Instructions for use of Bravo fungicide, composition and release form of the product

Composition, purpose and release form of Bravo fungicide

The main component of the Bravo fungicide is the low-toxic pesticide Chlorothalonil, which has the main functions of combating fungal spores. After spraying, the product lingers on the foliage for a long time and does not allow fungal cells to germinate, which prevents infection.

The pesticide content in the product is 0.5 kg per liter of product. The product is available in the form of a suspension. Plastic packaging contains 20, 100 ml or 1-10 liters. Used in the form of a concentrated solution.

The fungicide has a shelf life of 3 years at temperatures from minus 5° to plus 35°.

Features of the fungicide

Bravo is a contact fungicide with a protective effect. It contains chlorothalonil, the content of which is 500 g per 1 liter of the drug.

Chlorothalonil is a substance of low toxicity that can cope with various diseases. The substance remains on the surface of the leaves for a long time and prevents the germination of fungal cells. As a result, pathogenic microorganisms lose their ability to penetrate plant tissue.

Within 5-40 days, the active substance disintegrates in the soil into safe components. However, in water, chlorothalonil can remain in a permanent form for a long time.

The drug Bravo is effective against the following diseases:

• peronosporosis;
• late blight;
• Alternaria blight;
• diseases of the ear and leaves of grain crops.

Fungicide Bravo is supplied in the form of a liquid, creamy suspension. The product is used as a concentrated solution. The protective effect lasts from 7 to 14 days.

The drug is sold in plastic containers of 20 ml, 100 ml, 1 l, 5 l and 10 l. The product is compatible with other fungicides and insecticides. Before use in tank mixtures, drugs are checked for compatibility.

Operating principle

In addition to the pesticide chlorothalonil, Bravo contains additional substances that regulate the distribution of the fungicide over the surface of the plant and ensure its adhesion. A protective layer is created that prevents the fungus from reaching the culture tissues.

Attention! Fungicide Bravo performs a protective function, but does not cure.

Description of the drug

Bravo is a protective fungicide. It is not able to overcome an infection that has already spread, but it firmly protects vegetable plants from pathogens entering them.

The drug contains chlorothalonil (500 grams per 1 liter) - a highly effective and low-toxic pesticide of the chloronitrile class. It is used as the basis for many drugs aimed at combating pathogens of various crop diseases.

The preparative form of the fungicide contains special “adhesives” with the help of which the solution is evenly distributed over the surface of the leaf plates and adheres to them even under the influence of rain, aggressive ultraviolet radiation and winds. The active substance remains on the surface of leaves and stems for a long time, forming a thin but dense protective film through which spores cannot penetrate. Fungal cells cannot grow inside the plant, their development gradually stops and soon the infection subsides.

The drug is absolutely harmless to plants and soil microorganisms, as it decomposes in the soil into safe compounds within 45 days. However, in water, chlorothalonil remains in its original form and already poses a danger to mammals that will use the water for drinking.

Over many years of practice, the high effectiveness of the fungicide in the fight against diseases such as:

• late blight;
• Alternaria blight;
• peronosporosis;
• diseases of the ear and leaves of grain crops.

Chlorothalonil is a crystalline white powder. In Bravo, it is converted into a thick whitish suspension, which is diluted in water. A concentrated working solution is prepared from the viscous liquid, which is used to treat the plantings, after diluting it many times in clean water.

HOW BRAVO WORKS

BRAVO, KS is a contact fungicide with pronounced protective properties that prevents infection of the crop by fungal diseases. Since BRAVO, KS does not have medicinal properties, the drug should be used before the onset of infection. There is no risk of developing resistance to the drug due to the multisite mechanism of action.

BRAVO – SPECIFIC RESULT

BRAVO, CS prevents the disease by stopping the development of the pathogen in the early stages of infection, i.e. at the stage of germination of spores. This means that the plant does not need to expend energy to activate its natural defense mechanisms to fight the disease. Instead, the plant's energy is directed toward producing healthy foliage, resulting in increased yield and improved marketability.

