Fungicidal preparations. Fungicides for plants - description and instructions for use. The product contains two active ingredients

When caring for a garden, you often have to use 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 and etc.

Depending on the method of influencing 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 prevented. They cover the outer part of the plant; if the reproductive and vegetative organs of the fungus are present on the surface, they are suppressed. All drugs are effective for different periods, which is determined by the length of time the solution remains on the surface of the plant. The best results can be achieved if you carry out processing at least 3-5 times at intervals of 10-12 days.

A feature of contact fungicides is the local nature of the effect. They are not used to treat affected 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 fruit formation prevents penetration into them.

Systemic drugs act somewhat differently: as a result of processing, they penetrate into the internal organs of the plant, spread through the tissues, introducing changes in the physiological and biochemical processes occurring in the plant organs. Over time, their decomposition inside plants, which ends with the formation of metabolites. In this state, they begin to have an inhibitory effect on the harmful fungus.

It is believed that the decomposition products that form inside the plants are more harmful than the drug itself. To avoid possible complications, it is best to carry out treatment in gardens and private farms using contact chemicals. Wherein deadline their use is the period when there will be one month left before harvest.

Types of fungicides and methods of their application

In gardening stores, fungicides are offered in various forms: powder, suspension, emulsions, highly soluble in water.

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

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

More preferable to use biofungicides in summer cottages, because in addition to being highly effective, they cause minimal harm to plants.

Chemical fungicides

Often, to effectively control pests, gardeners buy new drugs, especially if they provide high efficiency with a small dose of use. However, it is wrong to do this. Count on good results This is possible only if proven drugs are used. As part of a 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 mixture;
  • copper sulfate;
  • abiga-pik, sun;
  • oxychome;
  • zineb;
  • thiram;
  • potassium permanganate (potassium permanganate);
  • soda ash using adhesive (green soap).

Biological fungicides

In recent years, many contact biological fungicides have appeared on the market. In their manufacture, a slightly different approach is used than in the case of chemicals. The main components of biofungicides are active bacteria, the activity of which has an inhibitory effect on pathogens of fungal diseases.

It is 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 planning to use biofungicides at home should pay attention to the following types of drugs:

Treatment with chemical fungicides of contact action can only be carried out before flowering begins and after harvest. The advantage of biofungicides is that they can be used throughout the growing season. At the same time, there are also drugs on sale that can be used at the stage of crop ripening. It should be borne in mind that contact-acting drugs are effective for preventive purposes. If the drug reaches the causative agent of the disease, 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 glasses and a hat. After finishing the processing, the clothes are sent for washing, and hands and face must be thoroughly washed with soap.

Plants must be treated with a pre-prepared solution. The exception is situations when the instructions prescribe the use of 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.

Fungicides can be used in the most favorable conditions for this: early morning or evening, provided that it is dry, windless weather.

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

It is prohibited to use chemical fungicides on those plants whose green parts of the aboveground mass are planned to be consumed. For safety reasons, processing of all crops should be carried out before the flowering and fruit set phase.

Do not clean the containers in which the solution was prepared in bodies of water. Disposal of used pesticides should be carried out only in specially designated areas.

The place where fungicides and other preparations are supposed to be stored chemical composition, must have limited access. Drugs must be placed in sealed packaging.

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

List of fungicides

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

Oksikhom. A drug consisting from copper oxychloride and oxadixyl. It is a contact systemic fungicide and is 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

Plants are treated only with freshly prepared solution. First, you need to pour one third of the volume of water into the sprayer tank, then start the mixing device and pour the required amount of the drug. Afterwards, the rest of the required water is poured in, the solution is mixed 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 a gap of 10-14 days must be maintained between them. Plants can only be treated with a freshly prepared solution based on the drug oxychome. Can be used as a component for preparing complex mixtures.

Advantages of the drug:

  • operates on 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;
  • cost-effectiveness when used for preventive purposes.

Trichodermin. Included in the group of biological drugs 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 the development of many known diseases: root and fruit rots, seed infections, macrosporiosis, fusarium, etc.

