In the arsenal of each experienced one there are preparations in the form of an emulsion, powder or suspension. In the fight against fungal diseases of plants, they are simply irreplaceable. Similar agrochemistry can be found on sale different types impact. Let's consider the most popular fungicides for and analyze each name in terms of the sensitivity of pathogenic fungi to it.

Did you know? For the first time about chemical method processing plants began to speak in 470 BC by Democritus. In his writing, he reflected on the need to spray flowers from powdery mildew water infusion from olives. A ancient philosopher Homer advised the use of sulfur in the fight against pathogenic microbes and pests.

"Trichodermin"

The drug is organic fungicide based on grain substrate and active soil bacteria Trichoderma lignorum, the vital activity of which contributes to the suppression of fungal spores.

"Trichodermin" is able to cope with 70 types of pathogens of fungal plant diseases. In particular, such as: seed infections, fusarium, macrosporiosis, root rot, late blight, rhizoctoniasis.

The agent begins to act upon contact with microorganisms, without poisoning the culture. It is distinguished by the ability to improve soil fertility, stimulate root nutrition and increase the germination of seeds.

Outwardly, it is a light powder, which is sold in bags with a capacity of 10 g. For disinfection with root lesions, the contents of the package are diluted in 1 liter of water and moistened with a suspension in a pot. And for the treatment of the aboveground part of the flowerpots, the entire drug from the package is dissolved in 5 liters of water. Also "Trichodermin" is recommended for prophylaxis during transplantation (a pinch is added to the substrate), when rooting cuttings of Saintpaulias (they are poured a little into the water).

The rest of the unused solution is best placed in a closed container in the cellar and stored for no more than 4 weeks. And when using it again, wait until the product reaches room temperature.

It is a biological fungicide for plants in the garden and in the house, containing a bacteria called Bacillus subtilis.
They act on pathogens of fusarium, powdery mildew, gray and white rot, late blight, leaf spot, keela, mildew (downy mildew).

"Gamair" is released in the form of tablets. For watering flowering and decorative crops, 1 tablet must be dissolved in 5 liters of water, and for spraying, 2 tablets and 1 liter of water are needed. To achieve the desired result, repeat disinfection for a week. three times a day.

Bordeaux liquid

This fungicide made it to the list of the most strong drugs from pathogenic microbes and fungi. It can be purchased ready-made, or you can cook it yourself.

To do this, in separate non-metallic containers, pour 300 g of quicklime and boiling water (not steep). Then, in each bowl, bring the composition to the required volume (up to 5 liters) using cold water.

After filtering the lime solution through a gauze folded in several layers, slowly add the contents of the second dish to it. The result should be a bright blue 3% mixture with active copper and acid-neutralizing lime.

Be careful: Failure to comply with the proportions will harm the plants. For example, if you do not add lime powder, the flowers will get severe burns after being treated with this remedy. The given ratio of components is intended for volumetric foci of infection. At the initial stages of the disease, it is recommended to cook for flowerpots in a ratio of 100 g: 100 g: 10 L.

If after processing the solution remains, it can be stored for 24 hours by adding a teaspoon of sugar (10 liters).

Important! You can determine the acidity of the Bordeaux liquid using an iron nail. If, when dipped into a solution, it becomes covered with a reddish copper bloom for 5 minutes, the reaction is acidic.

The fungicide is intended for spraying the aerial parts of plants and acts on pathogens for 2 weeks, does not suppress the reproduction of mealy fungal spores.

The suspension is recommended for processing plants during the flowering period, as it increases the percentage of the formed ovary and the development of roots.

It interacts well with organochlorine and organophosphate substances, but it cannot be mixed with Bordeaux liquid.

Released in pill form. For processing underground parts plants are diluted with 2 tablets in a bucket of water, and for spraying the stems and branches - 1 liter of water and 2 tablets of "Alirin" are enough. In case of severe infections, it is recommended to repeat the disinfection after a week. Maximum number of treatments - 3 .

Did you know? In the struggle for the harvest, people experimented with different chemical compounds, treating plants with them. The Frenchman Milarde once noticed that after spraying with copper sulfate with lime, the vineyard is not affected by mildew. This is how the discovery happened Bordeaux mixture.

"Agate"

It is a biological product of antifungal and antibacterial action. After its use, there is an increase in yield by vegetable crops ah, increased seed germination and the development of a powerful rhizome.

For these qualities, the fungicide was loved, but it is successfully used as a prophylactic agent and flower growers.

