Types of fungicides, a review of the most effective drugs and their description. A complete list of plant fungicides What are fungicides

In the process of caring for the garden, it is often necessary to apply fungicides. We are talking about special chemicals that are used to combat pathogens that cause the development of fungal diseases, for example, gray rot, powdery mildew, etc.

Depending on the method of action on pathogenic fungi, several types of fungicides are distinguished: contact and systemic action.

Actions of contact fungicides

When using these drugs, their penetration into plants is excluded. They cover the outer part of the plant; if there is a fungus on the surface of the reproductive and vegetative organs, they are suppressed. All drugs act for a different period, which is determined by the duration of the solution on the surface of the plant. The best results can be achieved if processing at least 3-5 times at intervals of 10-12 days.

A feature of contact fungicides is the local nature of the impact. They are not used to treat diseased plants, they are designed to suppress pathogens located on the surface or directly in plant tissues. Due to the fact that these fungicides are unable to spread to other parts of the plant, such treatment before the formation of fruits excludes penetration into them.

Systemic preparations act somewhat differently: as a result of processing, they penetrate into the internal organs of the plant, spread through the tissues, making changes to the physiological and biochemical processes occurring in the plant organs. As time goes on they decomposition within plants, which ends with the formation of metabolites. In this state, they begin to have a depressing effect on the harmful fungus.

It is believed that the decomposition products that form inside the plants are more harmful than the drug itself. In order to avoid possible complications, it is best to carry out processing in gardens and private households with the help of chemical preparations of precisely contact action. Wherein deadline their use is the period when there will be one month left before the harvest.

Types of fungicides and methods of their application

In gardening stores, fungicides are available in various types: in the shape of powder, suspension, emulsion, highly soluble in water.

Depending on the composition, the following types of fungicidal preparations are distinguished:

Inorganic. Within this group, preparations of 1-4 hazard classes for humans and warm-blooded creatures are distinguished;
Organic. The main component in them are active microorganisms that inhibit pathogenic fungi.

More preferred to use on the summer cottages biofungicides, because in addition to high efficiency, they cause minimal harm to plants.

Chemical fungicides

Often for effective fight With pests, gardeners buy new drugs, especially if they provide high efficiency with a small dose of application. However, doing so is wrong. You can count on good results only if you use proven drugs. Within the group of chemical fungicides that have proven their effectiveness when used for protection during the growing season of various horticultural crops, the following can be distinguished:

Bordeaux liquid;
copper sulfate;
abiga-peak, sun;
oxychome;
cineb;
thiram;
potassium permanganate (potassium permanganate);
soda ash using an adhesive (green soap).

Biological fungicides

In recent years, many biological contact fungicides have appeared on the market. In their manufacture, a slightly different approach is used than in the case of chemical preparations. The main component of biofungicides are active bacteria, whose activity has a depressing effect on pathogens of fungal diseases.

It is more preferable to use biofungicides of contact action, since they do not cause or cause minimal harm to humans, warm-blooded animals, fish and bees. Consumers who are going to use biofungicides at home should pay attention to the following types of preparations:

It is possible to carry out treatment with chemical contact fungicides only before flowering and after harvest. The advantage of biofungicides is that they can be applied throughout the growing season. At the same time, there are also such preparations on sale that can be used at the stage of crop ripening. It should be borne in mind that contact drugs are effective for prevention purposes. If the drug reaches the causative agent of the disease, then this leads to its death. If the plants are already affected by the disease, then they cannot be saved with the help of these drugs.

Rules for working with contact fungicides

Before using a fungicide, you need to take care of your own safety: for this you need prepare closed clothes, rubber gloves and goggles and a headdress. After processing, the clothes are sent to the laundry, and the hands and face must be thoroughly washed with soap and water.

It is necessary to carry out the treatment of plants with a pre-prepared solution. The exception is situations where the instructions require the use of a fresh composition.

In the process of preparing a solution for treating plants, it is necessary to strictly follow the recommendations specified in the instructions, maintaining the optimal consumption rate, taking into account the phase of plant development.

You can use fungicides in the most favorable conditions for this: in the early morning or evening, provided that it is worth dry windless weather.

