the site in time. But, depending on which part of the plant will dry out, you can make an assumption which insect has started on the site:

The potato fly prefers to breed mainly on leaves.
Potato foliage is eaten by insects such as the Colorado potato beetle and its larvae, leafhoppers and potato flea.
The stems of the bush are often affected by Colorado potato beetles, potato moth, cutworm and mole cricket (underground parts of the stem).
Potato tubers are gnawed by mice, moles, wireworms, nematodes, a bear and potato scoop larvae.

The easiest way to prevent some insects is to dig up the area and remove weeds in time, as well as inspect the potato bushes. Then the harvest will be good.

It requires from the farmer not only proper care and watering, but also knowledge of the intricacies of the fight against the Colorado potato beetle and complex diseases. Having learned to cope with late blight, actinomycosis, rhizoctonia, macrosporiosis, phomosis and viral diseases, the agrarian will be able to save the crop from death.

Pests

Persistent and most dangerous potato pest. Also damages eggplants, peppers, tomatoes.

The beetles are egg-shaped, convex above, flat below. There are 10 black stripes on the elytra. The length of the beetle b-7 mm. The larvae are worm-shaped, orange-red with a black head and two rows of black dots on the sides. The length of the larva is up to 16 mm.

The beetle develops in two generations per year. Beetles hibernate in the soil at a depth of 20-80 cm, mainly in areas that have come out from under potatoes and tomatoes. In spring, beetles appear on the soil surface with the emergence of potato seedlings. The exit of beetles from wintering places is unfriendly: beetles that hibernated closer to the surface emerge earlier. In this regard, oviposition and hatching of larvae is extended over a long period. Some of the beetles remain in the soil until the next spring.

At first, the beetles stay under lumps of soil, at the base of plants, crawling out onto the leaves only in the warm part of the day, and feed sluggishly. As the temperature rises, beetles feed more intensively, mating and oviposition occur. In search of food plants, beetles can fly a long distance. The females lay their eggs on the underside of the leaves. In one clutch there can be up to 60-70 eggs. The orange-yellow eggs on the green background of the leaf are clearly visible, which makes them easier to collect and destroy. The female's fertility is up to 600 eggs.

The development of the egg, depending on the air temperature, lasts from 5 to 17 days. The larvae develop for about a month. Then they go into the soil, where they pupate at a depth of 5-15 cm. The pupal stage lasts 6-15 days. Young beetles emerge from the soil with immature, lighter covers. They immediately start feeding, mating and laying eggs. Beetles of the second generation leave for wintering.

Control measures. Regular manual collection of beetles, eggs and larvae and their subsequent destruction. Efficiency manual collection insects are higher during the warm hours of the day when beetles and larvae are on plants. Spraying potatoes in the spring when larvae of the 2-3rd age (2-3 mm in length) appear and again after 8-12 days. Two sprays are also carried out against beetles and second-generation larvae. For spraying, drugs are used: karate, sherpa, fiyori, sumi-alpha, arrivo or kinmiks. Of the biological products, bitoxibacillin is recommended during the period of mass hatching of beetle larvae of the first and second generations. Spraying twice, with an interval of 6-8 days. The effectiveness of bitoxibacillin increases at an air temperature of + 20 ° C and above.

Nematode - a worm 1-1.3 mm long. Damages aerial parts and tubers of potatoes. To a lesser extent harms peas, carrots, tomatoes and other plants. Lives on sow thistle, dandelion, nightshade.

The source of infection is planting material. From infected planted tubers, the nematode passes into stems, and then into young tubers. Each female lays up to 250 eggs. Signs of infection: a shortened and thickened stem, small corrugated leaves. Gray spots appear on infected tubers, the tissue darkens, the skin lags behind, and the flesh becomes rotten. In storage, the nematode moves from infected tubers to healthy ones. Mechanical damage to the tuber facilitates the penetration of the nematode into it. Elevated temperature and humidity favor the reproduction and spread of the nematode.

Primary infection can occur through the soil, through containers, inventory.

Control measures. Careful sorting of seed potatoes and culling of tubers infected with the nematode. Compliance with the alternation of crops: potatoes should return to their original place in 3-4 years. Weed control on which the nematode can live. Digging the soil in autumn.

Diseases

Phytophthora

The most common and harmful disease of potatoes, causing premature drying of the tops and rotting of tubers. Cool and wet weather is favorable for the development of the disease. In addition to potatoes, the fungus infects tomatoes.

