Fungal diseases affect grain crops, vegetables, vineyards and flower beds. The easiest way is to prevent the development of the disease at an early stage. Preventive treatments based on the drug Bravo protect the surface of plants from the spread of fungus.
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;
