Antifungal drugs for flowers. Fungicides - an overview of the means of controlling the fungus on plants. Other fungicidal preparations

To fight dangerous diseases and pests of plants in the garden, garden, indoor flowers often use fungicides. What are these substances? What is the reason for the high efficiency of the compositions?

What are fungicides

Substances of biological or chemical origin are used to prevent, eliminate and prevent fungal infections, to control pests for indoor flowers, horticultural crops. The preparations are effective for protecting seeds during dressing.

Translated from Latin fungicide means "killing fungi". The timely use of antifungal compounds preserves the health of plants, increases productivity, and prevents the spread of fungal infections.

Properties and features

Proper application of fungicides for plants guarantees the protection of fruit, vegetable crops, indoor plants from pathogenic fungi. Consultants of the Home - Garden - Garden stores or specialized departments of building supermarkets will tell summer residents and amateur flower growers which tool will help in a particular case.

Fungicides differ in several parameters, have different strengths. When buying compounds, you need to consider many characteristics.

Origin:

• organic (antifungal action is based on the activity of certain bacteria);
• inorganic (preparations are made on the basis of various chemical compounds).

Degree of decomposition:

• long remain in the soil (inorganic substances);
• harmless to environment, completely biodegradable (components of natural origin).

Impact force:

• herbal formulations are “softer”, the effect is weaker, but there are few side effects;
• chemicals act faster, more actively, but are often toxic, the use requires caution.

The nature of the distribution in plant tissues:

• contact. They act on the surface of leaves, stems, have a detrimental effect on fungi upon contact with the active substance;
• systemic. Substances through the vascular system of plants penetrate into the tissues of fruit and vegetable crops, some drugs act even in the seed coat.

According to the purpose of application:

• soil treatment;
• dressing of prepared seeds;
• spraying plants during the growing season;
• prevention of fungal infections when laying grain and vegetable crops for storage;
• fight against the fungus during the dormant period;
• universal compounds.

On a note! Biologics have become more popular last years. Summer residents and flower growers decided that it was not worth risking the health of plants: chemicals are more active, but worsen the condition of the soil. Toxic compounds often provoke poisoning of people if protective measures are not followed when using potent fungicides.

How to apply

Treatment is carried out with fungicides in the form of a powder (introduction into the soil, dressing seeds) and a solution (spraying plants). Certain types of preparations are recommended at different periods of the life of fruit and vegetable crops.

When fighting fungal infections of vegetable and fruit crops, indoor flowers, it is important to remember the protective measures:

• put on old clothes covering the entire body;
• put on a medical mask or respirator;
• protect your eyes with special transparent glasses;
• after treatment with any form of antifungal agents, wash your hands well with antibacterial soap;
• clothes can not be used for everyday wear: dry the washed things, iron them, put them in a separate box.

For indoor flowers

Application:

• for the prevention and treatment of fungal diseases, treatment is carried out with contact and systemic fungicides;
• at home, experts advise paying attention to biological products containing active bacteria;
• compositions in the form of an emulsion, powder, spray solution are suitable for use in city apartments;
• chemical fungicides are allowed to be applied before the start of the growing season after the end of the flowering and fruiting period. Biological preparations can be used at any time (some formulations are suitable for treating fruits at harvest).

For garden plants

Application:

• solution and powder are suitable for dressing seeds. The agent is added to the water during the soaking of the seeds;
• introduction into the soil during digging. Fungicide powder and antifungal solution (watering) will prevent the development of the fungus in the soil;
• spraying in early spring and towards the end of autumn. This method is suitable for antifungal treatment vegetables and granaries.

How to breed

Prepare a solution or reduce the concentration of the emulsion according to the instructions for the selected fungicide. For each tool there are certain proportions.

General rules:

• prepare a container: a tank, a bucket;
• pour a third of the water;
• pour powder or add concentrated emulsion;
• to stir thoroughly;
• add the remaining water, mix well again;
• to fight the fungus, use only a freshly prepared solution: after a few hours, the drugs reduce their activity, especially biological agents.

Advice! Do not prepare a fungicidal agent in reserve. It is forbidden to leave the solution open for storage: this moment is critical if there are small children. Pets can also be poisoned if they drink part of the composition.

