Fungicides for plants - which drugs are the most effective? Let's get acquainted with fungicides - drugs for combating plant diseases. The best fungicide

Plant fungicides are preparations that are often used to treat the soil to cure various fungal diseases of flowers or other crops. They are also used for prevention.

The word "fungicide" is translated from Latin as "one that kills fungus." Such drugs suppress 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 fungicidal drugs. Depending on their chemical properties, the following are distinguished:

1. Inorganic. Usually contain copper, sulfur, manganese, mercury and other substances. They cannot be combined with many drugs from 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 just need to dissolve the product in a small amount of water. Such preparations can be combined with various pesticides. They are not very stable, so they will persist 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. Medicinal. Also known as eradicating. They destroy the fungus that infects the plants.

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

tillage;
seed dressing;
treating plants during the dormant period;
processing crops during the growing season;
spraying rooms where vegetables and grain are located.

Another group is more convenient - universal fungicides. Such compositions 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 distinguished:

1. Contact. They are also called local. The substances remain on the surface of the plant and provoke the death of fungal cultures upon contact with them. The effectiveness of the treatment depends on several factors: duration of exposure, amount of solution used, chemical resistance, weather, etc.
2. Systemic. They spread within the plant's vascular system and suppress the pathogen. The effectiveness of the drugs depends on the rate of penetration of substances into tissues and their distribution throughout 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, which provoke the death of fungal cultures. Their advantage is that they have a low toxicity rate. Thanks to this, they are becoming increasingly popular.

How to use

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

1. Etching. Before sowing, seeds and tubers need to 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 per season - in spring and autumn. Storage areas 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. It is imperative to adhere to the instructions in the instructions that are available for each product, and always observe 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 causing harm to humans, a number of rules must be followed:

1. Put on old clothes, in which the body will be completely closed.
2. Put a respirator or mask on your face.
3. Wear special protective glasses over your eyes.
4. After processing the plant, be sure to wash your hands with soap (it is better to use laundry soap).
5. Clothes that were worn during processing of plants are not recommended to be worn in the future. It should be washed, ironed and stored in a separate place until the next procedure.

All these measures will prevent poisoning of the body.

The drug “Consento” copes with this task perfectly. This innovative development has a wide spectrum of action.

Firstly, the product has a double effect on the plant:

systemic(drug penetrates into inner fabrics crops to remove the disease);
translaminar(the effect is on the leaves, serves as an intermediate stage between the systemic and surface effect).

“Consento” removes late blight on onions, cucumbers and other crops, accelerates plant growth, and protects against the emergence of new infections. In addition, the drug fights false powdery mildew on and, gray and white rot, dry spotting. "Consento" has the form of a creamy suspension.

The concentrate is sold both in small bottles and in large bottles and canisters up to 5 liters (suitable for owners of large plots). The drug is used for prevention and treatment, regardless of the stage of development of the disease.

The product contains two active components.

First– propamocarb hydrochloride – stops further proliferation of the fungus, disrupting its life processes and membrane.
Second component– fenamidone. This component, penetrating into the plant, causes the fungal spores to cease to form, and late blight does not spread to other plants or its parts. This double effect leads to the death of the fungus.

Plant protection lasts up to 15 days. Thanks to this, you will need to spray the tomatoes less often, which means the consumption of the product is reduced.

TO biological fungicides for plants include "Agat-25K". It acts not only as a protector of plants from diseases, but also helps to increase productivity. The composition has a beneficial effect on the development of plant roots and significantly increases seed germination. It is usually used in gardening, but it can also be treated with this drug as a preventive measure.

The active ingredients of the composition are bacteria and bioactive beings of microbial and plant origin. The release form is a paste of flowing consistency, packaged in 10 g jars. For processing, 1 spoon of the product is dissolved in three liters of water. Plants should be sprayed every 20 days approximately 3-4 times a season.

- contact type of fungicides containing copper oxychloride. The latter, interacting with pathogenic spores, has the ability to secrete active copper, which just inhibits their growth and respiration, which suppresses the predominant amount of proteins important for life in pathogen spores.

She fights effectively bacterial and fungal diseases on technical, decorative, floral and fruit crops Oh. , vines and forest plantations can also be treated with this drug.

Did you know? To determine the level of acidity of the mixture, an iron nail is lowered into it for 3-4 minutes. If, after this time, a red coating of copper appeared on the rod, the proportions were not observed correctly.

Reviews about fungicides are varied, it all depends on the manufacturer, some can perfectly protect plants from fungus both outside and inside the green mass, others can only hide the infection for a while without getting rid of the source of the disease.

