Scientific application of pesticides: According to 100-plants of cotton, which have 8-10 first-instar larvae as control indicators, first consider using biological pesticides such as Bt, 2% avermectin, 25% diflubenzuron, 20% tebufenozide, and insecticide list. And pesticides that are less lethal to natural enemies such as Sadan, 2.5% lambda-cyhalothrin, etc.