For the sprayer, it is necessary to select the operating mode for fine spraying. The cloud of solution emerging from it should pour onto the plants from below and from above.

It is forbidden to use chemical fungicides in relation to those plants, the green parts of the above-ground mass of which are planned to be used. For safety reasons, processing of all crops should be carried out before the flowering and fruiting phase.

It is impossible to clean the dishes in which the solution was prepared in reservoirs. Disposal of used pesticides should be carried out only in specially designated areas.

The place where it is supposed to store fungicides and other preparations with chemical composition, should have restricted access. Drugs must be placed in sealed packaging.

If the investigator follows the rules for the use of fungicides listed above, then you can not only prevent the appearance of dangerous pests on the site, but also not harm yourself and the environment.

List of fungicides

Due to the high toxicity of most fungicides on the market today, there must be a good reason for the gardener to use them at home. Before using drugs, it is mandatory to familiarize yourself with the safety regulations for the use of toxic substances.

Oksikh. A drug containing from copper oxychloride and oxadixyl. Belongs to the number of contact systemic fungicides, used for preventive purposes and to suppress diseases of garden and indoor plant crops. Recommended for use in the fight against late blight, macrosporiosis, black bacterial spot, septoria, etc. Non-toxicity makes this drug safe to use.

Preparation of working solution

Processing of plants is carried out only with a freshly prepared solution. First, one third of the volume of water must be poured into the sprayer tank, then start the mixing device and pour the required amount of the drug. After that, the remaining part of the necessary water is poured, the solution mixes well, after which the infected plants are treated with it.

A prerequisite is the purity of the water used to prepare the solution.

The recommended consumption rate is one packet per 2 liters of water. In some cases, it may be necessary to carry out three treatments, but between them it is necessary to withstand a break of 10-14 days. Plants can only be treated with a freshly prepared solution based on the drug oxychom. It can be used as a component for the preparation of complex mixtures.

Advantages of the drug:

operates according to the system-contact principle;
the effect after treatment lasts for two weeks;
lack of toxicity, provided that the treatment is carried out in compliance with the recommended doses;
economy of consumption when used for preventive purposes.

Trichodermin. Included in the group of biological preparations designed to combat fungal and bacterial diseases. The main active component is the spores of the soil fungus Trichoderma lignorum and crushed grain substrate. The drug effectively fights more than 60 types of soil pathogens, which are the cause of many known diseases: root and fruit rot, seed infections, macrosporiosis, fusarium, etc.

The positive effect of the use of the drug is to improve soil fertility, provide plant roots with additional nutrients, increase seed germination.

Application method:

Conclusion

The problem of protecting plants from diseases is relevant for every gardener. To cope with them faster and without consequences, many are used for this chemicals. Fungicides are among the most popular, which demonstrate high efficiency. However, when choosing them, it is necessary to proceed from the position in order to cause minimal harm to the plant. Therefore, preference should be given to those that have the least toxicity. When choosing fungicidal preparations, it is necessary to focus on their recommendations for use. This will help to avoid undesirable consequences after processing.

In the world there is a huge variety of categories of medicinal preparations for plants, each of which has its own characteristics, principle of action and purpose. Given this fact, today we will consider in detail one of these categories, representing fungicides for plants, and talk about all their features, purposes and indications that will be relevant for all gardeners and gardeners.

Fungicides belong to the category of chemical (rarely biological) drugs, the main purpose of which lies in the prevention and treatment of various fungal invasions in the vast majority of plants that exist on our planet.

In addition, the therapeutic effect of fungicides also has a beneficial effect on the treatment and prevention of several other diseases, which is a kind of pleasant side effect.

How do they act?

Fungicides for plants are divided into two categories, each of which has its own principle of action.

So, contact fungicides are not absorbed and do not spread inside the plant, but only envelop it with a thin film, which both protects and also adversely affects existing fungal invasions, causing their death quite quickly.

Systemic fungicides are absorbed and absorbed by plants, and are also effective against both outdoor and indoor fungal diseases, but are not weathered (fungicide cannot wash away rain).