Safety precautions when working with fungicides

During the treatment with fungicides, you can not use food utensils, smoke, drink and eat. The treatment is carried out in the absence of children, animals, and if there is an aquarium nearby, then it is tightly closed and opened only when the treated plants are dry. At mass defeat diseases, you can treat all contact surfaces (window glass, frames, window sills, tiles, etc.) if possible.

For those who suffer from allergies or skin eczema, the treatment is best done with gloves and a gauze bandage. Do not forget to look at the hazard class of the drug used. After finishing work, hands, face and all equipment used should also be washed with soap and water. Store fungicides in a dry place, out of the reach of children and animals, keep away from fire.

In case of accidental ingestion of the fungicide into the human body, drink several glasses of water, induce vomiting and immediately consult a doctor.

Every growing season, gardeners and growers fight for the harvest. Complicating their task is the fact that plants suffer from various diseases and pests. People use against themfungicides for plants, drug listThis group is extensive and constantly updated. How to understand such a variety of chemicals? Are they really universal and help solve all problems?

Classification

Consider the most popularfungicides - drug listand their characteristics, but first you need to know their classification. This will facilitate the selection and subsequent purchase of a suitable product.

Depending on the chemical properties

According to their chemical nature, fungicides are divided into:

• to inorganic;
• organic.

The group of inorganic preparations includes:

• copper-containing - Bordeaux liquid, Burgundy liquid, oxychloride and copper oxide;
• sulfur-containing preparations - colloidal sulfur, lime-sulfur decoction;
• mercury compounds.

Organic fungicides for plants refer to different chemical compounds. The leading role is occupied by heterocyclic compounds, these are various nitrogen-containing derivatives. Many organic preparations are effective against pathogenic microorganisms.

Depending on the effect on the pathogen

On this basis, drugs are divided:

• on protective (preventive);
• medical.

Protective fungicides prevent infection of crops with phytopathogens that have Negative influence on the root system and metabolism.

Phytopathogens are various pathogens. They secrete biologically active substances, which, in turn, adversely affect the development of plants.

Curing fungicides are drugs that strike at phytopathogens that have already invaded plant tissues. Curing contact fungicides cannot penetrate into the tissue and have a local effect. They are divided into preparations of selective and continuous action. The former suppress the reproductive and vegetative organs of the fungus, and the means of continuous action also suppress its resting forms. Therapeutic systemic preparations penetrate into plants, spread through the vessels, stop new foci of infection and destroy phytopathogens.

According to the purpose of application

Fungicides according to the purpose of application are divided into the following varieties: For soil treatment - soil. They are introduced immediately into the soil for its disinfection, this is especially true for soil in a greenhouse and hotbeds. Fumigants are usually used - these are preparations in the form of gases or vapors.

For dressing seed material - use drugs that fight diseases and infections spread by seeds or in the ground. For the treatment of plants during the growing season, these are mainly protective fungicides that prevent diseases. For processing plants at rest. They have a contact eradicating effect, destroy wintering pathogens and pests. Since the substances severely damage the green parts of plants, they are used in early spring before the buds awaken, in autumn and winter.

Depending on the nature of distribution within plant tissues

According to the distribution of the substance in the tissues, fungicides are:

• contact;
• systemic.

After treatment with contact preparations, they remain on the surface of plant parts. In contact with the pathogen, the active substance causes its death. The effectiveness of drugs depends on weather conditions, duration of action, concentration. Systemic drugs penetrate into plants and spread through the vascular system, suppressing the pathogen during metabolism or acting directly on it. Efficiency depends on the rate of penetration of the active substance into the crop, as well as on the weather (it affects to a lesser extent).

Most systemic fungicides have both preventive and curative properties.

Kinds

Fungicides by their nature are:

• chemical;
• biological ( biogenic origin).

Chemical fungicides have an unstable effect, after the termination of their action, the treated area is again populated by pathogenic microorganisms. It would seem that treating plants and soil on a regular basis will help solve the problem, but everything chemical substances toxic, so use them permanently prohibited. Part biological preparations includes various strains of microorganisms that destroy harmful microflora. They have a persistent long-term effect, are non-toxic, but are effective only at the onset of the disease or as a preventive measure.

There are too many factors involved in choosing the right fungicide for any given application. The type and age of the plant, the type of disease and its "neglect". Even the weather, the area of ​​green spaces and the presence of pets in the vicinity play a role. It's easy to get confused.

