Fungicides for plants - which drugs are the most effective? Getting to know fungicides - preparations for combating plant diseases The best fungicide

Fungicides for plants are drugs that are often used for soil treatment to cure flowers or other crops from various fungal diseases. They are also used for prevention.

The word "fungicide" is translated from Latin as "the one that kills the fungus." Such drugs inhibit the development of fungi. The latter are considered the causative agents of various diseases, including powdery mildew, which affects green spaces.

Main types

There are several classifications for fungicides. Depending on their chemical properties, the following are distinguished:

1. Inorganic. Usually contain copper, sulfur, manganese, mercury and other substances. You can not combine them with many drugs of other groups.
2. Organic. Gradually decompose. Heavy metals are not included. This is their main advantage. It is very easy to prepare the solution - you need to dissolve the product in a small amount of water. Such preparations can be combined with various pesticides. They are unstable, so they will remain in the soil from several days to several weeks, after which they are destroyed.

There is another classification of fungicides - according to their effect on pathogens of fungal diseases:

1. Preventive. Also called protective. They are used to prevent the development of fungal diseases.
2. Medical. Also known as eradicators. Destroy the fungus that infects the plants.

Depending on the purpose of use, fungicides are divided into those that serve for:

tillage;
seed treatment;
processing plants during dormancy;
processing crops during the growing season;
spraying rooms where vegetables and grains are located.

More convenient is another group - universal fungicides. Such compounds are used for various purposes, they are suitable for both indoor plants, and for various garden crops, trees and other things.

Depending on how the components are distributed in plant tissues, fungicides are isolated:

1. Contact. They are also called local. Substances remain on the surface of the plant and provoke the death of fungal cultures in contact with them. The effectiveness of the treatment depends on several factors: the duration of exposure, the amount of solution used, chemical resistance, weather, and others.
2. Systemic. They spread within the vascular system of the plant and suppress the pathogen. The effectiveness of drugs depends on the rate of penetration of substances into tissues and their distribution over parts of the plant. Weather conditions have almost no effect.

Some contact preparations also have a deep effect: they will penetrate into the inner layers of the seeds.

There is another classification of drugs:

1. Chemical. Their main active components are chemical compounds.
2. Biological. The main active ingredients are beneficial bacteria that provoke the death of fungal cultures. Their advantage is that they have a low toxicity index. As a result, they are becoming more and more popular.

How to apply

Drugs that have a fungicidal effect are used in different ways:

1. Etching. Before sowing, seeds and tubers must be processed. It can be either a liquid solution or a dry powder.
2. Spraying or dusting. Ground parts of plants are treated with a spray bottle. It is better to carry out the procedure several times a season - in spring and autumn. Storages and greenhouses are also treated in this way.
3. Introduction into the ground. For protection, fungicides are applied to the soil in powder form during digging. They can be dissolved in water and watered with them on the ground. Thanks to this, all fungi will be destroyed.

It is important to properly dilute the product. Be sure to follow the instructions in the instructions that are for each product, always follow the proportions.

You need to prepare a container. It can be a bucket or a tank. Part of the liquid is supposed to warm up. Then pour or pour the substance into water and mix thoroughly. Then add the rest of the water and mix again. Always use only fresh product to fight fungi. After a few hours, the activity of the solution decreases, especially if the fungicide belongs to the biological group.

To prevent fungicides from harming a person, a number of rules must be observed:

1. Put on old clothes, in which the body will be completely closed.
2. Wear a respirator or mask on your face.
3. Put on special goggles for your eyes.

In the fight against numerous infectious agents on country beds the main weapons are fungicides - preparations for the prevention and treatment of plant diseases. Microbiological science offers a whole arsenal of effective drugs, among which you can choose the best one both for the treatment and for the prevention and prevention of plant diseases. Modern fungicides are safe for people, animals and bees, their application gives quick and tangible results. Some drugs have a prolonged period of action, provide long-term plant protection.