Regardless of which group fungicides belong to, they all have a similar detrimental effect on the fungus, which is expressed in the following points:

Disrupt the process of fungal respiration.
They neutralize the ability of the nucleus of fungal cells to divide, which is more important for systemic fungicides.
Stimulate the formation in the plants themselves of substances that adversely affect fungi. The resulting substances are harmless to humans and plants.
When applied externally, they can destroy the outer parts of the plant affected by the fungus, simultaneously causing necrosis in them. This measure is necessary to prevent the possible spread of fungal spores into healthy plant tissues after the drug is discontinued.
It removes and breaks down pathogenic toxins in the body of the plant, which can provoke the development of both fungal and other diseases, as well as weaken the immune system.
They prevent the production of ergosterol in fungal cells, the suppression of which also leads to the death of fungal invasions.
Suppresses the formation of nucleic acids in the cells of the fungus, which makes their development impossible.
It inhibits energy metabolism in fungal cells, which finally reduces their vital activity to nothing!

Also, there are biological fungicides, the effect on the fungus of which is in the following points:

As mentioned above, fungicides are of chemical and biological origin, and are divided into:

Contact drugs.
Systemic drugs.

In turn, in each group of fungicides there are preparations aimed at treatment, prevention, or treatment and prevention at the same time, which should be taken into account when choosing each individual agent.

When buying a fungicide, remember that the drugs are great at fighting any fungal invasion, but to increase their effectiveness, purchase fungicides that target exactly one of the above fungi, depending on which one appeared on your plants.

In general, today there are more than 14 chemical classes of fungicides, the list of which is presented below:

fungal fungicides;
childrenocarbamates;
imidazoles;
carabamates;
morpholines;
pyrimidines;
triazoles;
organophosphate pesticides, etc.

Instructions for use

Often, fungicides are used in three main ways, such as:

Etching.
Spraying and dusting.
Incorporation into the soil.

Dressing consists in treating seeds or tubers with a fungicide for dressing before planting in order to protect the seeds from fungal infection and prevent their death.

Spraying and dusting consists in treating plants mainly with contact fungicides, which are sprayed onto healthy or damaged plants using a spray gun. As a rule, several such pollinations are carried out per season, starting in spring and ending in autumn.

Application to the soil allows you to rid it of fungal spores and pathogenic microorganisms. Systemic fungicides are used for tillage, so that in addition to disinfecting the soil, they can be absorbed by the root system of the plant.

Fungicides for processing indoor plants are also very popular among the masses, the most effective and safe of which we have presented below:

In the process of caring for plantings, fungicides for plants have to be used. We are talking about drugs that are used for the prevention and control of pathogens - the cause of the spread of fungal diseases. Their pathogens can affect both one crop and a group of plants. In order not to treat the problem, it is better to prevent it and protect the plantings in advance.

The best fungicides for plants

Plant protection specialists are constantly improving the means, creating combined formulations, and paying attention to the immunization of crops. Fungicide preparations are designed to protect vegetable, fruit and indoor plants from pathogenic fungi. The timely use of antifungal agents preserves the health of plantings, increases their decorative effect and productivity, and prevents the occurrence of fungal infections.

What is a fungicide?

Substances of biological or chemical origin are used to prevent and eliminate fungal infections of plants. They are effective for protecting seeds and soil during dressing, the green part of plantings when spraying. Fungicides for plants are divided into:

Fungicides for plants, what are they, what is it? The last decades were marked by an unprecedented growth of viral, bacterial, fungal diseases of all plants. With fungal diseases (late blight, gray rot, other types of rot, powdery mildew, peronosporosis, fusarium, clasterosporosis, root rot, various leaf spots, others) with proper use, fungicides successfully cope - contact, systemic. Bacterial, viral diseases are practically untreatable, no matter what actions gardeners take. All fungicides are divided into preparations of contact and systemic action.

contact fungicides

Contact preparations - such as cineb, polycarbocin, copper oxychloride, sulfur, mancozeb, others - are not able to treat already diseased plants, but reliably protect them from infection. Plants do not develop resistance to them - this is their main advantage. But the term protective effect they do not exceed 10-12 days before the first heavy rain, after which the treatment is repeated.

The multiplicity of treatments for contact fungicides is the largest: from 3 to 6 treatments per season. These drugs almost do not penetrate into the plant, they protect only those places where they are located directly. Therefore, when working with contact fungicides, try to carefully spray not only the upper surface of the leaves, but also the underside of them. Many types of fungi begin to germinate from the underside of the leaves.

