At present, the most effective way to prevent grape locust plague prevention is to set up a flood control net at the top of the canopy. For gardens that do not use flood prevention nets, in case of disasters, they should promptly carry out remedial work. The specific measures are as follows:
1. The vineyard cleans up the racks, places branches and vines on the rack surface, protects the existing leaves, strengthens the management of the shoots on the ground, promotes and cultivates new-born shoots, trims reasonably, removes or shortly cuts and shoots. Broken, split new shoots should be cut at the wound to facilitate wound healing.
2. The fruit management timely removes the severely injured fruit that is injured by ice, and then adjusts the load of the tree body according to the tree body injury situation, in order to facilitate the restoration of tree vigor as soon as possible.
3. Prevention of Diseases and Insect Pests The occurrence of pests and diseases is often aggravated after the disaster. Therefore, it is necessary to protect them with pesticides in time to prevent the spread of diseases and leaf diseases. Use a protective agent (such as Baomei Fumei Double, Wanbao Lu, etc.) +40% fluorosiliconazole 8000 times as soon as possible after the disaster to spray the whole garden. After 3 days, use 35% Difenoconazole 3000 times. In the later period, disease management will be strengthened to prevent falling leaves in advance.