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

Application method:

Conclusion

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

Fungicides, the list of drugs of which will be described below, are means used in crop production to combat plant diseases that are caused by protozoan fungal microorganisms and non-spore-forming bacteria. Any preparations that are used to protect plants from various diseases and pests are called pesticides. Fungicides are one of their varieties. The name is based on 2 Latin words: fungus - mushroom and caedo - to kill.

For those involved in any type of crop production, from farmers and agronomists to amateur flower growers, it is important to be able to choose the right drug. The list of drugs will help you choose the most suitable remedy for the prevention and treatment of plants in crop fields, in the garden or vegetable garden, as well as for indoor flowers.

Classification of fungicides

Depending on the composition, these drugs are divided into:

  • biological fungicides;
  • chemical.

Biological fungicides contain certain types of bacteria, fungi or components of plant origin that have an active antifungal effect. Organic fungicides are easy to use, have little toxicity to insects and warm-blooded animals, and can be used in combination with other herbicides. But the effect of their action is relatively short-lived - from several days to a month. Preparations of this type have gained wide popularity among summer residents and gardeners.

Chemical, or inorganic, fungicides consist of various chemical compounds that have a more pronounced fungicidal effect. They are divided into:

  • copper-containing (for example,);
  • sulfur-containing (colloidal sulfur, Tiovit Jet);
  • iron containing ( inkstone);
  • containing compounds of other elements that have a fungicidal effect.

Chemical organic fungicides, such as carbamates ( Consento, Tattu), dithiocarbamates ( Acrobat, Bogatyr), morpholines ( Cabrio Duo), imidazoles ( Mirage) and others. The effect of using chemical fungicides is more obvious and long-lasting, but these drugs can cause damage to both plants and animals. In addition, they pollute the soil for a long time.

Various fungicides remain on the surface parts of the plant or are able to penetrate into the internal tissues. Depending on this, they are divided into

  • contact;
  • systemic.

Contact - form a surface film on plants and actively influence fungal infection only with direct contact.

Systemic fungicides, after contact with the surface, penetrate all tissues of the plant and destroy the pathogenic fungus in any part of it.

Fungicides for plants are produced in the form of powders, tablets, suspensions and concentrated solutions. Each preparation is accompanied by instructions that must be strictly followed when preparing the solution or while spraying the powder. The fungicidal effect of biological preparations is most pronounced in freshly prepared solutions, so they must be used immediately after preparation. Chemical fungicides should also not be stored to avoid poisoning pets or children.

There are preparations for treating soil against fungi that can live in the soil. These fungicides in powder form are poured into the ground when digging it or dissolved in water and applied during watering. Some preparations are used to treat seed material and tubers before sowing. And, of course, the most large group fungicides are used to treat the green parts of plants during the period of active growth. During the season, several preventive sprayings are usually carried out.

Fungicidal preparations are also used to prevent damage to grain or vegetables by fungi during storage in vegetable warehouses or granaries. Universal remedies have been developed that can be used both for the prevention and treatment of mycoses. IN different periods During the growing season, it is recommended to use certain types of fungicides.

Principles of drug selection

When working with fungicidal preparations, it is imperative to observe personal safety measures. You can prepare the solution only with rubber gloves. The respiratory tract must be protected with a respirator or cotton-gauze bandage. Eye protection is provided by glasses.

The choice of antifungal agent must be made taking into account the area of ​​treatment, the types of plants being treated, the degree of toxicity, and the extent of damage to plants and soil. It is worth listening to the advice of agricultural technicians, gardeners and gardeners, and amateur flower growers. Because many types of pathogenic fungi can develop resistance to a particular chemical, medications must be changed from time to time to ensure their effectiveness.

It is used to restore beneficial soil microflora after the use of toxic pesticides. Suitable for all types of garden crops and indoor plants.

Conclusion and conclusions

Now it has become clear what fungicides are, but before using the selected or recommended drug, it is very important to carefully study the instructions. It is necessary to carefully observe all proportions when diluting. Otherwise, many drugs can cause significant harm to plant crops instead of benefit. When working with chemicals, you should protect yourself with rubber gloves, safety glasses and a respirator.