The main thing is to figure out how to prevent and, if necessary, cure diseases, choose an effective fungicidal drug, and correctly calculate its dosage.

The following reasons lead to a large spread of many fungal infections that affect almost all types of fruit, garden and ornamental plants in the country:

1. The accumulation of pathogens occurs through infected plant residues. This is how root rot, late blight, fusarium spread. Fungal spores accumulate in the soil where the infected tops are left to winter, and are carried along garden beds along with unripe compost.

2. The scarcity and high cost of the main source of fertility until recently - manure, led to its replacement by other suppliers of organic matter for the beds. The green mass of tops, mowed grass, fallen leaves brought from a neighboring forest have become the most important organic fertilizers in suburban areas. Together with them, pathogenic microorganisms are found in the soil, causing rot and other infectious plant diseases.

3. Incorrect use of drugs that prevent and treat infections, instead of benefit, can lead to the emergence of fungicide-resistant races of microorganisms. Some pathogens develop resistance (addiction) to fungicides, for example, such as Fundazol, Fundazim, Benorad. That is why it is so important to strictly follow the dosage instructions of the drugs and change them from time to time.

Varieties of chemical fungicides for the treatment of infectious plant diseases, their names

The principle of action of various groups of fungicides is not the same. Some of them affect pathogens on cellular level, others affect enzymes, others disrupt the breathing processes of harmful fungi. According to the spectrum of action, some fungicides are narrowly targeted, while others destroy a wide range of pathogenic microflora. Moreover, some are better used for the treatment of diseases that have already arisen, while others are better for prevention and prevention.

Modern drugs are divided into groups:

Strobilurins

strobi, Profit Gold, Acrobat MC, Ridomil, Tattu. These drugs are most famous as effective remedies against diseases of pome fruit crops - apples, pears, as well as to prevent infection of fruits during storage.

Copper preparations

blue vitriol, Bordeaux mixture, HOM, Oksikhom, Kurzat, Ordan, Abiga Peak. The versatility of copper-containing products allows them to be successfully used in the country in the garden, vegetable garden, greenhouse for the treatment and prevention of many diseases.

Sulfur preparations

Thiovit jet, Cumulus, garden sulfur. They are used not only for processing tree bark and pollination berry bushes. Sulfur is fumigated in storage facilities and greenhouses to eliminate pockets of infection with fungal infections on the walls and semi-buildings.

Carboxins

Vitaros, Previcour. Due to the properties of these fungicides, they are used for dressing seeds. This procedure serves to prevent diseases of adult plants. Previkur has proven itself in the fight against various rots and downy mildew.

Benzimidazoles

Fundazol, Fundazim, Benorade. Preparations of this group are used as seed dressings, they practice the treatment of fruits with them before laying them in storage, they treat berry bushes.

Other

Topaz- a leader in the fight against such an infection as powdery mildew. A feature of the remedy is a narrow focus on this disease. Efficiency increases with the preventive start of the use of the Topaz fungicide to prevent the disease and 3 repeated treatments every 2 weeks. Works on all plants exposed to powdery mildew.
Maksim- a disinfectant widely known among fans of growing potatoes. Fusarium and other rots transmitted through the soil are destroyed by dressing seeds, as well as planting material (tubers, bulbs, rhizomes) of decorative flowers.
Speed and its analogue Rayok- these drugs have a wide spectrum and long-term effect. They protect fruit trees from scab, tomatoes from late blight, blackcurrants from powdery mildew. These fungicides, which, when preventively treated, quickly penetrate the tissues and are not washed off by rain, are conveniently used to prevent diseases. On stone fruit crops (cherries, plums), Skor and Rayok are used to treat coccomycosis, clasterosporiasis.
Other systemic fungicides: Teldor, Tilt, Byleton, Revus and many others.