Systemic fungicides

Systematicity in plant protection refers to the ability of the active substance to be redistributed from the place of application to other parts of the plant, not only on the surface, but also inside. These drugs protect plants from fungi not only from the outside, but also from the inside. Systemic fungicides are able to have a curative effect, but in the early stages of infection.

Already after 2-6 hours from the moment of treatment, any precipitation (or irrigation) is not able to reduce the effectiveness of such drugs. And the period of protective action remains with them for 2-3 weeks.

However, pathogenic fungi develop resistance to systemic fungicides very quickly. To slow down this process, international crop protection experts recommend using them no more than twice per season on the same crop. And if additional treatments are required, then you need to use drugs or contact action, or a systemic fungicide, but of a completely different chemical group.

Chemical groups of systemic plant protection products (analogues are given in brackets)

Azoles (triazoles) - Vectra (Granite), Skor (Bogard, Dividend), Topaz, Tilt (Bumper), Folicur, Alto, Bytan, Bayleton, Sportak, Impact.
Strobirulins - But, Strobi, Amistar.
Benzimidazoles - Fundazol (Benomyl), Derozal (Colfugo-Super), Tekto (Titusim),
Phenylamides - Apron.
Anilidopyrimidines - Chorus.
Pyrimidinylcarbinols - Rubigan.
Dithianols - Delan.
Phosphonates - Alyett (Alufit).
Phthalamides - Merpan, Folpan.

Like insects, fungal resistance on plants is developed immediately to all fungicides of the same chemical group.

The best options for plant protection are:

alternation of contact and systemic fungicides;
alternation of 2-3 systemic drugs, but from different chemical groups.

For many years, mixed fungicides have been produced, consisting of 2-3 active substances, and they:

both contact and systemic action (Kurzat R. Odram, Acrobat MC, Ridomil Gold MC, Sandofan M8, Tattu, Oxyhom, Pilon, Artemi S, Poliram DF, Arceride, Avixil, others). They are used as contact preparations up to 4 times per season with the concentration of the working solution usually not lower than 0.3-0.4% (30-40 g per 10 l of water). Please note that a lower concentration of solutions leads to poor results. So this is just the case when “you can’t spoil porridge with oil” ... Prepare solutions of fungicides of this group, adhering to the recommendations of the instructions, but it’s better to even make them more concentrated than it is written.
only systemic action, may belong to the same chemical group or to completely different ones. This is done only in order to expand the spectrum of action on harmful fungi. Such fungicides include Mikal, Archer, Ryder, Alto-Super, Falcon, Thanos, and others. They are used no more than twice per season.

Basic rules for using drugs

Spray only in cloudy calm weather, as well as early in the morning - at dawn or in the evening - at sunset. Precipitation falling within 4-6 hours after treatment reduces the effectiveness of many fungicides.
Be sure to use rubber gloves, because. all plant protection products penetrate the skin quite well and are then absorbed into the blood. It is enough to put on a light respirator or bandage on the face.
Try to spray the plants themselves with fungicides, not the soil. A high-quality pneumatic sprayer will help save money, time, and keep you healthy. Therefore, do not save on the purchase of a sprayer.
It is forbidden to treat crops with systemic fungicides that use green stems or leaves as food, as well as radish, radish, daikon, strawberries, currants, gooseberries, cherries, cherries. The last four can only be processed before flowering. Since all these cultures absorb toxic compounds very well, and do not have time to get rid of them until they are eaten, even if the waiting periods are observed.
The working solution is prepared immediately before use, can be stored for no more than a day.
Do not allow any fungicides to enter water bodies, as this leads to the death of all living things in them. Poisons are destroyed faster in the surface layer of the earth, which is not intended for use for vegetable gardens, hayfields, pastures, and playgrounds. The sun, soil microorganisms are the main destroyers, neutralizers of any toxic compounds.
Store fungicides in a dry, dark, preferably frost-free area away from food. All packages must be sealed, as air moisture changes physical properties drugs. The shelf life of biological products is 1-2.5 years, chemical products - 10 years or more, regardless of the expiration date indicated on the container label.
