Spraying for prevention

The fungicide is used as a preventative against grape diseases. The bushes are sprayed at the first suspicion of the appearance of fungi. Spraying continues until there is 100% confidence that the threat of disease has passed.

The first preventive treatment is carried out until more than 4 leaves appear on the plant. Spray the second time two weeks after the first treatment. The grapes are then processed two more times at intervals of two weeks.

Processing grapes

After the first signs of grape infection appear, the vine is treated with fungicides according to a certain scheme. Preventative grape processing is held several times a season. The most optimal time for spraying is considered to be early spring.

Before flowering

Before flowering, grape bushes are sprayed 3-5 days before the inflorescences bloom. After the grapes have bloomed, they cannot be sprayed with chemicals. After the first spraying, you need to wait 14 days and re-treat the grape bushes.

During the ripening period of berries

During the period of ripening of berries, grape bushes are sprayed in extreme cases, if the disease has spread greatly and it is not possible to cope with it in other ways. Due to the high toxicity of Ridomila Gold, after spraying bushes with already ripe berries, you should not eat them for as long as possible.

Seasonal use

If signs of powdery mildew or another disease appear during the fruiting season and pose a threat to the plant and future harvest, immediate action should be taken. These include treating bushes with the chemical Ridomil Gold.
