Clean up the diseased plants in the field. During the growth period, the diseased plants should be removed, burned or buried in the soil in time. During the harvest season, when harvested, the general garden will be sprayed with a tree general, and the Qingyuan will be disinfected to prevent the spread of sclerotia.
Pick up the bad disk. After the harvest, it is best to organize the manpower to pick up the bad plates and concentrate on the field to burn and bury them. This is one of the important measures to reduce the source of bacteria.
Chemical control. According to the high incidence of disease in previous years, it can be effectively sprayed with targeted drug + plant cell immune factor at the end of flowering at the end of flowering and 10 days after flowering to enhance plant stress resistance and break viral DNA. Apoptosis. Strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote positive energy ecological growth of plants.
Deeply destroy the seedlings. Deep soiling can bury the sclerotium into the soil layer 7 cm. If it is over 20 cm deep in the fall, it can control the sclerotia transmission in the coming year.
