During the grape bud stage, for vineyards with serious branch diseases, the dead trees should be dug up in time, and biological and chemical pesticides such as etherstrobin, difenoconazole or Bacillus amylolique should be used to disinfect the soil around the dead trees, and the healthy plants near the dead trees and the diseased plants in the field should be irrigated with chemicals.
During the leaf development stage, downy mildew and powdery mildew can be mainly prevented, and copper preparations such as Bordeaux liquid, mancozeb, amino-oligosaccharides or eugenol can be sprayed 1-2 times. It is necessary to remove the sprouts and redundant side tips in time. The main pests in this period are leafhoppers, green blind bugs, jointed gall mites, etc., and insecticides such as halodioxapyr and acaricides can be sprayed once each plant to prevent leaf pests and mites. When the brown shell of A. orientalisa is found on the branches, the shell should be removed with a stiff brush and the whole plant should be sprayed with thiamethoxam once to control it.
