The Russian and foreign chemical industry offers a huge range of drugs to protect vegetable and berry crops from fungal infections. Fungicides are especially relevant for grapes, both for preventive purposes and to eliminate the disease. Contact, systemic and combined action agents can be used for processing.
Systemic fungicides for grape treatment
The mechanism of action of systemic fungicides is the penetration of the active substance into the affected crop, spreading through the juice and affecting the fungus “from the inside.” This is a stronger drug. It is used for grape plants that have already been infected.
Systemic fungicides can destroy mycelium, suppressing its reproduction.
Before it can take effect, the fungicide must be absorbed into the plant.
This takes from 2 to 6 hours. From the moment of spraying the grapes, they are valid for 21 days. The active substance spreads evenly over all stems, reaching the roots. 6 hours after treatment, any bad weather (rain, increased humidity, high temperature) is not dangerous.

The only significant drawback
-
the ability of the fungus to adapt to such means over time.
Systemic fungicides for grapes: Quadris, Strobi, Skor, Topaz, Falcon, Folpan.
Drug Topaz
Drug Topaz
Topaz is a systemic fungicide. Provides protection to the vineyard from mildew, rust and oidium. Of course, the most obvious and powerful effect is observed in the early stages of infection. In later cases, re-treatment may be required after 2 weeks. To treat the vineyard, take 2 ml of the drug per bucket of water.
The main advantages of this substance include:
- profitability (a little liquid is needed for processing);
- duration of action;
- efficiency;
- rapid action in the early stages of the disease;
- Possibility of use in complex processing.
Contact fungicides for grapes
This type of chemical is used for fungal infections. Most often, the disease affects such parts of the plant as: leaves, shoots that have just begun to form, grape bunches and ovaries.
The principle of action of contact fungicides for grapes is to create a shell on the surface of the plant, which protects it from various types of damage.
Fungal spores die immediately after contact with the shell. The culture remains undamaged.
Photos of contact fungicides
The advantage of contact action fungicides is that the fungus cannot adapt to the drug and develop immunity, and therefore the product is always effective.
Protection lasts on leaves and vines for 10 to 12 days, subject to dry weather.
High ambient temperatures reduce the duration of action of the chemical. Therefore, in such cases it is worth carrying out the treatment a little more often, after 10 or even 8 days.
Important!
Just 7 to 8 sprays are enough. After rain, the procedure is repeated regardless of when it was carried out.
Contact preparations for grapes are good as prevention.
There is no point in applying them to already damaged areas, since the product does not eliminate mycelium. If infected parts are found, they are removed, leaving only healthy areas of the vine, and treated.
Contact action fungicides for grapes: Shavit, Cuprozan, Fundazol, Tiovit Jet.
Treatment in spring, summer and autumn
The fungicidal treatment schedule looks like this:
- The first spraying is carried out in the spring, until the buds on the bark swell. This is necessary to protect against ticks and other pests that hibernate in the bark;
- the procedure is repeated after the first shoots and 4-5 leaves appear;
- another treatment is carried out after flowering and at the stage of formation of “peas”;
- the last stage occurs in autumn.
Attention! During flowering, the procedure is not carried out. In the autumn, the last treatment is planned no later than 20 days before harvest.
Complex fungicides
From the name itself it becomes clear that these drugs combine both contact and systemic fungicides.
They have their own application features, advantages and disadvantages.
Most of the complex fungicide preparations for processing grapes require careful and careful use, as they contain substances that are hazardous to humans. When working with such substances, be sure to protect your hands by wearing gloves. They act selectively. An undeniable advantage is the possibility of using such fungicides to treat already infected grape plants.
Photo of complex fungicide
The mechanism of operation of these drugs is that their effect occurs selectively depending on the type of fungus.
Mixed-action drugs are used for prevention and treatment. In addition, complex fungicides cope well with the appearance of spotting and infectious lesions.
Complex fungicides: Cabrio Top, Paracelsus, Acrobat, Polychom.

Complex fungicide used to combat mildew, oidium, various types of spots, anthracnose. It is considered, among other things, a high-quality, biological insecticide, and not just a fungicide, and therefore it also fights some pests. The principle of action is to create a supply of the drug on the surface of the plant, which gradually acts. This drug is not washed off by precipitation or watering.
Important!