How and when to use fungicides for plants, are they harmful or beneficial?

Fungicides are usually used when digging with dry substances, spraying during the growth of green mass of plants, and treating seeds before planting in the ground. You can apply 3 times per season every 5-15 days. The preparations perfectly help plants protect against fungus, are not harmful to birds and bees, but are harmful to animals and people, as they are chemicals.

“Alirin-B” is a biological remedy against rot and fungal diseases of plants in tablets, the consumption rate is 2 tablets per 1 liter of water.

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

Soil free of pathogenic microorganisms, healthy plants in the garden - a guarantee of a full harvest of vegetables and berries, bright colors flower beds (help you!), bent under the weight of the fruits of trees and shrubs. 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 the wide spread of many fungal infections affecting almost all types of fruit, garden and ornamental plants in the country:

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

2. The shortage and high cost of the main source of fertility, manure, until recently, led to its replacement by other suppliers of organic matter in the beds. The green mass of tops, mown grass, fallen leaves brought from the neighboring forest - became the most important organic fertilizers in summer cottages. Along with them, pathogenic microorganisms that cause rot and other infectious plant diseases appear in the soil.

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, Fundazol, Fundazim, Benorad. This is why it is so important to strictly follow the dosage instructions for your medications and change them from time to time.

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

The principle of action of different groups of fungicides is different. Some of them affect pathogens on cellular level, others affect enzymes, while others disrupt the respiration 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 already existing diseases, while others are better for prevention and prevention.

Modern drugs are divided into groups:

Strobilurins

Strobe, Profit Gold, Acrobat MC, Ridomil, Tattu. These drugs are best known as effective remedies against diseases of pome fruit crops - apples, pears, and also for preventing contamination of fruits during storage.

Copper preparations

Copper sulfate, Bordeaux mixture, HOM, Oksikhom, Kurzat, Ordan, Abiga Peak. The versatility of copper-containing products allows them to be successfully used in the garden, vegetable garden, and 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. Storage facilities and greenhouses are fumigated with sulfur to eliminate foci of fungal infections on walls and semi-buildings.

Carboxins

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

Benzimidazoles

Fundazol, Fundazim, Benorad. Preparations of this group are used as seed protectants, they are used to treat fruits before storing them in storage, and they treat berry bushes.

Other

Topaz- a leader in the fight against such an infection as powdery mildew. A special feature of the product is its narrow focus on this disease. Efficiency increases with the preventive start of using Topaz fungicide to prevent disease and 3 repeated treatments every 2 weeks. Effective on all plants susceptible to powdery mildew.
Maksim- a widely known disinfectant among potato growing enthusiasts. Fusarium and other soil-borne rots are destroyed by treating seeds, as well as planting material (tubers, bulbs, rhizomatous shoots) of decorative flowers.
Score and its analogue Rayok- these drugs have a wide spectrum and long-lasting effect. They protect fruit trees from scab, tomatoes from late blight, and black currants from powdery mildew. These fungicides, which, during preventive treatment, quickly penetrate into tissues and are not washed off by rain, are convenient to use to prevent diseases. On stone fruit crops (cherry, plum), Skor and Rayok are used to treat coccomycosis and clasterosporiasis.
Other systemic fungicides: Teldor, Tilt, Byleton, Revus and many others.

Prevention and treatment of plant diseases using phytopreparations-biofungicides

Herbal medicines stand apart from the fungicides. There is a widespread belief among summer gardeners that drugs that are not chemically synthesized, but are of biological origin, cause less harm to garden soil and crops. Let's try to figure out what products for combating plant diseases are marketed under names with the prefix phyto-. There are many such fungicides: Fitosporin, Albite, Fitolavin, Trichodermin, Glyocladin, Alirin-B.

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

Saprophytic fungi are propagated in laboratory and industrial conditions. They prepare 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 specific bacterium. A special feature of these microorganisms is their ability to suppress the development of pathogenic microflora and 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 flower plants.

Application of fungicides against plant diseases, list

strawberries

The widespread spread of viral and fungal diseases has greatly reduced the plantations of everyone’s favorite berry in summer cottages. By sharing planting material with neighbors and buying infected seedlings at 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 industrial technology "Frigo" into amateur gardening. Many summer residents are trying to grow a healthy strawberry culture from seeds.

Treating strawberry beds with fungicides helps in the prevention and treatment of diseases such as various bacterial diseases, 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 harvesting the berries, fungicide treatment must be repeated to prevent the disease next year. Late summer, early autumn, when these diseases are heavily affected, we do at least two treatments. Preparations used on strawberry beds: HOM, Bordeaux mixture, Score, Ridomil.

