If it is the pesticides and herbicides sprayed on the ground, it should be irrigated in time to rinse the residual pesticides in the soil, which can greatly alleviate the drug damage of grapes in this way. Or spray propionyl rutin lactone water agent or sea elves, can also alleviate the drug damage.
2. Rational use of drugs

The management of grape planting should be strengthened and strong trees should be cultivated in order to improve the drug resistance of grape. After the drug damage is relieved, fertilizer and water should be strengthened to promote plant recovery as soon as possible. For the already small area of drug damage, the damaged leaves or fruits can be removed, so as not to give the bacteria the opportunity to take advantage of the opportunity. If it is a large area of drug damage, it is necessary to do a good job in the prevention and control of diseases and insect pests while alleviating the drug damage.
