Bright and harmful ... beetles - firefighters
Back in July, some flower growers could notice gnaws on the leaves and even petals of lilies, significantly spoiling the appearance of flowers, especially from a commodity point of view. Since some lily hybrids still bloom in August, for some this question may still be relevant.
Who eats them?
Aerial parts of lilies and other plants can damage 2 types of Lilioceris: lily beetle(L. lili) and onion ratchet, or onion daylily(L. merdigera). The first is a red beetle with a black head, 6–9 mm in size, and the second is red all over the top, occurs and harms much more often. Both species belong to the leaf beetle family, from which the Colorado potato beetle is better known.
An adult onion ratchet is a small (7-8 cm) elongated oval beetle with orange-red elytra and a black abdomen, it is also called the onion leaf beetle, it hibernates in the soil, comes to the surface at the end of April. In addition to all types of lilies, the beetle can destroy the foliage of plants of the following crops: onions, hazel grouse, tobacco, potatoes, kupena and other plants. It is worth noting that hazel grouses, especially small species, can be eaten clean by lilioceris. And not only leaves, but also green boxes with seeds.
As leaf beetles, they actively gnaw on leaves, as well as buds and flowers. Females lay eggs from May to July.
The larvae emerging from the eggs are very untidy in appearance; not only are they covered with mucus, they are also in the habit of smearing themselves with their own excrement. Perhaps this serves as protection from the burning rays of the sun. Larvae of the first instars skeletonize leaves (eat soft tissues leaving veins). Older ones gnaw pieces out of them. They feed on the plant for 2-3 weeks and pupate.
How to get rid. If your plantations are small, then be sure to use chemistry, it is enough to collect and destroy beetles and larvae manually several times during the summer. The beetle usually sits openly, it is clearly visible, but you need to have some skill, because at the slightest danger it tightens its paws and falls to the ground with its back down. Black-brown belly with 
it flows with the soil, and finding a pest can be quite difficult. Of course, picking by hand, especially larvae, is unpleasant, but it is reassuring that they do not emit poisonous and skin-irritating substances, like some other insects.
If the plantations are decent. Many of the insecticides used against the Colorado potato beetle are suitable for spraying. The specificity of this pest is that in the surrounding nature there is always its reserve. You collect, you poison some, others fly in. In nature, the onion leaf beetle feeds mainly on lilies of the valley.
Of the insecticides, systemic ones are considered more reliable: Actellik (1.5 g / 10 l), Aktara. Their peculiarity is that they are assimilated by plant tissues, which for some time become poisonous to the pest. However, before buying and even more so using this or that drug, pay attention to such regulations for its use as the waiting period - the period (number of days) that must pass from the moment of processing to the use of plants: for Aktellik it is 20 days, and for Actars - 14. That is, to spray lilies with them and vegetable crops follows respectively 3 and 2 weeks before cutting. If the larvae were found at the time the buds began to bloom, then these chemicals can no longer be sprayed. Accordingly, in this case, you can either collect manually, which is disgusting, or use biological products such as Fitoverm and Bitoxibacillin, the waiting times for which are 2 and 5 days, respectively. To reduce the number of the pest, it is very important not to let it multiply. We must try to find and destroy all the found larvae, preventing their pupation.
Amateur flower growers who grow lilies often encounter flower pests - red bugs.
Insects attack beautiful plant and soon it will die.
Description of the pest
The fire beetle belongs to the leaf beetle family and is a great threat to the leaves of the flower. Today, two types of pests are common: onion rattle and lily rattle. Insects eat the foliage very strongly, sometimes you can find a plant with a bare stem.
Important! If you ignore the invasion of "firefighters", their larvae are able to eat the plant completely in 4 weeks! As soon as pests have been discovered, it is necessary to start an active fight against them. 
- Onion cracker. This pest is a leaf beetle with a bright red body and head. Thanks to powerful jaws, the pest can eat not only foliage - its prey is the buds, flowers and stem of the plant. The main target of leaf beetles are lilies of the valley and lilies. That is why they have another name: "lily beetle."
- Lily rattle. Another pest of lilies, the so-called red beetles. They have a rather attractive appearance, have rigid wings. Among the people, such pests are called "firefighters" because of their colors. They have an elongated red body and a black head.
Harm in the garden
Leaf beetles moved to summer cottages relatively recently: back in the 90s, they lived exclusively in forests. Today, the lily beetle is quite common in the garden, and you need to know how to deal with it. 
Did you know? The larvae cover themselves with mucus from their own excrement. In this way, they protect themselves from birds that ignore the young, which they mistake for their feces. Undoubtedly, adults are capable of harming plants in spring, but it is not so great and is not capable of leading to the death of a flower. It is necessary to beware of larvae: they appear on the lower part of the leaves a little later, have an orange color. During one season, one leaf beetle lays approximately 450 eggs, from which several generations can hatch.
About a week after the eggs are laid, the larvae appear Pink colour. They are located under the sheet, so they are quite difficult to notice immediately. The larvae are very voracious and can eat all the leaves on the flower, leaving only the stem. 
After 2-3 weeks, they move to the soil, where their transformation into pupae begins. orange color. After 3 weeks, red pests go hunting. For the winter, they hide in the ground or fallen leaves.
Important! When planting lilies, it is worth laying a garden film between the rows - this will prevent the beetles from digging into the ground, and you can quickly destroy them. Leaf beetles attack plants very quickly, and sometimes you may not have time to enjoy the beauty of flowers.