It is the drug Cabrio Top that is recommended in cases of mass infection of vineyards with oidium or mildew.
It is used no more than 2 times per season, as it has a long-lasting effect. Thanks to this, the degree of action of toxins on grapes is reduced and therefore this fungicide is not dangerous for ripened bunches (it has time to erode).
The best fungicides in the fight against grape diseases: description, action, application
It is definitely impossible to say that one drug is better than another. Each substance specifically acts on a specific type of fungus, infection and other pathogens. Winegrowers with little experience often use complex-action preparations. It is difficult for them to identify the disease immediately. Experienced winegrowers can accurately determine what is affecting the crop and choose the most suitable and gentle fungicide for treating grapes against diseases.

Preventive measures against fungal diseases
Unfortunately, if the disease has already begun to spread throughout the grape bush, it can be very difficult to cure. Therefore, it is recommended to carry out preventive measures - preventive inspections of all areas of the bush, useful spraying and tillage.
Note!
You need to be especially careful with plants that are not resistant to diseases. They require more frequent fungicide applications and other protective measures.
It is necessary to regularly inspect the vines and leaves, promptly remove rotten and shriveled areas. The first preventive spraying is carried out immediately after removing the winter shelter before the period of swelling of the buds.
Advice!
For the first treatment, you can use 3% Bordeaux mixture, copper sulfate or any “weak” fungicide.
Sanitary pruning will allow the plant to direct its energy to the growth of healthy shoots. Removing excess branches that thicken the bush will allow air to better penetrate inside the crown, which means the risk of excessive moisture and fungus will be significantly reduced. It is also important to keep the soil clean: remove weeds that are carriers of infections in a timely manner; loosen the soil to saturate it with oxygen, apply fertilizing to increase the immunity of the grapes.
What fungicides to use for specific grape diseases
If the grapes are affected by mildew, then you should use products containing copper, for example, Bordeaux mixture.
In the fight against mildew you should use:
- Carbio Top;
- Ridomil Gold.
The fight against oidium seems to be a complex task and involves a number of therapeutic and preventive measures. Treatment of grapes with fungicides also plays an important role in the fight against oidium.
There are chemicals that help simultaneously fight mildew and grape oidium:
- Strobe;
- Vectra;
- Falcon;
- Alto Super Topaz;
- Fundazol.
If the vineyard is affected by gray rot, then you can treat it with fungicides:
- Topsin;
- Ronilan;
- Rovlan;
- Euparen;
- Sumilex.
For white and black rot of grapes, you can use the following remedies:
- Topaz;
- Captan;
- Baitan;
- Zinebom;
- Flaton;
- Bayleton.
Important!
Before use, carefully read the instructions for using fungicides for grapes.

Varieties
Grapes are susceptible to a fairly large number of fungal diseases. Oidium, gray and white rot, mildew, chlorosis, anthracnose, etc. can destroy not only the crop, but also the vineyard itself. Read about the treatment of grape chlorosis at the link.
Breeders are constantly improving the crop, developing new varieties that are resistant to certain diseases. However, this problem cannot be completely solved.
It is almost impossible to save grapes when the infection has already spread throughout the plantation. A much more effective method of combating fungi is preventive treatment of the vineyard with fungicides.
Fungicides are far from universal. For example, effective drugs against scab or powdery mildew are Tipt, Ikarus, and Topaz. But they are powerless against anthracnose. This means that spring processing, like autumn processing, must be carried out in several stages and using various means.
Treatment of the vineyard with fungicides is carried out in stages, depending on specific goals and objectives.
There is an opinion that the action of a fungicide reduces the taste of berries and is even harmful. In fact, fungicides only affect the fungus. In addition, the only alternative when infected with oidium or black rot is the complete destruction of plants.
How to spray grapes, read this material.
All types of drugs are divided into 3 main groups.
Contact
The fungus most often affects leaves, young shoots, ovaries and bunches. To prevent infection and prevent the emerging disease from spreading, contact fungicides are used.
Read about the fight against phylloxera on grapes here.
Contact preparations create a kind of protective shell on the surface of plants. Upon contact with it, the fungal spores die and the grapes remain undamaged. The fungus does not adapt to contact agents; this is the main advantage of a contact fungicide.