Symptoms of the disease become visible after flowering. Dark brown oily spots appear on the leaves. In wet weather, the spots increase rapidly, and on the underside of the leaves, in places where the tissue is damaged, a plaque of conidiophores with conidial spores is formed. Wind and rain promote the spread of spores. Once on healthy leaves, the spores germinate, the seedling penetrates the leaf through the stomata. A healthy leaf is infected. Diseased leaf tissues turn black and dry. Elongated brown spots-stripes appear on the petioles and stems, eventually covering their entire surface.

Tubers are affected by late blight during the growing season and during harvesting. During rains, the spores are washed off the leaves with water, and with it they penetrate the soil, infecting the tubers. During the harvest period, tubers become infected by contact with infected tops. In storage, infection of healthy tubers from diseased tubers does not occur, although the development of the fungus continues in previously infected tubers. Brown sunken spots appear on infected tubers. The tissue under the spots turns brown, gradually spreading deep into the tuber. Fungi and bacteria easily penetrate tubers affected by phytophthora, causing rapid rotting of the tuber. Late blight-infected tubers, when planted in the spring, produce diseased plants, from which the infection spreads to healthy plants.

Control measures. Rotation of crops on the site. Potatoes should return to their original place no earlier than after 3-4 years.

Planting potatoes with healthy tubers: tubers intended for planting in the spring are carefully sorted, culling out the sick, germinated in the light of 20-25 days before planting at a temperature of + 18 ... + 20 ° C.

Planting tubers in optimal timing(with early planting of tubers, potatoes are more often affected by late blight).

Two-three-time hilling of plants during the growing season. Tubers located on the surface or close to the soil surface are infected with phytophthora more often and earlier.

Spraying plants during the budding period - at the beginning of flowering, when the first signs of the disease appear, with one of the following drugs: 1% Bordeaux mixture, copper oxychloride, arceride or ridomil. In wet years, if necessary, spraying is repeated 2-3 times with an interval of 5-8 days. The last spraying is carried out no later than 15 days before harvesting.

Mowing and removing potato tops from the site 2-3 days before harvesting the tubers. This will avoid contact of tubers with infected tops.

Harvesting tubers in dry sunny weather, drying them well in the sun and in the wind.

Sorting of tubers before storing them with a selection of diseased potatoes.

Common scab (actinomycotic)

Widespread potato disease. The causative agent of the disease - a fungus - affects potato tubers. On tubers, the fungus forms cracking warts or ulcers. Ulcers can merge and cover the entire surface of the tuber or a significant part of it. Sometimes ulcers appear on the stolons and roots of potatoes. Affected tubers are poorly stored. Other fungi and bacteria penetrate the ulcers, the tuber rots. The starch content in diseased tubers is reduced.

The sources of infection are soil and planting material. Dry and hot weather is favorable for scab development. Contribute to infection various damage tuber skins.

Control measures. Alternation of crops: potatoes can be planted in their original place only after 3-4 years.

Careful selection of planting material: only healthy tubers should be planted.

Black scab (Rhizoctonia)

The fungus infects potatoes, many nightshade, pumpkin, cruciferous plants.

The disease manifests itself on potato sprouts in the form of black spots and sores. Diseased sprouts die off, often without having time to reach the soil surface. During the growing season, the fungus infects the base of the stems and roots. On diseased stems in wet weather, a dirty white felt coating of spores is formed. The spores disperse around, infecting the soil and tubers. The surface of infected tubers is covered with numerous small black sclerotia, similar to lumps of earth. This form of the disease is therefore called black scab.

Sclerotia and mycelium of the fungus overwinter in the soil and tubers. Tubers and soil are the main sources of potato infection in spring.

Control measures .. Alternation of crops on the site: potatoes are returned to their original place no earlier than after 3-4 years. Selection for planting healthy, disease-free tubers. Timely weeding and hilling of plants.

The causative agent (fungus) affects potatoes, tomatoes, eggplants. The disease manifests itself on the leaves as large (up to 7 mm) rounded or angular dry brown spots. On the spots there is an inconspicuous plaque of sporulation. Affected leaves dry up. The fungus rarely infects tubers, causing brown sunken spots to appear on them.

The most intensive development of the disease is observed before the flowering of potatoes. A sufficiently high temperature of +24 ... +25 C is favorable for the development of the disease. The fungus remains on the remains of affected plants.

Control measures.

Compliance with the alternation of crops when potatoes return to their original place no earlier than after 3-4 years.
Mowing tops and removing them from the garden before harvesting potatoes.
Removal of vegetable residues from the garden in the fall.
Digging the soil.
Spraying potato plants with 1% Bordeaux liquid, copper chloride or arceride when the first spots of the disease appear on the leaves and again after 6-8 days.
Mowing the tops and removing them from the site 3-5 days before harvesting the tubers.