How to deal with "leaf eaters"
If the red beetle began to appear on lilies, you need to know how to get rid of it. There are several pest control methods. Let's consider them. 
Manually
The simplest and safe way destruction of beetles - mechanical. They can be collected by hand or shaken into a container. The jar must be closed with a lid, since the beetles are well kept on the surface of the water and, having gathered in one heap, can easily get out of the container.
If you have a small area, this method will help to cope with the invasion of "firefighters". Beetles need to be collected several times a season. Despite the fact that insects do not irritate the skin and do not have poison, such an event should be carried out with gloves.
Chemistry
If mechanical way the fight against beetles did not bring results, it is necessary to use more difficult methods. This is about chemicals which are detrimental to insects. However, they should only be used when the lilies are not in bloom. 
Did you know? Fire beetles are very cunning: when a person approaches them, they fall to the ground with their black belly up and become invisible. After the danger has passed, they take off and start eating flowers again.
There is no drug aimed at the destruction of this particular type of pest. It is advisable to use solutions and agents whose purpose is the destruction of leaf-eating pests. Often, the same drugs are used to deal with "firefighters" as for the destruction of the Colorado potato beetle.
Over time, rattles become resistant to chemicals. If red bugs began to appear on the lily, you need to know how to treat the plant. The following drugs will have the best effect: Inta-Vira, Talstar, Decis. For effective fight with pests of plants, the following preparations are used: Nemabakt, Medvetoks, Aktofit, Kinmiks, Brunka, Calypso, Anteater, Abiga-Peak, Golden Spark and Bitoxibacillin. 
If the flower garden has big sizes, and you also found a lot of larvae, it is recommended to spray with a special solution prepared according to the instructions. Do not deviate from the recommended proportions, as this may result in burns to the plant, while the beetles remain unharmed.
Biological methods
If you want beautiful and healthy lilies to always grow in the garden, you need to prepare in advance to protect them. In specialized stores, you should purchase the necessary chemicals, sprayers, and always be ready to fight fire bugs.

Fighting the red lily beetle
Lilies, like all other flowers, get sick and are attacked by pests. Flower growers, who have considerable experience, are confident that the sooner they begin to provide assistance, the faster and easier the plant will be able to defeat the disease and heal the wounds inflicted by harmful insects.
Who are these gluttonous harmful lily leaf beetles and what needs to be done to get rid of them, you can find out from this article.
"Red Invaders"
The sun warms in the spring, the earth is freed from the snow cover, tender sprouts of lilies make their way from under it. Their delicate leaves timidly reach for the light, as if showing gratitude to spring for the warmth that it gave to all living beings!
You are just beginning to admire the beauty of bulbous plants, how they Amazing beauty starts to fade. The reason is the invasion of red beetles, which, having left the wintering, tend to quickly gain strength. To do this, they search for their favorite “dishes” in the form of lilies and hazel grouse by smell, overcoming rather long distances for this.
"Red invaders" are in the leaf beetle family. The red beetle can be seen, as they say, with the naked eye. Their color resembles the color of a fire engine, which is why the insects were rightly called the beetle - a firefighter. Two types of beetles live in our area: onion red beetles and lily (lily), which are also popularly called onion rattle and lily rattle. The name comes from the ability of this insect to make specific sounds when danger is suspected.
The wide distribution of these pests in Europe and North America due to the cultivation of lilies and the sale of their bulbs. Red beetles, which have an attractive appearance in the photo, are actually among the largest garden pests. In their natural habitats, their eggs and larvae serve as food for wasp larvae, but where the "red invaders" were transported, they are naturally safe. For this reason, the fireman is an extremely dangerous creature for plants, especially for lilies.
Enemy number 1 for lilies
Voracious red bugs that brazenly devour leaves on lilies, do not disdain even flower petals, are found everywhere in Europe. In our country, they became known at the very beginning of the nineties of the last century.
This pest loves to eat lilies most of all, although it does not ignore such plants as lily of the valley and hazel grouse. Already at the very beginning of spring, it can be seen on plantings, where it begins to devour leaves, flowers and bulbs. If you do not immediately get rid of it, then after the appearance of the larvae it will be very difficult to fight the beetle.
Adult red lily beetles have a characteristic appearance:
- Pretty big eyes;
- Sufficiently narrowed chest;
- Wide belly.
Body coloration: the area in front of the back and elytra are scarlet, sometimes bright red, the surface of the latter is shiny with depressions. Long limbs and black antennae. The rattlesnake larvae resemble caterpillars, they are also wingless with a thick, long body. Their color is yellow, brown, orange.
For larvae, birds are potential enemies. Here is what they came up with interesting way protection to envelop the body with their excrement. As a result, the feathered enemies take the young individual for their excrement and do not pay any attention to them.
Onion cracker
The second enemy of lilies is the onion ratchet or onion red beetle, resembling ladybug. It goes to the soil for wintering, appears on the surface at the end of April or at the beginning of May. An adult beetle of this species is an individual of an elongated oval shape, the size of which is not more than 7-8 cm in length. The belly is black, the elytra are orange-red. The legs are red with black dots, the black antennae are shorter than half the length of the body.
The onion rattle larva has a dirty - White color with black dots on the sides. The head and legs are black. From the side of the back, the larva is covered with unpleasant mucus and excrement.
