Agricultural control. 1.Grow wisely. It is recommended to plant early-maturing varieties to avoid the occurrence of fruit flies. The maturity period of varieties in the same planting area should be consistent, and mixed planting of early, middle and late maturing varieties should be avoided to reduce the transfer of pests.

2.Clean the countryside. Remove dead branches and weeds around orchards and fruit warehouses in a timely manner; Removal of rotten fruits at ripening; After the beginning of winter, the whole garden is turned shallowly, with a depth of 5cm-10cm.