Fusarium (dry rot of tubers)

The fungus infects tubers during storage and aerial parts of the plant during the growing season. Penetrating from the soil into the vascular fibrous bundles, the fungus clogs them, causing the plant to quickly wither and dry out.

Depressed grayish-brown spots first appear on the tubers; The damaged peel shrivels, and the flesh becomes dry and rotten. Rot quickly spreads throughout the tuber. The rotten tuber remains dry and light. On the surface of the diseased tuber, sporulation pads develop. Spores infect healthy tubers. Fusarium infects, first of all, tubers damaged by insects or having mechanical damage. Infection can also occur with mycelium if the diseased and healthy tubers are in contact with each other.

The fungus persists for a long time in the soil and on plant debris. It enters the storage with soil adhering to the tubers.

Control measures.

Alternation of crops with the return of potatoes to their original place no earlier than after 5 years.
Removal from the garden and destruction of diseased plants.
Bookmark for storage selected only healthy tubers that do not have mechanical damage and damage by insects, without signs of other diseases.
Drying tubers before storage.
Cleaning and disinfection of storage facilities, their periodic ventilation during storage of tubers.
Bulkhead tubers during storage with the removal of potatoes with signs of disease.

fomoz

Fungal disease of tubers and stems. During the flowering of potatoes, elongated spots appear on the stems and petioles of the leaves. Later, spores develop on the spots. With the help of wind and rain, spores fall on healthy plants. Diseased plants lag behind in development, wither. On tubers, the fungus causes the formation dark spots round shape. The tissue under the spots becomes brown, cavities with a gray coating on the walls are formed inside the tuber. After a while, diseased tubers rot completely.

The source of infection are diseased tubers and plant debris.

Control measures.

Alternation of crops with the return of potatoes to their original place after 4 years.
Selection for planting healthy tubers.
Pre-harvest mowing of potato tops and its removal from the site.

ring rot

Bacterial disease is common. Aerial plant organs and tubers are affected.

The source of the disease is infected tubers. When diseased tubers are planted, bacteria penetrate from them into the vessels of the stem, and through the stolons into the vessels of growing tubers. During the harvesting of potatoes, bacteria can get on the tubers when they come into contact with diseased tops. Violation of the integrity of the skin of tubers during

the time of cleaning or transportation facilitates the penetration of bacteria into them. The development of the disease during the growing season is favored heat And high humidity air.

Symptoms of the disease appear before flowering and during the flowering of potatoes. On diseased plants, yellowing and curling of the leaves are first observed. Then the tops wither and dry out. Vessels of the stem of dead plants darken, they are filled with yellowish mucus containing a lot of bacteria. In diseased tubers, external signs of the disease are not visible. A diseased tuber is easy to recognize if cut open. On a fresh section of a diseased tuber, a yellowish-dark ring of vascular bundles clearly appears near its surface. The tissue of the vessels is soft; when the tuber is compressed, yellowish mucus is squeezed out of it with accumulations of bacteria in it. On a section of a healthy tuber, the ring of vessels does not differ in color from the rest of the tuber mass. A diseased tuber gradually rots.

Control measures.

Selection for seeds of healthy tubers that do not have signs of disease and mechanical damage.
Removal of diseased plants from the garden when inspecting potato plantings during flowering and later.
Pre-harvest mowing of potato tops and its removal from the garden.
Harvesting when the tubers are fully ripe, when their skin becomes coarse.
Drying tubers before storage with a sample of patients.
Digging the soil in autumn with careful incorporation of plant residues.

Virus diseases of potatoes

In the south of Russia, potatoes are affected by many types of viruses. The most common viral diseases are listed below.

Mosaic. It affects potatoes and wild nightshades. The disease appears on the leaves as alternating light green and dark green areas. Mosaic (variegation) of leaves is more pronounced during the flowering of potatoes. The virus persists in tubers. From a diseased plant to a healthy one, the virus is transmitted by sucking insects (aphids, bedbugs, cicadas).

Wrinkled mosaic. The leaves of diseased plants become wrinkled, acquire a light, often variegated (mosaic) color. They tie, hang down. The stems become coarse and become brittle. The virus persists in tubers.

Striped mosaic. Attacks potatoes and tomatoes. The disease manifests itself in the form of black angular spots of dead tissue on the leaves and black stripes on the stems and petioles. Diseased leaves dry up and fall off, starting from the base of the plant. Stems become brittle and die quickly. Through the vessels, the virus penetrates from the tops into the tubers and remains in them until the potatoes are planted.