Prevention and treatment of plant diseases using phytopreparations-biofungicides

Phytopreparations stand apart in a number of fungicides. It is widely believed among summer gardeners that drugs that are not synthesized chemically, but that are of biological origin, cause less harm to garden land and crops. Let's try to figure out what means for combating plant diseases enter the market under names with the prefix phyto-. There are many such fungicides: Fitosporin, Albite, Fitolavin, Trichodermin, Gliocladin, Alirin-B.

Oddly enough, mushrooms help reduce the number of harmful fungi in the soil! Scientists call these useful representatives of saprophytic fungi of the genus Trichoderma suppressors. This is what is hidden under unfamiliar and obscure scientific terms.
Mushrooms - saprophytes feed on the remains of the organic matter of the plant and animal world, and also know how to turn the mycelium of harmful pathogens into a nutrient medium for themselves. The term "suppressor" in this case means "suppressor". In addition to trichoderma, this group includes several more varieties of fungi. All of them successfully destroy populations of pathogens in the soil.

Saprophytic fungi are propagated in laboratory and industrial conditions. They are prepared drugs for the treatment and prevention of diseases in the open and closed ground. The most famous are Trichodermin, Gliocladin.

Fungicides of bacterial origin include an equally popular drug - Fitosporin. It includes a live culture consisting of cells and spores of a certain bacterium. A feature of these microorganisms is the ability to suppress the development of pathogenic microflora, enhance plant immunity. Phytosporin is a fungicide with a wide range of applications. It is used to prevent and cure diseases of potatoes and tobacco, root crops, cabbage, tomatoes, black currants, and flowering plants.

Application of fungicides against plant diseases, list

strawberries

The wide spread of viral and fungal diseases has greatly reduced the plantations of everyone's favorite berries in summer cottages. By sharing planting material with neighbors, buying infected seedlings in the markets, gardeners contributed to the acquisition of healthy garden strawberries became almost impossible. They tried to save the situation with the improvement of planting material by introducing the Frigo industrial technology into amateur gardening. Many summer residents are trying to grow a healthy strawberry culture from seeds.

Treatment of strawberry beds with fungicides helps in the prevention and treatment of diseases such as a variety of bacterioses, spotting, rot, and powdery mildew. It is necessary to fight with diseases in all periods of vegetation of plants.

The first sprayings begin as soon as the leaves start to grow. Repeated treatments are done every 10 days until mass flowering. At the stage of fruit set and before harvesting, the application of drugs is stopped. After picking the berries, the fungicide treatment has to be repeated to prevent the disease next year. The end of summer, the beginning of autumn, when these diseases are severely affected, we do at least two treatments. Preparations used on strawberry beds: HOM, Bordeaux mixture, Speed, Ridomil.

Fruit trees

The most common disease of the apple tree, which leads to the reproduction of pathogenic microflora, is scab. The fungus infects apple trees especially strongly during seasons rich in heavy rains. The multiplied causative agent of the disease, having overwintered on fallen leaves, is carried by the spring wind and settles on the blossoming buds. Thus, scab spores fall into the ovaries. A diseased tree sheds damaged leaves prematurely and yields cracked, twisted fruits with corky skins.

A fungicide that has long been used to treat scab on apple and pear trees is Bordeaux mixture. It is bred for the so-called "blue spraying" in the following proportion: 800 grams of slaked lime and 600 grams of copper sulfate are added to 20 liters of water. The old recipe can be replaced with modern copper-containing drugs from the list above.

Fruit rot (moniliosis) - dangerous disease causing severe crop damage orchard(, cherry, sweet cherry and others). The source of the spread of spores is last year's mummified fruits that overwintered on trees. Monilia spores often settle in the cracks of fruits affected by scab. Copper-containing fungicides are also used to prevent and treat the disease.

Brown leaf spot, stem rot, and many other infections that affect apple and pear trees, in addition to copper preparations, can be treated with strobilurins ( strobi, Profit Gold, Ridomil and many others).