Throughout the growing season, tomatoes are attacked by various fungal diseases. Fungicides will help prevent the development of the disease or cure plants. Chemical manufacturers have produced a large number of drugs, but not all are effective. What fungicides will allow you to quickly cope with fungal diseases?

What are fungicides, their classification

From Latin, “fungicide” is translated as “mushroom” and “kill.” That is, fungicides are substances that are aimed at suppressing and destroying fungi of various origins. Fungal spores are the causative agents of most diseases that infect tomatoes. Depending on the criterion, fungicides are divided into types:

General division of drugs:

  • chemical origin. To destroy fungi, toxic chemical compounds are used, which quickly eliminate the symptoms of the disease;
  • biological origin. The preparations consist of 90% beneficial living microorganisms that destroy harmful fungi. Biological fungicides are low toxic.

Depending on the properties:

  • inorganic. The composition contains compounds of various heavy metals that block the access of oxygen to fungal spores. Most often found in preparations are: manganese, mercury, sulfur, nickel, copper, iron;
  • organic - harmless to environment drugs that quickly decompose in the soil.

Depending on the direction of action:

  • preventative, which prevent the development of diseases;
  • eradicating fungal spores. Used when the plant is already infected.

The most effective drugs

In order not to waste energy searching for effective fungicides, here is a list and short description the most effective fungicides of chemical and biological origin for the treatment of tomatoes.

Quadris

Fungicide wide range actions. Available in the form of a suspension. It is based on the chemical substance azoxystrobin. The drug will save tomatoes from: late blight, powdery mildew, alternaria. The effect occurs an hour after processing the tomatoes. When a substance gets on fungal spores, it completely blocks access to oxygen, which leads to their death. The effect after spraying lasts up to 3 weeks. To treat 1 m² of plantings, 800 milliliters of solution are needed. The working mixture is prepared using 5 liters of water and one ampoule of the substance (6 ml).

Processing is carried out at intervals of 10-12 days. Preparation of a solution for spraying: dissolve 20 milliliters of the drug in a bucket of water.

The effectiveness of chemical and biological preparations has been tested over years of use. For prevention, choose biological agents. But in case of extreme manifestations of the disease, it is better to use chemicals, the action of which will quickly get rid of the disease.

Recent decades have indeed been marked by an unprecedented increase in viral, bacterial, and fungal diseases of all cultivated plants without exception. Bacterial and viral diseases are practically untreatable, no matter what actions gardeners take. With fungal diseases (late blight, gray rot, other types of rot, powdery mildew, downy mildew, fusarium, clasterospora, root rot, various leaf spots, others) when used correctly, fungicides - contact, systemic.
Fungicidal substances (from the Latin “fungus” - mushroom and “caedo” - I kill), chemical substances capable of completely (fungicidal) or partially (fungistatic) suppressing the development of plant pathogens and used to combat them; one of the groups of pesticides.