Fruit trees

The most common disease of the apple tree, which is caused by the proliferation of pathogenic microflora, is scab. The fungus attacks apple trees especially hard during seasons with heavy rainfall. The multiplied pathogen, having overwintered on fallen leaves, is carried by the spring wind and settles on the blossoming buds. Thus, scab spores end up in the ovaries. A diseased tree prematurely sheds damaged leaves and produces a crop of cracked, twisted fruits with corky skin.

A fungicide that has long been used to treat scab on apple and pear trees is Bordeaux mixture. It is diluted 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 above list.

Fruit rot (moniliosis) - dangerous disease, causing serious damage to the crop orchard(, cherry, sweet cherry and others). The source of spread of spores is last year's mummified fruits that overwintered on trees. Monilia spores often settle in cracks in 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 affecting apple and pear trees, in addition to copper preparations, can be treated with strobilurins ( Strobe, Profit Gold, Ridomil and many others).

Stone fruit crops suffer from many infectious diseases - moniliosis, coccomycosis, clasterosporiosis. Infection of cherry trees with pathogens is widespread. The infection quickly spreads throughout the area, infecting trees in neighboring areas. To combat diseases that have reached the epidemic stage, many collective gardening forces summer residents to completely get rid of cherry plantings.

The spread of insidious infections on cherries and plums can be prevented by timely treatment with drugs. Score, Rayok, copper-containing fungicides. To get results, in the summer season you have to resort to spraying three times.

Berry bushes

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

Vague purple spots on annual raspberry stems, where leaf petioles attach, indicate a disease called purple spot. Copper-containing fungicides can treat most fungal pathologies in berry gardens.

American powdery mildew (spheroteca) very often affects black currants and gooseberries, especially old varieties that are not resistant to this disease. A thick white coating appears on the tops of the shoots. The bushes look like they are sprinkled with flour. The leaves curl and stop growing, the young shoots become bent, and the berries fall off before they ripen. In shade and waterlogged places, fungal spores 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 remedies.

Protecting tomatoes from late blight and other dangerous infections

How many enthusiasts, burning with the desire to grow delicious, carefully selected varieties of tomatoes in their gardens, abandoned their experiments, despairing of defeating the insidious late blight. Finding conditions ideal for mass reproduction (warmth and high humidity), the fungal spores instantly spread throughout the beds and greenhouses with tomatoes, not bypassing potato plantings. Their settlement does not stop the temperature drop in August - September. At the same time, other tomato infections may begin: brown spot, macrosporiosis.

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

Tomatoes infected with late blight are treated with fungicides containing copper. Add 50 grams of the drug to 10 liters of water. HOM(copper chloride) or Abiga-Pak. Spraying is carried out with a fine spray, trying to moisten reverse side leaves. When infected with late blight, a whitish coating can be observed (the underside of the leaf), formed by a fungus. Best result In treatment, three-fold treatment gives. The first spraying, as a warning against 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.

Treatment in a cucumber bed

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

For example, Ordan or its equivalent Kurzat diluted at the rate of 50 grams per bucket of water and sprayed on cucumber vines. The waiting period for these drugs (you cannot harvest) is 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 vines 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, ventilating the greenhouse or greenhouse more often, and in the future selecting varieties and hybrids that are resistant to downy mildew.

Decorative garden

Protection from pathogens of fungal infections is required not only for vegetable and fruit crops; decorative garden. Luxurious pine and others coniferous plants may be affected by rust, which cannot be removed without treatment Oxychom.

Rhododendrons, like tomatoes, are affected by late blight. To prevent and treat it, you will need to water the soil. Foundationazole, spraying Order and its analogues.

Many flowering perennials suffer from powdery mildew. First of all, these are autumn asters, delphiniums, peonies, cinquefoil, and roses. In addition to pruning and removing affected parts of plants, they will be helped by spraying with fungicidal preparations ( HOM, Score, Topaz).

Attention is paid to protecting tubers and flower bulbs from diseases during winter storage. Before laying, they are thoroughly dried and treated with Maxim.

Treatment of storage facilities and greenhouses

To prevent late blight and downy mildew in the greenhouses where tomatoes and cucumbers were grown next year, 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, and glass are wiped with a solution of copper sulfate, and the room is fumigated with sulfur preparations. Consumption - 50 grams of sulfur per 1 cubic meter. 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, Oksihom 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 classified as contact fungicides.

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;
garden sulfur.