Stone fruit cultures suffer from many infectious diseases - moniliosis, coccomycosis, clasterosporiasis. Infection with pathogens of cherry trees is widespread. The infection quickly spreads around the area, infecting trees in neighboring areas. Many collective gardening, in order to combat diseases that have passed into the epidemic stage, force summer residents to completely get rid of planting cherries.

It is possible to prevent the spread of insidious infections on cherries and plums with the help of timely treatment with drugs. Speed, Rayok, copper-containing fungicides. To get the result, and the summer season, you have to resort to spraying three times.

berry bushes

Often, brown and yellowish depressed spots can be observed on the stems and leaves of black currant. The leaves curl up, dry out and fall off. Most likely, the plant is affected by anthracnose. Gooseberries can also be from this disease. Spores of another fungus, the intermediate host of which is sedge, causes a disease of goblet rust. Its bright hallmark- spore pads on leaves, painted orange.

Blurry purple spots on one-year-old raspberry stems, at the attachment points of leaf petioles, give out a disease called purple spot. Copper-containing fungicides cope with the treatment of most fungal pathologies in berries.

American powdery mildew (sferoteka) very often affects blackcurrants and gooseberries, especially old varieties that are resistant to this disease. An abundant white bloom appears on the tops of the shoots. The bushes look like sprinkled with flour. The leaves curl, stop growing, young shoots are bent, the berries, not ripe, fall off. In the shade and waterlogged places, the spores of the fungus are especially strong.

Since the mycelium of the spheroteca does not live in the soil, but on the shoots of berry bushes, before treating with fungicides, all visible to the eye the affected parts of the plants are cut out and burned. Used for treatment Fundazol, Topaz, herbal medicines.

Protecting tomatoes from late blight and other dangerous infections

How many enthusiasts, burning with the desire to grow delicious, carefully selected tomato varieties in their garden, abandoned their experiments, desperate to defeat the insidious late blight. Once in ideal conditions for mass reproduction (warmth and high humidity), the spores of the fungus instantly spread through the beds and greenhouses with tomatoes, not bypassing potato plantings. Their resettlement does not stop the drop in temperature in August - September. In parallel, other tomato infections may begin: brown spot, macrosporiosis.

The first signals of the appearance of phytophthora on tomatoes are small dark dots on the stems. Gradually, their area increases until it turns into spots. Brown. The same damage appears on the leaves. At first, phytophthora does not appear on the fruits in any way, they seem healthy. But the destructive activity of the fungus goes under the skin of the fruit, and soon depressed brown spots appear on them.

Phytophthora-infected tomatoes are treated with fungicides containing copper. In 10 liters of water, add 50 g of the drug HOM(copper oxychloride) or Abiga-Pak. Spraying is carried out with a fine spray, trying to moisten reverse side leaves. When infected with phytophthora, a whitish coating can be observed (underside of the leaf), fungal. Best result in the treatment gives a triple treatment. The first spraying, as a warning of the disease, should be done as early as possible - a couple of weeks after planting the seedlings.

Daily inspection and removal of affected parts of plants, a short-term increase in temperature in the greenhouse to 55-60 degrees, reducing watering and maintaining a dry microclimate can help in the fight against late blight. There is a known way to save tomato fruits infected with spores, but not yet damaged - for 3 seconds, immerse them in water heated to 60 degrees, then dry and store laid in one row.

Cucumber garden treatment

The most famous and most ruthless enemy of cucumber vines on suburban area- downy mildew. Another name for the disease is downy mildew. The first signs - characteristic spots on the leaves, require immediate treatment. The most effective for the prevention and treatment of disease treatment with copper preparations.

For example, Ordan or its equivalent Kurzat bred at the rate of 50 grams per bucket of water and cucumber vines are sprayed. The waiting period for these drugs (you can not harvest) - 5 days. As a result of the treatment of cucumbers with copper-containing preparations, other fungal diseases are also prevented - olive blotch, anthracnose. The same treatments are useful for preventing diseases in plantings of other pumpkin plants - zucchini, squash, pumpkin.