Fungicides are classified:
Depending on the chemical properties
they are inorganic (sulfur compounds - lime-sulfur decoction, ground and colloidal sulfur; copper - copper sulfate, copper oxychloride; mercury - mercuric chloride) and organic.
Depending on the effect on the pathogen fungicides are divided into preventive or protective (prevent infection of the plant or stop the development and spread of the pathogen at the site of infection before infection occurs, suppressing mainly its reproductive organs - most fungicides), and medicinal or eradicating (act on the mycelium, reproductive organs and overwintering stages of the pathogen, causing their death after infection of the plant).
Nature of use fungicides are also different: seed protectants (used to combat diseases whose pathogens are spread with seeds or are in the soil), preparations for soil treatment (destroy soil pathogens of plant diseases, especially effective in greenhouses), fungicides for treating plants during the dormant period (they destroy the overwintering stages of the pathogen, are used in early spring before buds open, late in autumn and winter), fungicides for treatment during the growing season (mainly preventative preparations used in summer), for spraying and fumigation of storage facilities, in particular granaries and vegetable storage facilities.
According to the nature of distribution within plant tissues fungicides are contact (local) and systemic (intraplant).
Contact fungicides
Contact fungicides, when applied to plants, remain on the surface and cause the death of the pathogen upon contact with it. Some of them have a local deep effect, for example, they are able to penetrate the outer shells of seeds. The effectiveness of contact preparations depends on the duration of action, the amount of fungicide, the degree of retention on the treated surface, photochemical and chemical resistance, weather, etc.
Contact drugs - such as zineb, polycarbocin, cuprous oxychloride, sulfur, mancozeb, Bordeaux mixture, 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 their period of protective action does not exceed 10-12 days before the first heavy rain, after which the treatment is repeated. The frequency of applications for contact fungicides is the highest: from 3 to 6 applications per season. These drugs almost do not penetrate inside the plant, protecting only those places where they are located directly. Therefore, when working with contact fungicides, try to carefully spray not only the surface of the leaves, but also their underside, since many types of fungi begin to germinate precisely from the underside of the leaves.
Systemic fungicides
Systematicity in plant protection means the ability of the active substance to be redistributed from the place of application to other places, parts of the plant, not only on the surface, but inside the plant. Systemic fungicides penetrate into the plant, spread through the vascular system and suppress the development of the pathogen due to direct action on it or as a result of metabolism in the plant. Their effectiveness is mainly determined by the speed of penetration into plant tissue and to a lesser extent depends on meteorological conditions.
These drugs protect plants both outside and inside. Systemic fungicides can have a therapeutic effect, but in the early stages of infection. Within 2-6 hours from the moment of treatment, any precipitation (or watering) is not able to reduce the effectiveness of such preparations. And their protective effect lasts for 2-3 weeks. However, pathogenic fungi very quickly develop resistance to systemic fungicides. To slow down this process, international experts on plant protection products 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 either of contact action, or a systemic fungicide, but of a completely different chemical group.
Chemical groups of systemic plant protection products (analogs are given in parentheses)

Like insects, fungi on plants develop resistance to all fungicides of one chemical group at once.

The best plant protection options are:
alternating contact and systemic fungicides;
alternating 2-3 systemic drugs, but from different chemical groups.

They have been produced for many years mixed fungicides, consisting of 2-3 active ingredients, and they are:
simultaneously contact and systemic action (Kurzat R. Odram, Acrobat MC, Ridomil Gold MC, Sandofan M8, Tattu, Oksihom, Pilon, Artemi S, Poliram DF, Artserid, 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 liters of water). Please note that lower concentrations of solutions lead to poor results. So this is exactly the case when “you can’t spoil the porridge with oil”... Prepare solutions of fungicides of this group, following the recommendations of the instructions, but it is even better to make them more concentrated than 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.

Currently time is running active development and production of so-called biological fungicides. Their fundamental difference from chemical fungicides is their non-chemical effect on the pathogen; for example, bacterial preparations contain a certain set of bacteria that can cause the death of a number of types of pathogenic fungi.
There are a lot of types of biological fungicides, the main ones are: Fitosporin, Barrier, Zaslon, Fitop, Integral, Baktofit, Agat, Planzir, Trichodermin. Biological fungicides are characterized by low toxicity and high efficiency.

1. Spray only in cloudy, windless weather, as well as early in the morning - at dawn or in the evening - at sunset. Precipitation within 4-6 hours after treatment reduces the effectiveness of many fungicides.
2. 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 wear a light respirator or bandage on your face.
3. With the systematic use of the same fungicides, their effectiveness may decrease due to the formation of persistent races of the pathogen. To prevent this phenomenon, it is necessary to strictly observe the dosage of the drug and alternate the fungicides used. Due to great value F. for Agriculture their production is constantly increasing.
4. Try to spray the plants themselves with fungicides, not the soil. A high-quality pneumatic sprayer will help save money, time, and preserve your health. Therefore, do not save on buying a sprayer.
5. It is prohibited to treat with systemic fungicides all green or other crops that use green stems or leaves for food, as well as radishes, daikon, strawberries, currants, gooseberries, cherries, cherries (the last four can be processed only before flowering) , since all these crops absorb toxic compounds very well, they do not have time to get rid of them before they are consumed, even if the waiting periods are observed.
6. The working solution is prepared immediately before use and can be stored for no more than a day.
7. Do not allow any fungicides to get into water bodies, as this leads to the death of all living things in them. Poisons are destroyed more quickly in the surface layer of soil, which is not intended for use for vegetable gardens, hayfields, pastures, and playgrounds. The sun and soil microorganisms are the main destroyers and neutralizers of any toxic compounds.
8. Store fungicides in a dry, dark, preferably frost-free room away from food products. All packages must be sealed, as moisture in the air changes physical properties drugs. The shelf life of biological products is 1-2.5 years, chemicals - 10 years or more, regardless of the expiration date indicated on the container label.