Microorganisms act as the active substance of "Agatha" Pseudomonas aureofaciens... The drug is marketed in 10 gram vials with a flowable paste. The working solution is prepared at the rate of 3 liters of water per 1 scoop of fungicide. The processing of flowerpots with the resulting composition is carried out three times with a 20-day interval.

The product is intended for prophylactic treatment of indoor flowers against lesions and pathogenic microbes. It is used as one of the components of disinfection mixtures.

The fungicide has a depressing effect on other sucking insects, as well as on pathogens of scab, rust, powdery mildew and late blight. For prevention, spraying is carried out 4% solution of "Green Soap".

The drug is dispensed in plastic bottles different capacities. A slight sediment is allowed at the bottom of the container.

Maximum number of treatments - 3 ... If we are talking about the disinfection of citrus crops, then the processing is planned a week before harvesting the fruits.
The solution is prepared depending on the attacking pathogen or pest. For example, a mixture of tobacco tincture and "Green soap" is used for sucking insects in a ratio of 2 l: 25 g, and in case of infections with harmful microorganisms, 2 g are dissolved copper sulfate in 1 liter of water and add a fungicide to the solution.

Important! Before starting work with fungicides, be sure to take care of safety, protecting yourself with overalls, rubber shoes, gloves, goggles, headwear, and, if necessary, a respirator.

This fungicide from the list of pesticides for ornamental, technical, medicinal, fruit, vegetable, flower, and forest plants.

The active substance of the drug ( copper oxychloride) acts on pathogenic fungi and microbes upon contact with them.

Produced in the form of an aqueous suspension, poured into bottles of 50 g and cans of 12.5 liters. Experts note high dispersion active components of the product, which contributes to uniform distribution on the stems and leaves of indoor flowers.

In addition, "" is effective as a prophylactic agent, has an effect regardless of temperature conditions... The working solution is prepared by diluting the drug according to the proportions indicated in the instructions. The rest of the suspension can be saved for a long period.

"Fitosporin"

On sale there is "Fitosporin-M". It is an organic fungicide used to fight diseases caused by fungal spores and bacteria.

It is released as a powder, liquid or dark brown paste. Among the significant advantages of the substance, it is noted that it is economical, has a long shelf life and a wide spectrum of action. Processing can be carried out by foliar and root methods. In addition, it is recommended to use "Fitosporin" for soaking seed, rhizomes of seedlings when planting, protecting flower tubers and bulbs when laying in a cellar for the winter.

Did you know? The history includes the facts of the use of the drug in 1778 as an insecticide from crude oil and kerosene to combat the scabbard on orange trees.

This biological product is simultaneously an antidote, fungicide and growth stimulant.

Agronomists recommend it for plant recovery after herbicidal stress, prolonged droughts, hail, during various fungal infections, with poor germination of grains and low yields.
The drug has no toxic effect on flowerpots and people. For the purpose of preventive and therapeutic measures, it is used for root rot, bacteriosis, leaf spot. The active ingredient "Albit" is not addictive to pathogens. Very effective for indoor plants.

For processing ,

Growing horticultural, orchard or ornamental plants- a favorite pastime of many gardeners and summer residents. However, you need to understand that growing a healthy culture without proper care impossible. It is important to provide each flower in advance reliable protection from all kinds of diseases and dangerous pests.

Biological action of fungicides

When caring for the garden, summer residents often have to use high effective drugs - plant fungicides, which are potent chemicals that can provide effective fight with pathogenic microorganisms that cause the development of fungal diseases, such as:

• powdery mildew;
• gray rot;
• root rot and others.

Fungicidal agents are divided into two groups according to the method of exposure:

• contact;
• systemic.

Every gardener should know what fungicides are, how to use drugs in home gardening.

The use of fungicides for plants excludes the possibility of penetration of active substances inside. They manage to cover only the outer part of the culture, where the generative and vegetative organs of the fungus are located, causing further progression of the infection.

All funds are capable of acting for a different period, which depends on the duration of the stay of chemical compounds on the surface of the culture. A special result is seen with regular treatment every 3-5 days with an interval of 10-12 days.

The key feature of contact fungicides is local action on green spaces. They are used not to treat signs of damage, but to destroy pathogenic fungal formations that are located on the surface or in plant tissues. It is important to understand that fungicides are not able to penetrate other parts of the plant, therefore, processing with their help is completely safe.

Action systemic drugs is built on a different principle: during processing, they affect everything internal systems, moving through tissues and introducing a number of changes in the physiological and biochemical processes that take place inside plants.