We do not recommend buying a fungicide at random: the advertised chemical may turn out to be a “dummy”. It is possible that he is even capable of harming a diseased plant. The best thing is to trust the opinions of professionals.

In our manual, we have collected the recommendations of scientists and the advice of experienced farmers. We deliberately put a review of the most effective fungicides at the very end of the material, because in order to cure a plant, you first need to make a correct diagnosis. And in order to make a correct diagnosis, you need to know everything about plant pests. This is what is dedicated most of our guide.

You need to defeat the fungus wisely!

Why is the fungus dangerous for plants?

All fungicides have a common enemy - pathogenic fungi, which so easily infect ornamental and agricultural plants. Farmers and housewives, food producers and gardeners suffer from them.

Here's what fungal spores and fungi themselves are capable of:

• - They disfigure plants: various diseases are reflected in the color and shape of fruits, leaves and flowers;
• - Mushrooms deprive us of the harvest. In just a couple of weeks, they can cause damage to plantings of potatoes, apples, grapes and wheat, tomatoes and cucumbers, blueberries and strawberries;
• - They kill them. your favorite lawn or home flower may die if they are not treated in time with the necessary fungicide;
• - fungal diseases hitting the pockets of farmers and the state. In some cases, the degree of crop loss from the fungus becomes catastrophic, up to ruin.

It is very difficult to avoid infection with a fungus without preventive measures. Spores live in soil, air, on other plants and in water. They are carried by the wind, animals and even people! And then mycelium comes into play: thin threads, something like a mycelium. They penetrate the tissues of the plant and begin to devour living matter. In addition, fungus-covered leaves do not receive light and die without the possibility of photosynthesis.

The most common fungal plant diseases

The presence of a fungus in a plant is most often indicated by external symptoms. White bloom and rusty pads, colored spots and sores, fragments of rot and bumpy growths may appear on the greens. In addition, plants wither, deform, dry out, become thinner, become overgrown with tumors and cease to bear fruit from fungi. In the case of lawn and grass, bald spots form on the ground. Any of these symptoms cause dozens different types fungi. This system is not easy to streamline, but still the most common diseases have received their folk and scientific names. Here are some of them.

Powdery mildew. This is a universal villain that affects the leaves, fruits, stems and flowers of plants. white bloom(mycelium) in a couple of days can completely tighten garden rose or grapevine. The disease kills the fruits the longest: they rot and crack. Especially loves "powdery mildew" young shoots. Pumpkins, peaches, gooseberries, cereals, roses, even sugar beets... who doesn't suffer from it!

Snow mold. This is the enemy of all lovers of natural lawns and tall grass. "Snow mold" usually appears in early spring, after the snow melts. It spreads in circles 3-12 inches in diameter. When these circles "breed", the lawn can completely die. First, pink, white or gray mold will cover the lawn ... then the mushrooms will draw all the juices out of the grass, and it will die. Most often, meadow and reed fescue, perennial ryegrass and meadow bluegrass suffer from this fungus.

Root rot. These diseases like rhizoctoniosis and "black rot" are dangerous for most plants. Fungi undermine the roots of room and garden greenery. You will not know about this for a long time: you will simply follow the smooth withering of the plant. An insidious disease will turn the root system into black dust or rusty dry lashes.

"Spotted" fungus on the leaves. A disease affecting vegetables. Leaves develop fatty dark spots. Most often, tomatoes and peppers, potatoes, asparagus, rhubarb suffer from them. This "beauty" directly affects the yield of vegetables. Although the fruits themselves rarely suffer.

And there are also various fungi that affect the grass. It may become covered with rust-colored blisters and red-brown rings (Fusarium disease). The lawn may turn brown and disappear under small cotton clouds (Pythium's disease).

Prevention of fungal diseases

Fungi love high humidity, stagnant weather and proximity to other plants. Therefore, it is necessary to observe a certain interval between plantings, as well as save them from excessive watering and poor air circulation. These rules are especially relevant for greenhouse plants. You need to regularly monitor the cleanliness of the soil and dispose of dying plantations.

American scientists who have studied this issue are asking everyone to be careful with mulching and pruning plants (mistakes during these operations can lead to infection). They also call the best way prevention... the purchase of specially bred varieties resistant to fungus. Sterile pots will protect the roots from fungi, control over the purchased soil mixture is a competent irrigation system that excludes stagnant water.

