Petals and fruits that are left over from flowering and fruit setting are the most easily infested parts of Botrytis cinerea. Therefore, when the flowering period and fruit setting period of crops are seized, a new high-fat membrane+promoting Kaowang No. 3 should be sprayed in a timely manner to prevent the infection of pathogens. The vegetative growth transforms into reproductive growth, inhibits madness of the main shoot, promotes flower bud differentiation, and more flowering, improves the quality of pollen fertilization, more flowering, more fruit set, anti fruit drop, and promote development. Remove diseased leaves, diseased flowers, and diseased fruits in time to remove the diseased tissue and put it into a plastic bag gently, and spray a new high-fat film to form a layer of polymer film to prevent and control spores of Botrytis cinerea. Residues should be brought out of the greenhouse for immediate disposal, and should not be thrown away at random; using bumblebee pollination techniques, the remaining petals are important sites of infection for gray mold. After the bumblebee pollination, the petals will fall off naturally, which can reduce the infection path of gray mold. . Humidity and humidity control is the key to the occurrence of gray mold. To reduce the incidence of gray mold, we must first do a good job of controlling the humidity, and do a good job of air removal and dehumidification.