Fungal diseases- This is enough serious problem any gardener. If you discover that your plant is infected with a fungus, you need to take immediate action, otherwise it will be extremely difficult to save the plant. This may indicate gray coating on the leaves of the plant. In this case, special preparations come to the aid of all gardeners - fungicides. What are fungicides, what they are, how to use them - we will tell you in this article.

Traces of leaf damage by a fungal disease

What is a "fungicide"?

First you need to figure out what it is. Fungicides- These are chemical preparations for treating plants; they belong to a large group of pesticides. Translated from Latin language"fungicide" means "kills fungi." They suppress the development and destroy fungi harmful to plants.

How fungicides work is still not known exactly. The vast majority of these drugs act directly on fungi and their spores, disrupting their normal life processes. Some fungicides disrupt the reproduction processes of fungi, some block the synthesis of proteins and other substances necessary for the life of the fungus, and some disrupt the normal process of fungal cell division.

What types of fungicides are there?

There are many different classifications of fungicides. All drugs according to the production method are divided into chemical and biological. The former are produced artificially from chemical compounds. And the second group is made on the basis of live bacteria that are pathogenic for fungi. The advantage of biological ones is that they are less harmful and toxic compared to chemical ones. It is because of this benefit that natural fungicides are often used by gardeners.

Another one classification of fungicides- according to the mechanism of action. There are two groups of fungicides:

— preventive (they protect plants from harmful fungi);

- medicinal (treat sick plants).

Leaves affected by fungus

Depending on the active ingredients, the composition contains organic and inorganic fungicides.

Inorganic fungicides contain salts of sulfur, copper, iron, potassium, manganese and other substances.

Organic fungicidal products are based on organic matter. They have a number of advantages: such preparations do not contain heavy metals and other harmful chemicals, are easily decomposed by soil inhabitants and are well combined with other pesticides. But organic fungicides also have negative sides- they are not durable and are very quickly washed out of the soil. They are also not particularly effective and sometimes they are not enough to cure a diseased plant. On the contrary, their inorganic “brothers” act for quite a long time and differ quick action and efficiency.

Fungicidal preparations are used for various purposes. They can be used to treat the plants themselves directly (during the growing season or dormancy), to treat seeds before planting for prevention, and they can also treat the soil. But there are also combined preparations that are suitable for complex treatment of seeds, adult plants, and soil.

Different fungicides have different localization on the plant. Those fungicides that remain on the surface and act upon direct contact with the fungus are called contact, or local. But the effect of such fungicides depends on the amount of the drug, on chemical resistance, and also on the weather, because the drug is easily washed off from the surface of plants by rain.

Another group of fungicides are systemic (or intraplant), they spread inside the plant, destroying pathogenic fungi from the inside. These fungicides no longer depend on the weather; their effectiveness is determined only by how quickly the drug penetrates the plant.

Mode of application

Fungicides can be applied in three different ways.

The first is seed treatment before planting. This is done either using dry powder or a solution of fungicide in water.

The second method is spraying adult plants. In this case, treatment is carried out with a fungicide solution, usually this is done in spring and autumn (as a preventative measure), and also when the plant is infected with a fungus and needs to be cured.

You can also apply the dry preparation or its solution directly to the soil before planting the plant. This treatment will destroy any fungi that may be in the soil and prevent infection of the plants.

All fungicides must be used strictly according to the instructions so as not to harm the plant. You also need to remember that many fungicides are classified as substances of medium danger. But there is no need to worry, if you handle fungicides correctly, they can only harm fungi.

That is why it is very important to follow safety precautions when working with fungicides: protect your hands with gloves, wear protective clothing, and wash your hands thoroughly after work. Also be sure to isolate children and pets from the premises.