Subsequently, they decompose in the internal organs of flowers, garden or agricultural crops, which causes the rapid formation of metabolites. In this state, the plant develops strong immunity, which contributes to the rapid cleaning of harmful fungi.

Some gardeners are of the opinion that it is unsafe to use systemic fungicides, since decomposition products formed after processing can harm the plant. To prevent possible complications, it is necessary to use chemicals of the first type - contact... However, it is important to have time to carry out all processing procedures one month before harvest.

Types and principle of action

When looking for fungicides in specialized stores you can find ready-made solutions powder, suspension or emulsion with good water solubility. Depending on the composition, there are several fungicidal preparations:

• Inorganic. Among them are drugs of 1-4 classes of danger for humans and warm-blooded creatures.
• Organic. The composition of such funds contains active microorganisms that can have a depressing effect on pathogenic fungi.

For use in summer cottages, it is recommended to use biological fungicides, since they are distinguished by excellent efficiency and, at the same time, are practically harmless, both for garden crops and for the human body. However, when carrying out processing activities, all safety rules must be observed.

Chemical fungicides

Many modern summer residents and gardeners are looking for the most effective drugs to combat diseases of fungal origin. Looking for good decisions they pay attention to innovative chemicals that guarantee high performance in low doses.

However, it is highly discouraged to get carried away with such means, and the effectiveness declared in advertising is not always a reality. The list is really good fungicides chemical type, which have managed to prove their effectiveness after lengthy experiments and research, it is important to highlight:

• Bordeaux liquid;
• copper sulfate;
• abiga-peak, sun;
• zineb;
• potassium permanganate;
• soda ash;

Such products have been tested by experts and have earned the right to be called one of the most effective of its kind. However, when using chemicals on site, you need to be extremely careful and carefully study the instructions for use. V otherwise you can harm yourself and the crops you grow.

Biological preparations

The range of highly effective fungicides is very extensive. Moreover, in last years new solutions are entering the market that can protect plants from all kinds of diseases. Among them contact biological fungicides... They are made according to a completely different principle than the previous chemical ones. Such preparations are based on active bacteria that localize the causative agents of fungal diseases and have a detrimental effect on them.

Biofungicides allow you to effectively fight the problem without harming green spaces, animals, fish, bees, as well as people. If you want to buy good biologicals, take a look at the following list:

• Gamair P;
• Trichodermin;
• Alirin-B;
• Albite;
• Fitosporin;
• Agate;
• Planzir and others.

It is important to understand that it is necessary to start treating plants with contact chemicals long before flowering, as well as after harvesting. As for biological solutions, they efficiently work throughout the growing season. In addition, among biofungicides, there are also such preparations that can be used at the stage of fruit ripening. In any case, the novice gardener should understand that all fungicides are just preventive tools. If the active substances reach the causative agents of the problem, this causes their death. However, if the disease progresses, and the culture is severely affected, then such drugs will not be able to solve the trouble.

How to work with contact fungicides

As mentioned above, the use of fungicides is quite demanding and painstaking process... Before starting work, you need to carefully consider safety issues by preparing specialized clothing, rubber gloves, glasses and a hat. After carrying out processing work, clothes should be thoroughly washed, and hands and face should be washed with soap.

Before you start processing garden, horticultural or agricultural crops, prepare a ready-made solution, observing the correct dosage and all the recommendations that come with the instructions. Also, do not overlook the advice of experienced specialists, guided by their personal experiences and skills.

Particular effectiveness from the use of fungicides is noticed when processing in the early morning or evening, in dry, calm weather. If spraying was carried out before or after rain, good result there is no need to wait. The active substances will simply be washed off by the rain and will not take effect. As a result, the defeat will progress.

When spraying, you need to select the mode of operation for fine spraying. The resulting cloud of solution should spread to the bottom and top of the plant.

It is important to understand that you cannot spray the green parts of crops that will be eaten. To increase safety, it is necessary to have time to process green spaces before flowering and fruit setting.

Use the container where the solution was for repeated work Absolutely forbidden... Instead, it must be disposed of in designated pesticide areas. Storage areas for fungicides should be limited from public access, while preparations should be kept in sealed containers.

List of drugs

Most of the available fungicidal preparations have high toxicity... Therefore, before you buy them and use them on your site, you need to find good reasons. It is also necessary to carefully read the instructions for use and make sure that you can carry out the processing activities yourself. Let's highlight the list of the most popular and effective fungicides for plants.