Onion cracker damages onions, tobacco, potatoes, hazel grouse, all types of lilies and other plants. Damage to green spaces is caused by both adult beetles and their larvae, devouring leaves, green seed boxes, stems and bulbs. This insidious insect in a short time manages to pinch off a tiny piece from many buds, but this already serves as a reason that the blossoming flower will be completely spoiled.
Reproduction of lily bugs
The beginning of the mating period of red beetles falls on the middle of spring. One can often observe such a picture: insects clinging to each other sit on hazel grouses and on lily bushes. The mating process takes place in the same place where the pests eat, that is, on the leaves, and then on the lily buds. In the same places, females lay their eggs on the underside of the leaves and on the stems of the plant. Egg laying ends around mid-summer.
One individual is able to lay 450 orange eggs during the season. They then hatch into about three generations of insects! The larvae are born 7-10 days after laying the eggs. They are in a hanging position on the underside of the leaves, and it is not easy to notice them.
Measures to combat red bugs with natural methods
Protection against rattles will be effective only if all activities are carried out in a complex, one of them does not give any positive results. It is often the owners of the garden who have to enter into the fight against pests. The inhabitants of Britain came to the conclusion that if the red bugs are not destroyed in time, they will completely destroy all the lilies and hazel grouses on the island. It is useless to wait for any help from the birds, because the fireman beetle is not tasty, about which it sends a warning with its bright red color.
One of the activities is the manual destruction of pests. On small plantations, the use of chemicals is not necessary. It is necessary to collect qualitatively, then destroy the red beetles manually only a few times over the summer. Collecting them is not easy, it will take some skill. The rattlesnakes, sitting openly on the grass, are perfectly visible, but the insect, at the slightest suspicion of danger, falls to the ground with its back down. Black - Brown the abdomen is at the top and practically becomes one with the ground, it is quite difficult to see beetles in this position.
Of course, the work of collecting insects, especially larvae, is very unpleasant. The only good thing is that they are not poisonous and are not capable of irritating the skin, as other harmful insects do. But, most importantly, to see your flower garden beautiful and healthy!
Herbal infusions as a method of dealing with red beetles
The complex for protecting plantings of lilies from red beetles consists of observing crop rotation, as well as regular destruction of weeds with the root, spraying plants in problem areas during the feeding period of larvae with herbal infusions. This is wormwood and high larkspur. To prepare the solutions, you will need the tops and leaves of wormwood, harvested during the flowering period, and the entire plant of high larkspur. It is better to cut it at the beginning of flowering.
Wormwood solution: fill the bucket completely with chopped fresh wormwood grass or 800g. dried. To fill with water room temperature. Infuse for a day, then simmer for half an hour over low heat. Before use, dilute the solution, taking one part of the broth and one part of water.
Solution for spraying from larkspur: place a kilogram of crushed potion in a bucket, pour cool water, leave to infuse. Strain on the third day. The solution is ready, you can start spraying.
In order for the solution to cling to the leaves, it is recommended to add one of the surfactants to it: soap solution, the cheapest shampoo or a little PVA glue.
In order for the onion red beetle to bypass lilies and other green foods that are pleasing to it, spraying plants with these preparations should be carried out several times with an interval of one week.
Control of red beetles using chemicals and biological control methods
It happens that the collection by hand did not bring any results and the "red invaders" aggressively go on the offensive, which means it's time to use the "heavy artillery", which consists of their chemicals. They are used only when a large number of larvae appear not when the lilies are in bloom.
Currently, there is no drug that would be intended for the destruction of lily pests - red beetles. In cases of invasion of rattles on plants, chemical preparations are used to combat them, which are capable of infecting other leaf-eating insects. Especially often these are the means that are used in the fight against the Colorado potato beetle.
Red beetles have become resistant to chemicals. Before choosing any of them, you should take this into account. To date, the most effective modern drugs: Inta - Vira, Decis, Fufanon, Talstar, Kinmiks and others.
If the flower garden is large and a considerable number of pests have accumulated, you can spray with the means that are used to combat the Colorado potato beetle. The solution must be prepared according to the attached instructions, otherwise the plant can be burned, and the pests will remain alive at that time.
Still, "chemistry" is not one of the best ways to deal with harmful insects, including red beetles. Whatever insecticide you choose, no matter how its merits are advertised, it, in fact, was and remains the poison that carries great harm nature.
In 1996, French scientists initiated large-scale research, which was then carried out in European countries on lilies in the very season of the appearance of the red beetle. More than 1,000 eggs, about 30,000 larvae and many thousands of adult red beetles were delivered to the laboratory for research.
In order to have healthy lily plants in your garden, you need to prepare in advance for protection against small and large pests, including red beetles - firefighters. It is necessary to purchase the necessary drugs and a good sprayer, prepare everything so that you can start the fight for the health of your pets in time. It is important not to forget that the beauty of flowers is in the hands of the owner!

What to do if red bugs eat lily leaves?
IN last years all amateur flower growers who grow lilies have a serious problem. Its cause and other troubles are associated with the mass distribution of voracious red bugs of a large family of leaf beetles, the genus Lilioceris (Lilioceris).
Cute rattle beetles are active and incredibly voracious
We spoil the life of two common species. This is, first of all, onion ratchet, bulbous, or bulbous daylily (L. merdigera). The lily or lily rattle, the lily beetle (L. lilii), known as the "fireman", also causes harm. The pest eats the leaves so much that often only the stem remains from the plant. Then there can be no talk of any flowering.