UNIQUE PREPARATION FORM

The preparative form of the fungicide BRAVO, KS was created using unique technologies. It contains a special combination of adhesives and surfactants that guarantee maximum initial distribution on the leaf surface and excellent adhesion, resistant even to heavy rain - qualities that prevent infection by fungal diseases. Tests show that BRAVO, KS inhibits the development of spores even after 265 mm of precipitation. In addition, BRAVO, KS has shown excellent compatibility with a wide range of potential partners in tank mixtures.

Drop distribution on the treated sheet before and after precipitation is 10 mm/h. Comparison with analogues based on chlorothalonil.

Application regulations

Purpose: BRAVO is a broad-spectrum contact fungicide with pronounced protective properties, effective when used prophylactically against many fungal diseases of potatoes, vegetables and grain crops.

Directions for use: use the drug in strict accordance with these recommendations.

Compatibility with other pesticides: BRAVO, KS is compatible in tank mixtures with most insecticides and fungicides. However, in each specific case, mixed drugs should be checked for compatibility. Tank mixtures with herbicides are not recommended due to inconsistent timing of application. Do not mix concentrated formulations with each other!

Period of protective action: Varies from 7-14 days to 3 weeks, depending on the crop, infectious load, weather conditions and agricultural technology adopted on the farm.

Speed ​​of impact: BRAVO, KS destroys pathogen spores at the moment of their germination (i.e., acts in this case almost instantly).

Application technology: The cleanliness of the tank, main pipelines and tips, as well as the serviceability of the entire sprayer is checked before starting protective work. Then the quantity and uniformity of water supply through the tips is determined and compared with calculated data on the consumption of working fluid per 1 ha. Spraying is carried out in the morning or evening hours in calm weather, preventing the product from drifting onto neighboring crops.

Use fungicide BRAVO, KS prophylactically. Begin treatments under conditions favorable for the development and spread of the disease, but before the crop becomes infected; if necessary, repeat treatments at intervals of 7-10 days. If the crop is already infected, it is recommended to carry out the first treatment with a curative fungicide. To achieve maximum protective effect, adjust the spray equipment to fine and medium spray. The consumption rate of the working solution should be sufficient to completely wet the entire leaf surface. Increase the consumption rate of the working solution depending on the leaf surface area of ​​the crop being protected. Do not allow the working solution to drain from the treated sheet surface! The dose rate of the drug depends on the culture, type of pathogen and the presence of factors contributing to the development and spread of infection. Use higher rates of application of the drug BRAVO, KS and reduce the interval between treatments during intensive crop growth (to protect young leaves and shoots) and under conditions favorable for the development and spread of the pathogen.

Before using the drug, stir the contents of the canister. After finishing work with the BRAVO, KS preparation, thoroughly rinse the sprayer and spraying equipment.

Procedure for preparing the working fluid: fill ½ of the sprayer tank with clean water. Turn on the mixer, add the calculated and measured amount of the drug and continue filling the sprayer tank while stirring. Rinse the canister (if empty) with clean water and pour it into the sprayer tank, repeat this procedure three times. Continue stirring during processing to ensure uniformity of the working mixture. If BRAVO, KS is used in a tank mixture with other drugs, add the drugs to the water in the sprayer tank in the following order: *VDG > SP > BRAVO, KS > CE (* - if a component in a water-soluble package is used in a tank mixture, dissolve this drug first in the sprayer tank). The working solution must be used on the day of preparation.

Phytotoxicity: When using the drug in strict accordance with the recommendations developed by the company, there is no risk of phytotoxicity.

Possibility of resistance occurrence: Practically absent, subject to strict adherence to the recommendations developed by the company. Fungicide BRAVO, KS can be used in tank mixtures with other fungicides to prevent the emergence of resistance in pathogens to single-site fungicides.