Oxyhom

The composition of this drug from the contact-system group contains copper oxychloride and oxadixil. Most often it is used for preventive purposes and the suppression of all kinds of diseases of garden and indoor crops... Fights well with late blight, macrosporiosis, black bacterial spot and other dangers. The absence of toxicity increases the safety of using the product.

To start processing, you must first prepare a highly effective solution. First, pour 1/3 of the water into the tank of the device, and then start the stirring mechanism and add a little of the drug. In the future, it remains to pour in the rest and stir the solution well. The ready-made mixture is used for abundant spraying of crops that have succumbed to the fungus. In the process, it is important to use exclusively clean water.

As for the dosage, then optimal performance keep at around 1 Oxychom package for two liters of liquid. Sometimes it is necessary to carry out up to three procedures with an interval of 10-14 days. Only freshly prepared solution is used for processing.

Among significant advantages funds:

• highly effective systemic contact action;
• the ability of long-term preservation of the effect;
• minimal toxicity if the treatment is carried out at the correct dosage;
• economical consumption for preventive purposes.

Trichodermin

This biological fungicide is different high efficiency in the fight against pathogens of fungal and bacterial diseases. The biofungicide contains spores of the soil fungus Trichoderma lignorum and crushed grain substrate.

The drug is capable of eliminating more than 60 varieties of pathogenic organisms that cause all kinds of diseases, including:

• root rot;
• seminal infections;
• fusarium and other troubles.

The action of active substances causes improvement of soil fertility indicators, rapid saturation of the root system with additional nutrients, as well as an increase in the germination of planting material.

To prepare a suspension where the seeds will be soaked, it is enough to take 10 grams of the drug and dilute it in one liter of water. If the agent is applied by watering plants, then the optimal dosage will be the same as in the previous case. When watering, it is important to deliver the slurry directly to the root using medium portions of water.

A ready-made solution for spraying is created as follows: 10 grams of the agent is supplied to 5 liters of water.

Trichodermin has excellent preventive action during transfer operations... In this case, the consumption rate is determined as follows: for a 25-centimeter (in diameter) pot, the amount of the drug is used, which is placed on the tip of the knife.

By the way, not only adult plants can be treated with this tool, but also young cuttings by placing it in water, where they are kept before planting. In this case, the consumption is 5 grams per 5 liters.

To effectively fight all kinds of diseases, it is necessary to prepare such a suspension: dilute 5 grams of the substance with 5 liters of water. Then the damaged culture must be removed from the pot and cleaned of the soil composition.

The affected root elements will have to be removed, and the main rhizome should be thoroughly rinsed with a suspension. After that, it is better to transplant the plant into another pot, where fresh substrate was previously placed.

The problem of protecting garden, ornamental and agricultural crops is of interest to many gardeners and summer residents. To effectively fight all kinds of diseases, highly effective chemicals are often used, including fungicides. With their help you can quickly and efficiently get rid of the problem and prevent its further progression.

However, in order for the drug to be very effective, but at the same time safe, when choosing suitable solution it is necessary to give preference to those agents that have the least toxicity. By choosing best drug, take into account the advice of professionals, and read all attached instructions and recommendations. Such simple actions will prevent unwanted consequences from improper processing.

In the process of caring for plantings, fungicides have to be used for plants. We are talking about the drugs that are used for the prevention and control of pathogens - the cause of the spread of fungal diseases. Their pathogens are capable of infecting both one culture and a group of plants. In order not to cure 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, paying attention to the immunization of crops.

And until the time invisible microscopic size - equally an enemy.

Invisible enemies cause diseases that can be called infectious because they are transmitted from one plant to another. Means that can fight plant diseases are called. In fact, these are killers of fungi that infect plants.

Classification of fungicides

You can define classes in different ways. For example, you can divide by preventive, when processing is carried out, adult plants during physiological dormancy, in, and on preparations that protect plantings during the growing season, so to speak, by detection illness.

Another option is by pathogens diseases. It is also possible by the way the substance works: on the surface of the leaves, without penetrating into the tissues of the plant ( contact), or vice versa, penetrates the plant and there destroys the enemy ( systemic). Division by contact and systemic is the division of fungicides by mode of action on the causative agent of the disease.

And it is very difficult for a layman to divide by impact on life mushrooms. Some substances disrupt respiration, others do not allow multiplication, others do not allow nucleic acids to form, and there are still fourths ...

Toxicity of fungicides

It is generally accepted that the amount of fungicide that has penetrated into the plant is not dangerous to humans and domestic animals under the following conditions:

• if all technological methods and terms of plant processing are observed;
• the terms of harvesting after processing were met.