Last summer, I began to notice these red bugs on the broad leaves of imperial hazel grouse and daylily. They are just looking at these plants. Do not touch and lilies of the valley.
Description of red bugs eating lily leaves
Onion cracker, or bulbous (Lilioceris merdigera), refers to leaf beetles with a bright red body and head. The ratchet has powerful jaws. Her food is not only leaves, but also buds, flowers and even stems of plants of the Liliaceae family.
If you do not destroy the pest, there will be no flowering
In nature, beetles feed on lilies of the valley, so they willingly move to areas located near the forest. They have a varied menu there. The ratchet is known to many as the "lily beetle".
Lily, or lily, ratchet (Lilioceris lilii) is a beautiful beetle, which is sometimes called "peeper beetle" and "fireman". It has an elongated oval red body and a black head. This beetle also willingly "bites" lilies.
Children catch rattles, hold them in their palms or put them in empty matchboxes to hear the faint creak that many rattling beetles (their abdomen) make when threatened.
Onion cracker, or bulbous, came to us from Europe at the end of the twentieth century, when foreign planting material. Important note: these bugs don't bite!
If you do not fight the pest thoroughly, starting in spring, you will have to deal with larvae that appear in May - June from testicles laid on the underside of the leaf. And they will be incredibly hungry. The voracity of the larvae is so great that they are able not only to make holes in the leaves of lilies, but also to destroy them entirely.
In a few days there would be nothing left of the leaf
Last year, I was left with gnawed "stumps" from several lilies that grew behind the fence. It is difficult to notice the larvae, because. they are covered with a nasty greyish-brown mucus. It is needed to scare off potential enemies.
Touching these mucous lumps is very unpleasant.
The next stage of pest development is pupation in the soil (orange pupae). Then a new generation of red beetles appears, which also want to eat. The rattlesnakes hibernate under fallen leaves and start breeding in the spring of the following year.
How to deal with lily eaters?
Most the right way- mechanical, in which the pest must be collected by hand. It is convenient to immediately shake off in a jar of water. Definitely with a lid. The fact is that the rattles are perfectly kept on the surface of the water, quickly moving with their paws. They huddle together and deftly climb onto the back of the bugs that are nearby. After that, they instantly fly out of the bank.
Pests in a jar of water
If there is no container at hand in which to place rattles, then you have to deal with them on the spot, crushing them with your foot.
If I'm in a hurry and can't take a single minute to collect the red bugs, then I just throw them on the ground. Sometimes they fly away, more often they instantly fall to the ground (paws up) and freeze. So I manage to disarm the pest at least for a while.
Of the broad-spectrum insecticides, I would put Sonnet in first place. It acts on the chitinous cover of bugs, destroys their eggs and larvae, and suppresses the ability of insects to produce offspring. The drug is not washed off from plants with water for a long time, therefore it has a long-term protective effect, maintaining activity for up to 30 days. By the way, this drug is considered one of the most effective and safe means of combating even the Colorado potato beetle.
The modern pyrethroid broad-spectrum insectoacaricide "Bifentrin" ("Talstar") copes well with rattles. This drug is moderately toxic to birds, low toxic to humans. It is not recommended to use during the flowering period.
"Aktara", "Aktellik", "Confidor Extra" work well (moderately dangerous substance; cannot be used if there are bees) and INTA-VIR. Plants must be sprayed carefully, from all sides, because. lily pest persistent.
If lilies are grown for cutting, then it is better to use preparations of biological origin. For example, "Fitoverm, KE" and "Bitoksiballin". It is advisable to carry out spraying with an interval of 20 days.
When using any tool, you must study the instructions. It should indicate how many days after treatment the plant can be used. In this case, we are interested in cutting or food plants growing nearby.
On the lilies dark leaves red bugs are usually less
Among the means of struggle there are also biological options. It seems to me that in those years when there were a lot of wasps, the number of rattlers slightly decreased. But do not breed wasps, many of which are dangerous to people. Several species of wasps are known to need bugs (their larvae) to lay their eggs. This method is hardly suitable for amateur flower growers. It is used only by individual industrial enterprises under the close supervision of specialists.

Red fire beetle on lilies
The red beetle is hard to miss on lily leaves. For the scarlet color of the fire engine, these harmful leaf beetles are called the fireman beetle. The lily beetle has a red body, while the head and legs are black. The onion beetle, a close relative of the daylily, has a red-black body, only the antennae and legs are red-black. Lily (lily) and onion red beetles, which look so impressive in the photo, are large garden pests. Red beetles mate on the leaves of hazel grouse and lilies, which then eat the emerging larvae, causing great damage to plants. Read about how to deal with the red lily beetle naturally and with biological control.
scientific name red lily fire beetles - lily rattle (Lilioceris lilii) and onion rattle (Lilioceris merdigera). It is believed that red beetles emit a sharp high-pitched sound when they see danger. To be honest, I have never heard any sounds from lily beetles, although for years I have been regularly collecting them in spring and summer from lily leaves and hazel grouse in my garden.
