Second, how to control leaf miner moths?

1. Physical control

(1) in autumn and winter, all the branches and tips of diseases and insect pests should be cut off, and the withered branches, rotten leaves, rotten fruits and weeds in the park should be burned in different places, so as to reduce the occurrence of overwintering insects.

2. Drug prevention and treatment

In the stage of unified shoot release, when the new shoot buds grow to about 5 mm, spray immediately when the germination rate is about 20%, and then spray each time at an interval of about 7 days, continuously spraying 2-3 times.

The medicament can be selected as follows: 1500-2500 times of imidacloprid wettable powder, 3000-4000 times of 1% avermectin EC, 1000-2000 times of 5% flubenzuron EC, 1500-2000 times of 5% flufenuron EC, or 3000-4000 times of 2.5% cyhalothrin EC, or 3, 000-5, 000 times of bifenthrin EC, etc.