The classification of fungicides divides them according to the purpose of application. It looks like this.

1. protective fungicides. Organic and inorganic agents for the prevention of fungal diseases.
2. Therapeutic fungicides. Drugs that can stop the development of the disease and even destroy it.
3. Systemic or complex fungicides. They work both for the prevention and for the treatment of plants.
4. Immunization agents. They improve the metabolism of the plant and teach it to fight not only fungi, but also bacterial diseases.

The principle of action of chemicals also differs. There are, for example, contact fungicides. Most often, these are protective agents that "defend" only that part of the plant on which they are located from fungi. The farmers and experienced gardeners popular "treaters". They process seeds and bulbs so that in adulthood they are not disturbed by pests.

IN Lately organic liquid products that move freely through the vascular system of the plant have become fashionable. They can save individual shoots of an already infected plant from diseases, work as a protective and therapeutic agent.

Which is better: organic or inorganic fungicides?

First, it is important to decide whether you are looking for an organic or inorganic fungicide. The former are considered more environmentally friendly and safer for nature and humans. But we are more interested in the practical side of the matter. Moreover, many "organic products" are also synthesized using chemicals.

The advantage of organic fungicides over inorganic ones is that they do not contain rare and dangerous metals. These metals pose a danger to animals, earthworms and, in rare cases, soil. If too much copper or mercury accumulates. But "natural remedies" decompose underground by themselves, this happens very quickly. True, this property also affects the duration of the healing effect (synthetic chemicals last longer).

Organics are easier to “cook”: most often you just need to mix a powder or liquid agent in water. We add that organics can be combined with a large number pesticides than inorganic preparations.

The advantage of inorganic means is consumer confidence. It was the products based on copper, sulfur, mercury and chlorine that were the first to appear on the market: our grandfathers used them. And this is already a certain habit and tradition. Although, logically, younger synthetic organics should be more perfect. But even here it is not so simple. In some diseases, old preparations of copper oxychloride with a concentration of 0.5-0.75% are still not inferior in effectiveness to fashionable synthetic drugs.

Are chemical fungicides so terrible? The USA environment agency writes: “Some of the worst pesticide poisonings come from the misuse of organic mercury or hexachlorobenzene to treat seed. However, most fungicides in use and registered for use in the US are not capable of causing frequent or severe poisoning."

So you can harm yourself and the environment only if you use products that are not according to the instructions! The portal asks to be especially careful with these substances: triazoles, mercury, thiocarbamates, dithiocarbamates, mercury.

Best store bought fungicides

Experts have approved dozens of different fungicides, and it's easy to get lost in this long list of names. Therefore, we decided to help you and selected the most effective tools that can be purchased on the Internet.

Fungicide BORDEAUX LIQUID

A classic fungicide based on copper. Suitable for flowers, fruits and vegetables. It copes well with powdery mildew, black spots and "early" fungi. It must be mixed with water in the proportions indicated on the package and used as a spray. Buyers write that one spray per month is usually enough. But with frequent rains and irregular watering, the product is used more often.

There are several references to the effective use of lawn fungus. In total, about 85% of buyers call the product useful.

Fungicide CLEAR COLOR

A similar product from the same manufacturer. Only here you do not need to dilute anything: the product is sold as a ready-made spray. The fungicide contains copper octanoate, which is a copper salt compound with a fatty acid. At the same time, the concentration level of the chemical protects the greens from burns.

The developer insists on abundant spraying of the leaves. You can even pay attention to their lower part. People in the comments advise not to spray the product on the eve of rain: it takes from 24 to 48 hours for it to be completely absorbed. The next time spraying will need to be done in 2-4 weeks.

We find several dissatisfied comments. To some farmers, the solution seems "weak". But these are special cases - about 80% of farmers were satisfied with the performance of the chemical.

Fungicide Topaz

A well-known universal fungicide that has earned high praise from users. It is suitable for most garden plants and lawns. Especially praised by his fans spray roses. It is a protective fungicide. It is optimally suited for the prevention and protection of plants from fungi. The chemical is not afraid of rain and stays on the leaves for two weeks.

But we still wouldn't risk it.