Adult individuals of the red beetle overwinter, burrowing into the ground near the bulbs of lilies and hazel grouse. In the middle of spring, the mating period begins for firefighters, so beetles clinging to each other can often be seen first on hazel grouses, and then on lilies. The female red beetle lays eggs under the leaves and on the stems of lilies and hazel grouses; the period of laying eggs continues in lily beetles until mid-summer. The larvae hatch after 7-10 days, surrounded by a disgusting gray-brown slime that repels birds and other possible predators. The larvae of the red fire beetle eat the leaves of lilies and hazel grouse and grow rapidly. Grown up larvae burrow into the ground, where they pupate, and reappear on the surface of the earth, starting from mid-summer. Then comes the next stage of eating the leaves of lilies and hazel grouse, as a result of which sometimes only bare stems remain from poor plants. In autumn, a new generation of red lily beetles burrows into the ground, going to hibernation, and in the spring the whole fireman development cycle is repeated again.

Methods of dealing with the red lily beetle firefighter
Physical - manual collection of red fire bug, mulching
If you have only a few lilies and grouse in your garden, like I do, then the best way to deal with the red beetle is manual collection and destruction of adult beetles. It is best to do this in the spring, even before they lay their eggs. Skill is required to collect adult red beetles. the fireman who slipped between his fingers immediately hides and burrows into the ground, from where it is virtually impossible to extract him. Some gardeners bring a small container of soapy water with them, into which they shake off red beetles found on lilies. In the spring, you need to check the greens of hazel grouses and lilies every day to catch daylily beetles before laying eggs.
If the fire beetles were still able to lay their eggs on the hazel grouses and lilies in your garden, then you can collect the eggs of the lily beetle or the larvae themselves at the stage of their maturation (photo above), although this is an unpleasant task. Use thin rubber gloves and tissue paper (such as toilet paper) to collect red beetle larvae.
Mulching (covering) row spacing near lilies and hazel grouses with garden film has proven itself as a means of preventing the red beetle from burrowing into the ground for the winter.
Biological: bacteria against the red fire beetle
Curiously, in the early 2000s, European wasp larvae from the ichneumonid wasp family (a natural predator of eggs and larvae of the red beetle) were successfully introduced into the experimental territory in the northeastern United States. As a result, the population of red beetles has declined significantly over the years.
Ready bio-control agent - gentle on environment Spinosad (Spinosad), containing bacteria that destroy whole line garden pests. The product must be applied in the evening to avoid inhalation by bees.
Chemical: (gentle) pesticides against the red fire bug
Organic gardeners prefer to use mild, natural pesticides based on pyrethrins (substances found in pyrethrum - Dalmatian chamomile that affect nervous system pests). These agents are more effective against red lily beetle larvae than against adult firefighters. Pyrethrins also help against aphids, see our article.
Another mild pesticide against the red lily beetle is neem tree (Azadirachta indica) oil, which is thought to kill the larvae and repel the adult fire beetle. The pesticide is applied in spring and early summer, when the red beetle is most vulnerable, every 5-7 days in a thick layer on the greens of lilies and hazel grouse.
From the means of rigid chemical control from the red beetle, the following are used: karbofos, thiacloprid, acetamiprid, deltamethrin or lambda-cyhalothrin. Use these strong means must be extremely careful, because. along with pests, they will destroy many beneficial insects.

Various insects and diseases not only spoil the appearance of flowers, but can also cause the death of all plants in the flower bed. To keep plants healthy, you need to learn how to correctly identify lily diseases and take appropriate measures to deal with them.
The most common diseases and pests of lilies with treatment methods and photos will be described in this article. From it you will learn about the characteristic signs of diseases, as well as traditional and folk methods treatment.
Lily diseases and their treatment with photos
The fragrant lily has always been the main decoration flower arrangements. They love her for a simple way of planting and unpretentious care, but they often forget that only compliance with the rules of agricultural technology ensures full-fledged healthy flowering.
In addition, the resistance of a crop to diseases depends on the geographical origin of the plant. For example, natives of the tropics have a hard time enduring winter and may even die due to insufficient air humidity. Therefore, plants planted in unsuitable climatic conditions grow weakened, get sick more often and longer and die faster.
Causes
Most often, lilies are susceptible to fungal and viral diseases. So, in thickened plantings or with prolonged cultivation in one place, there is a risk of developing fungal diseases, among which there are (Figure 1):
- gray gil;
- rust;
- Sclerocial rot;
- Root and bacterial rot.
Viral diseases are carried by insect pests or through an infected garden tools. The most common among them:
- Variegation virus;
- rosette disease;
- Mosaic.
Figure 1. The main symptoms of diseases in flowers Let us consider in more detail the diseases of lilies, their symptoms and methods of treatment with a photo.
Symptoms
To start the correct fight against diseases, you need to familiarize yourself with characteristic symptoms each pathology according to the photo and description.
- Gray rot (Botris)
It appears as rapidly growing brown spots on the lower leaves, which soon form large areas of mucous tissue covered with plaque (Figure 2). Affected stems die very quickly, so it is recommended to take preventive measures aimed at preventing the development of this disease.
Ways to deal with gray rot are:
- Preliminary disinfection of bulbs before planting in a solution of foundationol;
- Change the place of planting bulbs every 4-5 years;
- Compliance with the sparsity of landings;
- Implementation of watering in the morning hours in the root method;
- Construction of a protective canopy over the flower bed in case of a rainy period;
- Preventive spraying of seedlings in early spring solution blue vitriol(0.5%), Bordeaux liquid (1%) or copper oxychloride (0.3%).
Figure 2. Symptoms of gray mold When a disease is detected, the solutions are used in turn with an interval of 10 days, the affected parts of the plants are destroyed.
