Before flowering, it is mainly used to control aphids and viral diseases. After fruit set, it is mainly to prevent cotton bollworm and late blight. Before the seedling stage and before flowering, it can be prevented once every 7 to 10 days. The pests and diseases such as aphids, late blight and gray mold can be prevented by using Kuailing or Kuike, and it can be prevented from the seedling stage. Cotton bollworm, cabbage caterpillar and other pests can be used 2000 times liquid mist. Liriomyza sativae can be controlled with 40% green vegetable emulsifiable concentrate 1000 times.