An additional obstacle to the development of pathogenic fungi will be the raising of cucumber lashes on trellises, which will save them from contact with the soil, where spores of infectious agents are located. For prevention, it is worth thinning out the plantings of cucumbers, ventilate the greenhouse or greenhouse more often, and in the future select varieties and hybrids that are resistant to downy mildew.

decorative garden

Protection against pathogens of fungal infections is required not only for vegetable and fruit crops, it also suffers ornamental garden. Luxurious pine and others coniferous plants rust can hit, which cannot be dealt with without treatment Oxychome.

Rhododendrons, like tomatoes, are affected by phytophthora. For its prevention and treatment, watering the soil will be required. Fundazol, spraying Ordan and its analogues.

Many flowering perennials suffer from powdery mildew. First of all, these are autumn asters, delphiniums, peonies, cinquefoil shrubs, roses. In addition to pruning and removing the affected parts of plants, spraying with fungicides will help them ( HOM, Speed, Topaz).

The protection of tubers and flower bulbs from diseases is given attention during winter storage. Before laying, they are thoroughly dried and treated with Maxim.

Storage and greenhouse processing

To prevent the disease next year with late blight and peronospros in greenhouses where tomatoes and cucumbers grew, they are treated with fungicides. Work is carried out before the onset of cold weather, removing plant debris and digging up the soil. The walls, frames, glass are wiped with a solution of copper sulfate, the room is fumigated with sulfur preparations. Consumption - 50 grams of sulfur per 1 cu. m. greenhouses. Don't forget to process garden tools, pots, seedling boxes and other similar equipment.

In a similar way, preventive work is carried out in cellars and cellars before laying a crop in them for the winter. Before processing with copper sulfate and burning sulfur, the storage facilities must be dried.

Safety precautions for use

Knowing that most of drugs to combat infectious plant diseases does not pose a serious danger to warm-blooded animals and humans, traditional individual protective measures should be taken during treatments - wear closed shoes and clothes, and a mask will not interfere. Most fungicides are safe for bees and other insects, but they can destroy beneficial microorganisms and thus disturb the biological balance. Some types of preparations transmit an unpleasant odor to the soil and plants; if diluted incorrectly, they can cause damage to leaf tissues (burns).

The choice and use of fungicides should be approached with awareness of responsibility, so that instead of benefit, not only damage the future crop, but also the surrounding nature.

Most gardeners throughout their practice have repeatedly encountered fungicides, and in this article we will reveal the focus of these funds, as well as their various classifications in more detail. The term fungicide consists of two Latin words, one of which is translated as a mushroom, and the second is a verb in the present tense "I kill." From this it is easy to conclude that horticultural fungicides are used to combat (or prevent) all kinds of fungal diseases. There are a great many different fungicides designed for soil, seeds, plants themselves, and so on. Today we will talk about how to choose and apply fungicides for plants correctly.

At the moment, there are a large number of classifications of fungicides based on the active substance, chemical properties and the nature of their action. Of course, within the framework of one article, we will not be able to outline the entire range of drugs and their features, so we will focus on the main and most significant points.

Active substance

Depending on the dominant active substance, modern fungicides are divided into several main groups.

Copper preparations

Fungicides containing copper in their composition include such famous and commonly available products as Bordeaux mixture and copper sulfate. This group also includes Kurzat, Oxyhom and Ordan. Such products have a universal status and can be used both for soil cultivation and for processing plants, whether it is a greenhouse, pot or open ground. Most copper preparations are fungicides of contact action.

Sulfur preparations

Sulfur-containing fungicides have proven effective on tree bark and berry bushes. However, in reality, the scope of such funds is much wider - they can be used to successfully fumigate storage areas for fruits and planting material, thereby preventing the growth of fungi that claim to be on cellar walls.

Sulfur preparations include:

cumulus;
thiovit jet;
sulfur garden.