Appears on bulbs with mechanical damage. The disease is most pronounced during storage. Symptoms are yellow-brown spots appearing at the attachment sites of the scales (Figure 3). Subsequently, these spots turn into soft rotten areas, and the bulb disintegrates.
Note: The disease is most active in hot weather with a high level of humidity. The spores of the fungus that causes Fusarium can persist in the soil for about 3 years.
The fight against the Fusarium fungus consists in the release of the bulbs from the affected scales with a mild degree of the disease and in the destruction of the bulbs with a strong defeat.
Figure 3. Signs of Fusarium In addition, the soil is disinfected 2-3 weeks before planting with a solution of 40% formalin (250 ml of the substance per bucket of water) and the soil is sprayed with foundationazole (0.1%), euparen (0.2%), bavistin (0.05% ) in early spring.
- Rust
Spores of the fungus that causes rust can overwinter both in stems and leaves, and in bulbs. Rust, as a disease, is manifested by the appearance of small colorless spots on the leaves, later they turn yellow, and the leaves and stems dry out (Figure 4). The dark growths remaining on them contain a large number of fungal spores that can infect other plants in the spring.
Figure 4. Manifestations of rust Therefore, for preventive purposes, pre-sowing treatment of bulbs and frequent top dressing with the application of potassium-phosphorus fertilizers are recommended. In addition, at the beginning of spring, preventive spraying of seedlings with Bordeaux liquid or copper oxychloride is carried out. When the first signs of the disease are detected, ditan, polycarbacin, cineb are used. If the lesion is still insignificant, then its infected parts are removed and destroyed. In the case of a severe lesion, the entire plant is removed from the site and destroyed along with the bulb.
- sclerocial rot
The first sign is called uneven seedlings in the spring. Bulbs that are lagging behind in growth have a thick white coating at the neck of the bulb or on its bottom. The developing disease leads to the death of the roots and leaves (Figure 5).
Note: Most often, sclerocial rot develops at air temperatures below +13 degrees in conditions high humidity. Therefore, with an increase in temperature and a decrease in humidity, the disease stops its spread.
Figure 5. Symptoms of sclerocial rot Prevention of sclerocial rot is similar to the methods of dealing with fusarium and botrys. Sick plants are removed along with a clod of soil, and foci of infection are treated wood ash or bleach. In addition to lilies, daffodils, tulips, hyacinths, gladioli are also susceptible to this fungal disease, so it is not recommended to plant lilies after these decorative bulbs.
- root rot
In accordance with its name, the disease affects precisely the roots of the plant, as a result of which it begins to lag behind in growth, and then loses buds. A signal of the onset of the disease is the yellowing of the tops of the leaves, which soon passes to the entire stem and leads to its drying out (Figure 6).
To prevent plant diseases with root rot, the following set of protective measures should be carried out:
- Carefully select planting material;
- Pickle the bulbs before planting;
- Disinfect the soil with a solution of colloidal sulfur (0.4%).
Figure 6. Signs of root rot All affected plants must be removed from the flower bed and destroyed to prevent the spread of rot to other crops.
- bacterial rot
Leads to rotting and falling off of leaves and peduncles. The bulbs of the plant are also affected by rotting sunken spots.
To combat this disease, the following procedures are taken:
- Regular inspection of bulbs during storage in order to timely detect and further destroy infected planting material.
- Pre-sowing treatment of the soil and the bulbs themselves.
- Spraying with fungicide seedlings in early spring, and if bacterial rot is detected, such spraying is repeated every decade.
If fungal diseases can be prevented by various preventive measures, then this cannot be said about viral infections. In addition, this type of infection is not only impossible to prevent, but also very difficult to diagnose and treat. Viral infections are transmitted by pests and plant sap through untreated implements. Such diseases manifest themselves in different ways, and the fight against them consists in the destruction of the affected plants. The most widespread viral infections are variegation, rosette and mosaic.
The main symptoms of viral diseases are(picture 7):
- variegation virus causes unusual for lilies, spotted color of the flower. This disease can be carried by aphids, and it is also transmitted through garden tools.
- rosette disease provokes the action of a whole complex of viruses. It is manifested by a delay in the growth of peduncles, deformation of the stem, the formation of leaves irregular shape. The carrier of this disease is the aphid.
- Mosaic- a viral disease that has symptoms similar to botris. In this case, the leaves are covered with oblong spots of pale gray color. The viral mosaic of aphids is also transferred through a garden tool.
Figure 7. Viral diseases: 1 - variegation, 2 - rosette, 3 - mosaic Methods for combating viral diseases include preventive examinations of bulbs placed in storage and the removal of specimens with an unusual discoloration of the aerial parts. Since the mosaic can be transmitted with plant sap through inventory, a set of blades should be used when cutting flowers, which are disinfected after use. It is also necessary to fight aphids by spraying lilies with karbofos or ragora.
Lily diseases: video
If you want to keep blooming lilies in the garden or pots, we recommend that you familiarize yourself with the video, which describes in detail the main diseases, methods for dealing with them, and effective means of prevention.
Asian lilies: diseases
Lilies belonging to Asian hybrids are the most unpretentious, and therefore the most common. They can be grown almost all over the world, even in Alaska.
In cold climates, the flower stalks of the plant are cut at ground level so that they do not rise above the snow cover. However, Asiatic lilies are more susceptible to some fungal and viral diseases than others.
