Leafminers are most severely damaged during the summer and autumn shoots in July-September. For leaf miners, it is best to spray about 5 mm after the shoots are removed. It is possible to use 3% avermectin EC 5000 times, or 3% acetate EC 3000 times, or 480 g/L chlorpyrifos. Emulsion 1000 times, or 25 g/L lambda-cyhalothrin 2500 times, spraying once every 10 days for 2-3 times. Spring shoots are the places where the nutrient supply of the preserved fruits is preserved. To cultivate spring shoots, some quick-effect fertilizers should be applied to promote the growth of spring shoots, and sprays should be fully sprayed before flowering to eliminate red spiders and other insect pests that affect young shoots, such as locusts and leaf miners.