One bottle is enough for 10 liters of water. The resulting mixture can be applied to both leaves and fruits. In the reviews of the product, we found conflicting opinions about the need for reapplication. Some people wrote that they solved the problem of the fungus the first time. Others - about the mandatory repetition of the procedure in 1-2 weeks. Perhaps it all depends on the type of fungus and the degree of infection of the plant. Fortunately, the fungicide is not harmful to worms and beneficial insects.

Comparative table of fungicides

Daconil® Fungicide Concentrate 16 oz.

Proven by experts means based on chlorotolanil. Great for powdery mildew control. All ingredients are listed on the packaging, they can always be found on the Internet. One bottle is enough for 240 liters of liquid to be used as a spray. The tool is considered a protective fungicide of contact action of the widest spectrum.

Scotts Lawn Fungus Control, 5,000-sq ft, 6.75 Pounds

A tool designed to prevent only lawn diseases. The active ingredient is 2.3% methyl thiophanate. Experienced users recommend using the substance in the spring: otherwise you may be late. After all, kill the fungus Scotts Lawn no longer capable.

One bag is enough for 300-400 m2. Note that the opinions of users about this product have diverged. Some have called it too toxic to use on adjoining territory.

1. First of all, determine the exact disease. Try to give your plant an accurate diagnosis based on external signs of the disease, communication with "brothers in misfortune" and professional advice. Try to buy a remedy for this type of fungus, and not universal options.
2. Pay attention to the environment. Place of growth of a diseased plant, season, air temperature at the time of application of the fungicide, the rate of development of the disease. All this affects the choice of medicine. The relevant recommendation for optimal conditions for use is often found on the label.
3. Learn contraindications. On quality medicines, a list of plants that do not tolerate these fungicides is indicated.
4. Choose between liquid and powder form. Powders are more often created to work in the soil, and liquids are more often created to process leaves and flowers. The effect of fluids tends to start earlier, but it also wears off faster.
5. Compare prices. Prices for the same product or for different fungicides with similar ingredients can vary greatly. As in the case of drugs, it is not always necessary to overpay for a brand if there is a cheap analogue. Of course, it is necessary to check the state certification of all goods.

Even organic products can harm plants and humans if used improperly. Here are 9 tips for them correct operation for novice gardeners.

1. Always follow the safety instructions in the instructions. All spraying is best done in special protective clothing. Most often, a fungicide is a threat to the skin and mucous membranes. Even potted plants must be processed on the street or balcony.
2. Follow the time of year. It is believed, for example, that dithiocarbamic acid derivatives have a positive effect on the growth and development of plants, which is why they are usually recommended for use during periods of intensive growth (spring and early summer). And by the end of summer, copper-containing preparations should be used.
3. Do not mix organic fungicides - captan, cineb, cyram, polycarbacin, dichlon with mineral oil preparations, since such a mixture can contribute to the occurrence of plant burns.
4. Follow the frequency. Most often, the plant is re-treated every 15-30 days. But each product has its own rules, they are indicated on the label. This indicator is also affected by the time of year and precipitation.
5. Don't waste your harvest. It is better not to use fungicides at all at the time of fruit ripening, but to solve the problem of the fungus earlier. If the case is too neglected, you need to use low-toxic drugs. And before that, find out how many days before harvesting you can use them for the last time.
6. Spray in the morning. Experts assure that night and early morning will become best time for spraying liquid fungicides.
7. Watch the weather. Sprays, liquids and all contact products should not be used in rain and wind.
8. Be aware of phytotoxicity. Phytotoxicity is the state when a drug begins to harm the plant. Its cause is a violation of the concentration of the substance, too frequent use of chemistry and the incompatibility of the agent and the plant.
9. Don't give them a chance to adjust. The effect of "resistance" is observed quite often. Fungi simply evolve under the action of fungicides and cease to be afraid of them in future generations. In such cases, Australian scientists advise either to combine means, or to eradicate the fungus before it has time to breed. The same Australians recommend seed dressing.

Fungicides to get rid of powdery mildew

Powdery mildew spores are transmitted by air, water and "from the hands of a person." They love wet and cool weather, they just thrive on houseplants. You can invite trouble by too frequent watering of greenery and a high nitrogen content in the soil.

On initial stage(prevention and first week) can be applied folk methods. For example, a solution of potassium bicarbonate and soap, a copper-soap solution, or a decoction of horsetail. There are a lot of such recipes on the Internet. But if the moment is missed, it is better to take on more serious means.