Causes
A fungal disease known as botrys affects flowers in cold weather With high level humidity. Therefore, when choosing a landing site, you should choose a place that is well ventilated.
Rotting of the bottom of the bulb is also caused by a fungus and is called fusarium. The reason for its occurrence is the stagnation of water as a result of poor drainage or its absence, the use of fresh manure as a top dressing, the drying of an earthen coma.
Quite often, lilies are infected with the variegation virus, which is transmitted to them from tulips that previously grew on the site. Therefore, it is not recommended to plant lily bulbs after other bulbs. Insect pests can also be the cause of viral diseases. Fighting them regularly will protect your plants from viruses. Remember that well-groomed plants are much more resistant to various diseases.
Symptoms
How to recognize the onset of the disease in order to provide the plant with the necessary assistance in a timely manner? To do this, you need to know the symptoms of diseases. For example, when affected by gray rot, signs of the disease appear on the leaves in the form of brown spots, which merge into whole foci, passing to the buds (Figure 8).
Figure 8. Manifestations of diseases in Asiatic lilies It is important to know that viral diseases are much more dangerous than fungal ones, because they often proceed in a hidden way, and when the symptoms become visible, it is impossible to save the plant. So, for example, the virus of variegation proceeds. Therefore, having noticed the features and color of the flower that are uncharacteristic for the plant, the shape of the stem, you should immediately get rid of it so as not to infect the entire flower garden.
Treatment
The best way to fight disease Asian lily is prevention. So, to prevent the disease with botrys, it is recommended to shed the seedlings with a solution of copper sulphate, ammonia and soda ash.
Note: To prepare a solution of 1 tbsp. copper sulphate dissolves in 5 liters hot water, and the same amount of ammonia and soda is diluted in 5 liters cold water. Then a solution of copper sulfate is poured into a solution of ammonia and soda.
If preventive measures have not been taken, then for the treatment of gray rot, plants are sprayed with Bordeaux liquid, and in case of severe damage, with foundationazole or phytosporin every 2 weeks. In case of Fusarium disease, it is necessary to dig up the bulbs, rinse them well and soak in the foundation solution for 30 minutes.
Remember that it is impossible to cure viral diseases, therefore, if viral lesions are detected, your the main task- remove and destroy the infected plant as soon as possible in order to save the entire flower garden.
Lily pests and their control
Bulbs of culture contain a large amount of nutrients, therefore they are a delicacy not only for rodents, but also for various insect pests.
They not only weaken plants by eating leaves and bulbs, but are also carriers of dangerous viral diseases. Consider some types of lily pests x and methods of dealing with them.
Lily Pest Control: Red Beetle
red lily beetle appearance similar to a firefighter, and in terms of fertility and gluttony - with the Colorado potato beetle. The adult insect and its larvae eat the leaves, flowers, and bulbs of the plant (Figure 9). Adults appear on flowers as early as April, and if protective measures are not taken, it will be extremely problematic to cope with the larvae that hatch soon.
Figure 9. Larvae and adults of the red beetle Therefore, as soon as red beetle pests appeared on the plants, you should immediately start fighting them. It is best to manually collect and destroy the insects. If time has been lost, it is necessary to spray the plants with any insecticide that is used to control the Colorado potato beetle, for example, actor, confidor, decis.
Oval orange beetles with two dozen points on the elytra are onion leaf beetles. Adults and their pupae overwinter in the soil and come to the surface at the end of April. The onion leaf beetle damages mainly lilies by eating leaves from the edges or gnawing holes in them. The larva of the onion leaf beetle is able to skeletonize leaves (Figure 10).
As preventive measures control, it is recommended to regularly destroy weeds in the flower garden, on which leaf beetles can lay their larvae, collect adults by hand and destroy them, spray plants affected by larvae, chlorophos or an infusion of herbs from wormwood and larkspur.
Figure 10. Flowers affected by the onion leaf beetle To prepare an infusion of herbs, you will need a bucket of finely chopped wormwood or 800 g dried, which is poured cold water and infused for a day, then boiled for half an hour and immediately before spraying it is diluted with water twice. Spraying with wormwood is repeated several times at weekly intervals.
An infusion of larkspur is prepared at the rate of 1 kg of chopped grass per bucket of water. The agent is insisted for 2 days, then filtered and immediately used.
Aphid
Aphids are among those insects that not only harm plants themselves, but are also carriers of viral diseases (Figure 11).
For this reason, this insect must be quickly destroyed in order to prevent its reproduction. In the fight against aphids, Intavir (1 tablet per bucket of water) and Fufanon solution (10-15 ml per bucket) have proven themselves well.
From the video you will learn additional information about lily pests and methods of dealing with them.
Processing lilies in the spring from diseases and pests
Unfortunately, lilies often get sick, they are damaged by many pests. Experienced gardeners know that the best way to fight is prevention and timely assistance. After all, the sooner the disease is detected, the easier it will be to treat, and the more likely it is to save the entire blooming collection. That is why it is strongly recommended to shed the seedlings that have appeared with special solutions. For example, a mixture of soda, ammonia and copper sulfate or Bordeaux liquid and copper chloride.
Figure 11. Lilies infested with aphid colonies In addition, immediately before planting, it is desirable to treat the bulbs with a 0.2% solution of foundationazole or a solution of karbofos (1 tbsp per bucket of water). You can also disinfect the bulbs in a weak solution of potassium permanganate.
