What pesticides are used to control corn pests?

1. Corn borer: The straw is crushed and returned to the field to reduce the base number of insect sources; the overwintering adults are trapped with insecticidal lamps combined with attractants during the emergence period; At the end of the heart leaves, spray biological pesticides such as Bacillus thuringiensis and Beauveria bassiana, or use pesticides such as tetrachlorantraniliprole, chlorantraniliprole, beta-cyhalothrin, and Emamectin benzoate.

2. Underground pests and thrips, aphids, planthoppers, beet armyworm, armyworm, cotton bollworm and other seedling-stage pests: use seed coating agents containing thiamethoxam, imidacloprid, chlorantraniliprole, cyantraniliprole, etc. Seed coating is performed. 

3. Corn sheath blight: choose disease-resistant varieties, and plant them reasonably densely. In the early stage of the disease, peel off the diseased leaf sheaths at the base of the stem, and spray the biological pesticide Jinggangmycin A, or use fungicides such as Sclerotium, Diniconazole, and Mancozeb to spray, and spray again every 7 to 10 days depending on the disease.

4. Corn aphids: During the corn tasseling period, spray thiamethoxam, imidacloprid, pymetrozine and other chemicals in the early stage of aphid bloom.