Engage in complex treatment of plants. Start spraying at the first symptoms of illness. Among biological preparations, neem oil, insecticidal soap, garden oil and the same potassium bicarbonate will help you with this. Of the chemical compounds, pay attention to copper, fenarimol, myclobutanil, propiconazole, triadimefon and sulfur.

Fungicides for the treatment of fungus on the lawn

Most lawn diseases, despite the difference in symptoms, are treated in much the same way. In the matter of their prevention and elimination, the quality plays a particularly significant role. drainage system. It should not resemble a marshy swamp or an African desert. Gardeners advise arranging watering early in the morning so that the earth has time to absorb moisture during the day.

Fungi are more likely to appear in lawns that are frequently and heavily trimmed with a lawn mower. Any incision is a risk of fungal attack. It is also known that young grass has weak immunity compared to the old one. Note that fungi do not like heat, which means that it is easier to fight diseases in the summer.

But these are just preventive measures. What treatments do experts recommend? For lawn root rot they recommend the following remedies: Spectracide immunox, Fertilome Systemic, Ortho lawn disease control, Propiconazole. For the most part, these are water-based systemic fungicides.

With colored circles on the grass fit: Turfcide, Spectracide immunox, Hi-Yeld Maneb and Green Light broad spectrum. Here the bet is made on the protective means of broad action. However, some complex fungicides may also be suitable.

Fungicides for the treatment of snow mold

From most fungal diseases, "snow mold" is distinguished by the fact that it attacks plantings in winter. The fungus settles in the lawn with the first cold weather and early snow. You will see manifestations of the disease only in spring and summer, when young grass sprouts on your lawn. The owner of the weed will have time to prevent the "epidemic". First, you will need to remove the remnants of the old greenery late autumn to destroy the springboard for a possible "fungal landing". Secondly, in the spring, re-remove all natural debris and carry out the correct mowing of the young.

There are many on the market preventive fungicides against this bullshit. The experts recommend the following line of products (mostly chemicals in granules to be mixed with water): Terraclor 75WP, Ferti-lome Azalea, Camellia, Crape Myrtle Insecticide and Fungicide, Hi-Yield Turf and Ornamental Fungicide(containing 10% PCNB), Hi-Yield Terraclor Granular Fungicide. (more on them below)

For autumn prevention the DMI fungicides strobilurins and dicarboximides are also suitable. They need to be applied to the soil at the very end of the season.
To protect plantings Ortho Garden Disease Control (Daconil 2787), Hi-Yield Daconil Lawn Vegetable Flower Fungicide, Fertilome Lawn & Garden Fungicide, Fertilome Broad Spectrum Liquid Fungicide and Bonide Fung-onil are already familiar.

Potassium bicarbonate is a traditional homemade fungicide.

Potassium bicarbonate is an organic chemical compound (KHCO3) in powder form white color, which is widely used in various fields: from medicine, sports, cooking and to Agriculture. This protective fungicide is a real lifesaver for plants growing in acidic soils because it:

• has low toxicity;
• protects vegetables (particularly pumpkins) and ornamental plants from powdery mildew;
• reduces the rate of reproduction of harmful fungi and bacteria.

BUT! Potassium bicarbonate does not protect against black spots on roses and against direct plant contact with fungi.

Why is it often used as a replacement for soda (NaHCO3) in plant treatments. Based on the composition of these chemical compounds, it seems that there is almost no difference in them and they are similar in chemical properties. But this is only at first glance.

It is known that when in contact with the soil, both soda and B.K eventually settle in it in the form of chlorine salts - which are useful for the growth and nutrition of plants, but in excess carry great harm(especially sodium from soda). Therefore, you can not use these fungicides randomly! Processing them is possible only in certain seasons - in spring or autumn, depending on the type of soil. You can use any of them, but B.K. considered more effective than soda.

Unlike B.K., soda does not kill powdery mildew on plants, but only prevents its spread, which was repeatedly recorded by those gardeners who used it as a fungicide and compared the action with B.K. Therefore, the choice between potassium bicarbonate and soda seems to us virtually obvious.

We offer you the most popular recipe using potassium bicarbonate:

“Mix 4 teaspoons (or 1 heaping tablespoon) of potassium bicarbonate with 4 liters of water. Lightly spray the leaves of plants affected by black spots, powdery mildew and other fungal diseases. In this case, potassium bicarbonate is a good substitute for soda."