Crop protection specialists, of course, know which active ingredients are used and in what quantities. And the summer resident does not know for sure.

Active ingredients of fungicides

There are twins in this industry - drugs with different names, but the same active principle.

Azoxystrobin

There are no other names. Fungicide of contact and systemic action. Azoxystrobin is effective in tomato disease, alternaria, in cucumbers with and, in grapes with damage and, with onion oversporosis (if it is grown to obtain feathers, then it cannot be processed), with.

Clean azoxystrobin contained in the preparation " Quadris". All other products are mixtures with other substances. For example, " Maxim Kvatro"(Four active ingredients, protection of seeds and seedlings from infections stored in soil and seeds) and" Uniform"(2 active ingredients, protection of potatoes from rot).

Benomil

Known since 1968. I am familiar to many by the preparations with which they pickle seeds and water the soil under the plants: “ Arylate», « Benlath», « Fungicide 1991" and " Fundazol». « Benomil 500»- preparations that contain only this active ingredient (each kilogram of the preparation contains 500 g of the active ingredient).

Effective in the treatment of tubers and flower crops before planting or storage.

Dimethomorph

Other names " CME 151», « WL 127294», « Acrobat". Dimethomorph is classified as a systemic fungicide that can fight the causative agents of late blight and Alternaria on potatoes, mildew on grapes, and peronosporosis on cucumber plants. All pathogens belong to oomycetes, which biologists classify as either fungi or bacteria. For summer residents and gardeners, something else is important: they are the cause of the black leg on cabbage, downy mildew on table beets.

Mixed preparations containing dimethomorph. It " Acrobat MC», « Mancodym», « Rapid Duet" and " Gymnast"(Mancozeb and dimethomorph) for the destruction of late blight and alternariosis of potatoes, peronosporosis of cucumbers, mildew of grapes, and also" Acrobat Top"(Dimethomorph and dithianon) to combat grape mildew.

Dithianon

Contact fungicide. Other names " Delan», « MV 119 A», « Delancol», « Tinon". Preparations containing only diatinone: " Delors», « Delan", Both with the same concentration of active ingredient. They help in the fight against fungal diseases of fruit and grapes. It is believed that it does not penetrate the skin of the fruit.

There are mixed preparations: " Acrobat Top"(See information above) and" Tersel", In which pyraclostrobin is added to the diatinone. Dithianon remains on the leaves and prevents the pathogen from penetrating into the leaf, and the second substance penetrates the leaf. " Tersel»Effective against diseases of apple trees.

Difenoconazole

Other names: " Geyser», « Speed», « Bogard», « Dividend". For summer residents and private household plots, drugs containing only difenoconazole have been registered: “ Discore», « Planthenol», « Rajok», « Speed», « The keeper», « Pure bloom»With the same concentration of active ingredient. These products protect pears, apple trees (processing in the phases of green cone, rosebud, flowering, fruit growth), as well as potatoes and tomatoes. " Pure bloom»Is positioned by the packing company as protection against powdery mildew, gray mold and various spots.

Kresoxim-methyl

Other names of the substance: " Mentor», « Allegro". For summer residents, the drug " Strobe", It has a wide spectrum of action. However, the substance itself is proposed to be used to combat soot fungus, scab, powdery mildew, leaf spots on apple trees and pears, as well as in cucumbers with powdery mildew and peronosporosis, tomatoes in late blight and powdery mildew.

"Ridomil" (trade name)

Others: " Apron», « Alacid», « Metalaxil», « Mefenoxam". The substance has been known since 1977, it coped well with powdery mildew, but by 1981 strains of pathogens appeared that were already resistant to the new fungicide in the vineyards.

A drug " Rapid Mix"(The composition also includes mancozeb) is effective for protecting grapes from mildew, a similar preparation" Metaxil"(With the same active ingredients in the same concentrations) is positioned to fight diseases in tomatoes, potatoes, cucumbers and onions.

Penconazole

Other names: " Avard», « Topaz". For private household plots and summer residents, the latter is recommended for powdery mildew of cucumbers and.

Cymoxanil

Throughout the growing season, tomatoes are attacked by various fungal diseases. Fungicides will help prevent the development of an illness or cure plants. Manufacturers of the chemical industry released 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 that allow you to quickly eliminate the symptoms of the disease;
• biological origin. The preparations consist of 90% beneficial living microorganisms that destroy harmful fungi. Biological fungicides 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 in preparations there are: manganese, mercury, sulfur, nickel, copper, iron;
• organic - environmentally friendly drugs that quickly decompose in the soil.

Depending on the direction of action:

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