The “coat” created by the fungicide remains on the leaves and vines for no more than 10–12 days in the absence of rain. Too high a temperature also contributes to its faster destruction. Accordingly, the treatment must be repeated every 8–10 days. In general, 7–8 sprays are required. Moreover, if after the next treatment it rains, then the procedure will have to be repeated unscheduled.
Contact preparations do not destroy the mycelium. It makes sense to process grapes only if infected parts have been removed or not detected.
Read about gray rot on grapes here.
Examples of such fungicides are Tsineb, Khom, Folpan. Hom is an alternative to Bordeaux mixture. It protects well against infection, but is ineffective for treatment. The substance is used to prevent infection. Folpan is more effective and is also used to treat infected plants. Folpan can be used to treat the area no more than 4 times a year.
System
The principle of action of systemic fungicides is completely different. The substances penetrate the plant, spread along with the juice and fight the fungus from the inside. Such a drug is able to completely destroy the mycelium and suppress reproduction.
A systemic fungicide must be completely absorbed to begin working. This takes from 2 to 6 hours.
The drug has several important advantages:
- not only protects the plant, but also destroys the fungus;
- after treatment, the fungicide is effective for 2–3 weeks and not only on the treated surface. It protects both new shoots and leaves;
- rain or humidity are not a hindrance, the substance is not washed off;
- the number of procedures is reduced to 3 times a year.
There is also a drawback: the fungus adapts to such preparations, so fungicides of the same group are not used more than 2 times a year. Systemic compositions combine well with contact ones.
Falcon is one of the most popular systemic fungicides for the prevention of grape diseases. Price from 1000 rub. for 1 liter.
Systemic drugs include Falcon, Fundazol, Topaz. Each product has its own specialization. Thus, Falcon is most effective against oidium, and Fundazol acts against powdery mildew, scab, and snow mold.
Systemic fungicides are able to combat fungi that attack the root system of plants, such as root rot.
Complex
Such compositions combine the properties of contact and systemic ones, which, however, means combining both advantages and disadvantages. Many complex drugs require very careful handling, as they are toxic to humans.
Complex fungicides also act selectively. But their undoubted advantage is that substances of this class can be used to treat infected plants. The most common compositions include the following:
- Mikal - used for preventive treatment and for the treatment of fungus. A prerequisite is that the fungicide must be applied no later than 2-3 days after the fungus is detected;
- Shavit – fights gray and white rot, downy mildew, and infectious drying. The composition is very effective, but it must be used with extreme caution: Shavit is highly toxic, so the treatment is carried out in protective clothing and a respirator. The fungicide should not be used more than twice a year;
- Flint is effective in the fight against oidium, black rot, mildew, and rubella. Flint is low toxic, up to 3 applications per year are allowed. The duration of the drug is 8–14 days, after which it is recommended to perform the procedure using a compatible contact drug;
- Cabrio Top - its main advantage is its effectiveness against mildew and oidium at the stage of mass infection of grapes. In addition, the fungicide is used to treat anthracnose and blight. Another plus is that the drug is also effective against harmful insects. Its validity period is almost a month due to the fact that the drug can accumulate in the leaves and vines and is consumed over a long period of time. The effectiveness of the product does not change under the influence of rain and heat.
Fungicidal drug with complex effects - polychomus
This drug is from a complex group of drugs. It can protect grapes from various pathogenic microorganisms. Its active ingredients are: copper oxychloride and polycarbacin. Together, these substances act even more intensely and effectively. Treatment with this product can be carried out in any weather conditions. It is also worth noting that there will be no large financial costs. But it is very important to remember that this remedy is recommended for use only during the growing season of the crop. On average, approximately four to six treatments will be required in one season. This remedy can be replaced with the help of such means as: 1) revus; 2) polisher; 3) tilt.
Composition and action of the fungicide
The active ingredient of Kuproxat is tribasic copper sulfate, and its closest analogue is Bordeaux mixture. The fungicide has a contact effect. As a result of spraying with the working solution, the drug creates a protective film on the leaves. It prevents the penetration of fungal spores and protects plants from diseases. In addition, the drug can also be used for treatment. The active substance, once on pathogenic bacteria, blocks the respiratory system, destroys cells, leading to death.
A huge advantage of Kuproxat is its high resistance to weather conditions. The protective film formed after spraying is not washed off either during watering or during rain.