The fungicide is intended for preventive measures, therefore the first spraying is carried out when the fungal disease is at the apogee of development, but infection of cultivated plants has not yet begun. A week later, the treatment is repeated when necessary. If the plant has become infected, choose a curative fungicide.

The best hours for spraying are early morning or evening, with a maximum wind speed of 4-5 meters per second.

Wheat

The culture is susceptible to diseases:

• powdery mildew;
• rust;
• septoria.

For safety reasons, spray twice a season, with an interval of one and a half months. 300 liters of solution containing 2.5 liters of product are consumed per 1 hectare.

Barley

To protect a cultivated plant from rust (stem, dwarf), spotting and powdery mildew, one treatment per season is recommended at the stage of mild or moderate disease. To prepare 300 liters of working solution, take 2.5 liters of fungicide per 1 hectare.

Potato

The culture is threatened by late blight and alternaria. Spray potatoes 3 times per season. The first procedure is carried out if there are signs of the disease. The treatment is repeated after a week and a half. For 1 hectare, 400 liters of solution containing 2.5 liters of fungicide are consumed.

Tomatoes

Tomatoes are afraid of the diseases late blight and brown spot. To prevent their development, use 3 liters of product per 500 liters of working fluid. According to the instructions, carry out 3 sprayings with a difference of 10 days. The first procedure is performed under conditions favorable for the formation of diseases (high humidity, low temperatures, dense plantings).

Grape

Grapes are often infected with the following diseases:

• oidium;
• mildew;
• anthracnose.

To avoid damage, bushes are treated with Bravo. Combine 10 liters of water and 25 g of product. Per 100 sq. m account for 4-5 liters of such a solution. Grapes are sprayed in early spring. But the last 3 weeks before harvesting are not treated with fungicide.

Onion

The fungus peronosporosis, which appears during the rainy season, is terrible for the crop. At the first signs of disease, onion processing begins and continues 3 times per season, every tenth day. Consumption per 1 hectare: 3 liters of product per 350 liters of working solution.

Important! Fruit trees are treated with Bravo fungicide against scab and alternation blight. Apple trees and apricots are sprayed with a solution prepared from 20 ml of suspension per 10 liters of water.

Reviews from gardeners

Elena, 32 years old, Perm

Last year the lilies suffered greatly from fusarium wilt. To combat the disease, a contact fungicide is needed. After studying various sources, I settled on the Bravo fungicide. According to reviews, the product has a good preventive effect. The drug turned out to be very effective; after a series of treatments, no new signs of the disease appeared. In the future I plan to use the solution for preventive purposes.

Anna, 43 years old, Ryazan

I use Bravo fungicide only to prevent diseases before their signs appear. I process potatoes and tomatoes. To do this, I make a solution to which I add the fungicides Bravo and Skor. I start spraying when there is a lot of rainfall. In such conditions, diseases spread very quickly. For treatment I choose more potent drugs.

Oleg, 55 years old, Stavropol

My vineyard most often suffers from mildew. I begin protecting bushes from damage early. Before the buds open, I treat the plantings with a contact fungicide. I add 20 g of the drug to 10 liters of water. I spray the plants in the evening to avoid exposure to sunlight. If signs of disease have already appeared on the grapes, it is better to additionally use systemic remedies.

Precautionary measures

A person working with a fungicide and not following safety precautions may become poisoned. It is necessary to wear a protective mask, gloves, and goggles. If the product gets on the skin, remove the drops with a cotton pad or napkin, and wash the skin area with soap. If the eyes are affected, rinse them with running water for 10 minutes.

In case of fungicide poisoning, a person is provided with a flow of fresh air, a large volume of water, along with activated carbon. And they call service 03.

What to combine with Bravo

The fungicide is more effective when combined with other chemicals. The drug can be mixed not only with systemic and contact fungicides, but also with insecticides. However, it is undesirable to use Bravo with herbicides, since they have the same treatment period, and the aggressive chemical composition of both drugs can negatively affect plant development.

Analogs