Rolling leaves. The virus infects potatoes and tomatoes. The leaves of diseased plants curl up. Leaves become brittle, plants slow down growth. The virus overwinters in tubers.

Measures to combat viral diseases:

use for planting tubers from healthy plants;
selection of planting material in spring; culling of tubers with weakened, filamentous sprouts, with spots of dying tissue;
regular inspection of potato plantings and removal of plants with signs of viral diseases;

Each individual type of pest spoils the various components of potato tubers, leads a different lifestyle. For effective fight with an uninvited guest, it is necessary to identify the type of pest, use the necessary means.

Find out how to cook the most effective one at home, as well as which one is better to choose in the store.

It has a yellow-brown color, the body length does not exceed one centimeter. Longitudinal stripes are visible on chitin, the appearance of the pest is familiar to all gardeners. Adults, larvae completely destroy the leaves, fruits of potatoes. When a beetle appears in the garden, the yield is reduced by 60%.

There are several ways to deal with a beetle:

the use of systemic chemicals (Sonnet, Commander,). Apply funds at least three times to obtain the desired result. Carry out the last treatment no later than twenty days before harvest;
spraying potato tubers with preparations of bacterial / fungal origin (allowed to use, Boverin). Remedies against harmful larvae that do not have a protective chitinous layer are very effective. The peak of the positive effect of the funds falls on the 7th day after spraying. Reapply as needed.

Additionally, you can spray potato bushes with strong infusions of tansy, peppermint, blackcurrant.

Advice! The mechanical removal of adults and larvae of the Colorado potato beetle will help to increase the chances of a successful fight.

Wireworm and false wireworm

The female nematode has a round body shape, the male resembles a worm. Females are initially white, then darken to brown. After fertilization, one female can lay several thousand eggs. After some time, they die off, turn into cysts, then remain in the soil. In the spring, they begin to actively eat potatoes. The life span of cysts is up to ten years, so it is quite difficult to overcome nematodes.

It is very difficult to cope with nematodes, they will help to get the desired result useful advice experienced gardeners:

before planting potatoes, treat the soil with urea; after harvesting, it is recommended to use lime;
chicken manure, which is abundantly irrigated with soil, can destroy almost 90% of harmful larvae;
alternate cultures on land plot by growing potatoes every three years;
in a specially designated place, treat the dug bushes with bleach;
severe damage by nematodes requires the use of a drug called Bazudin, which does an excellent job even with wireworms.

garden moth

The pest is a small butterfly that lays larvae. The moth harms not only potatoes, but also tomatoes, eggplants, peppers. Adults do not cause significant damage to the crop, the main damage is caused by larvae. Immediately after birth, they actively feed on tubers, stems, and are able to gnaw through the peel.

They eat away many passages in the foliage, pollute them with their waste products. After such wrecking, the plant stem weakens, the potato slowly dies. The lack of therapeutic measures will lead to crop loss over a fairly large area.

choose to land quality material, the seeds can be heated to 40 degrees to prevent infection of the future crop;
at each stage of planting, check the quality of potatoes, their storage conditions;
before the winter period, carry out deep processing of the soil;
Treat the soil with a strong methyl bromide solution before planting seeds in the soil.

scoop

They are small moths, body color ranges from brown to gray. Insects are unpretentious, quickly adapt to environmental conditions, resistant to poisons. The fight against the armyworm should be complex and include many aspects. For potatoes, the most dangerous larvae are: they penetrate the root crops, actively feed on them, leading to the death of the plant.

This insect must be fought in the complex:

regularly destroy weeds that contribute to an increase in the population of potato scoop;
use pheromone traps aimed at killing adults to prevent laying eggs for the winter;
use insecticides, spraying them will help destroy existing caterpillars. To do this, you need to purchase Decis, Tsimbush.

potato flea

Many varieties are distributed throughout the world. Adult beetles, reaching three millimeters, actively feed on potato tops. Thin larvae have three pairs of legs, develop in the root system of potatoes. At favorable conditions cause damage to a large number of potato crops.

Tuber infection is favored by hot weather or late boarding. You can spot a pest in potatoes by specific marks on the leaves.

You can deal with a flea using the same methods as with a cicada, also use glue bait traps. For small gardens, you can use a mixture of chamomile decoction, ash, tobacco dust in the same proportions.

It is quite realistic to prevent infection by various pests of potato plantations, following useful recommendations:

stick to the rules of crop rotation (do not plant the same crop in the same place every year, take a break for at least three years);
buy a seed product only in trusted stores, warm it up at a temperature of 40 degrees before sowing;
regularly inspect potato plantations, if pests are found, immediately deal with their extermination.