Red beetle - malicious pest lily, popularly known as piskun. Does not bite, is not poisonous, does not publish bad smell, safe for humans. In case of danger to his own life, he falls to the ground, tightens his paws. The red bug belongs to the leaf beetle family, feeds on the green part of plants, becomes a provocateur of fungal, bacterial infections.
Who eats lilies in the garden
Two types of pests live in our area - onion red beetles, lily or lily. Outwardly similar to each other, lead an identical lifestyle. The bright red color resembles the color of a fire truck, because of this he was called a fireman. In dangerous situations, the insect begins to make sounds similar to crackling. Due to this feature, they are called squeakers, crackers, ratchet.
Lily beetle of medium size - up to 1 cm in length. The body is stretched most occupies the abdomen, the head is small, black, lowered downwards. Long swirling whiskers, 3 pairs of short, tenacious legs ending in claws. The chest is small. The body is covered with a strong shell. The wings are well developed, insects fly long distances in search of food. A photo of a pisk beetle is presented below.
On a note!
Larvae - caterpillars different size off-white, yellow color with a dark head. There are several stages of development last step pupate. They live together with adults on infected lilies, hazel grouse, lilies of the valley.
Lifestyle, nutrition
The peep beetle is active in the warm season - from May to August. The mating season begins in late spring, larvae begin to appear in June, and by the end of August a new generation of young adults emerges. The lily beetle lives in numerous colonies, prefers lilies different varieties. With a lack of food, it settles on hazel grouses, lilies of the valley, and weeds.
Active during the day, sits motionless on plants at night. The larvae live on the underside of the leaves, hiding from direct sun rays. Some species of birds feed on adult beetles. The main enemies for the larvae are earthen wasps. They lay eggs on the body of a living victim, after a few days the cubs appear, begin to eat it from the inside.
The red beetle has a good appetite. For a few days of living on the plant, the lily begins to wither, get sick, fade. If you do not respond to the problem in a timely manner, the flower dies. The red-backed onion beetle, in addition to lilies, feeds on potatoes, tobacco, onions, and hazel grouse.
The pest of lilies, the red beetle, lives for several seasons. With the onset of cold weather, young individuals burrow into the ground, tolerate frosty winters well, crawl out to the surface in spring, begin to mate, and lay eggs. By the end of August, they die, the young generation, pupae, remains to winter.
reproduction
The mating season begins in May. The female lays her eggs on the underside of lily leaves. Oval, orange, no larger than 1 mm. Incubation period lasts 20 days, then larvae appear - thick caterpillars. The cubs begin to actively feed, grow, pupate in a week, turn into sexually mature adults.
How to deal with red bugs on lilies
What to do if red beetles appear on the lilies depends on the number of pests, personal preferences of flower growers, and the size of the flower bed. Folk, chemical remedies will help save the plant from death.
How to process lilies from red beetles
With a large number of pests, experts recommend the use of insecticidal preparations with contact-intestinal action. You can use any, most often use:
- Decis;
- Inta-Vir;
- Talstar;
- Fufanon;
- Kinmiks.
On a note!
The lily beetle is resistant to other poisons. The solution must be prepared immediately before use. Spray flowers in the evening or early in the morning in dry weather. Pests die in a day, protection remains valid for 20 days.
Physical Methods
The fight against red bugs is ongoing warm season. Every week they inspect the plant, collect pests by hand. On big land plots the procedure is complicated by the fact that, at the sight of danger, the pest falls to the ground, turns its back down, hides its bright back, and merges with the soil.
On a note!
The red-winged beetle prefers certain crops, searches for food by the strong aroma of flowers, finds them several kilometers away. After harvesting, the lilac rattle must be destroyed, or released away from the flower beds.
It is possible to get rid of the red beetle on lilies mechanically in a few weeks, but it is necessary to collect not only adults, but also larvae. Unpleasant creatures hide under the leaves.
Fight with folk remedies
The advantage of the method is safety, environmental friendliness. The principle of operation is based on repelling pests. Lily rattle beetle in its life is guided by the sense of smell. The sharp aroma of some plants clogs the spiracles, makes them fly away. Means with an irritating effect also help to fight the lily beetle. When it comes into contact with the skin of an insect, they cause an unpleasant burning sensation, and death in the esophagus.
How to spray lilies:
- Spices. Mix in equal proportions red, black pepper, mustard, cumin, cinnamon. Pour in soapy water. Spray plants abundantly, giving Special attention underside of leaves. Repeat the procedure every 3 days until the complete disappearance of pests.
- Wood ash. Pests on lilies are red bugs, they are afraid of ash-based products. When it comes into contact with the skin, the paws cause irritation, make them run away from an unfavorable place. The ash is poured with soapy water, the lilies are sprayed, the soil is watered. Repeat the procedure in a week.
- Sagebrush. The concentrated infusion is a natural insecticide. The product repels pests with a persistent smell, and if it gets inside, it kills larvae, adults. Use a fresh, dry potion. Fill with water, insist at least a day. Strain, add laundry soap. Spray lilies. The treatment is repeated every 3 days.
To achieve maximum results, it is recommended to use several methods of struggle at once - chemical, physical, folk. Do not forget to dig up the soil in the flower bed twice a year, periodically inspect the plants. Black bugs on lilies with red sides are also firefighters, but the harm from them is much less. Insects are collected, thrown away from the flower bed.
