It is expected that corn pests and diseases will occur, and the opportunity for these pesticide products is coming!

Corn top rot

Chemical control: Once the diseased plants are found, pull them out in time, and use thiazolin copper, thiazole zinc, chlorobromoisocyanuric acid and other chemicals to control them, and they can also be used together with calcium fertilizer. At the same time, some foliar fertilizer can be added to enhance the photosynthesis of crops and improve stress resistance.

Corn brown spot

Chemical control: It is recommended to use triazole fungicides such as tebuconazole, econazole, difenoconazole, propiconazole, azoxystrobin, trifloxystrobin, thiophanate-methyl, carbendazim, chlorothalonil etc.

Corn rust

Pyraclostrobin can be sprayed at the trumpet-mouth stage, and pyraclostrobin can be sprayed on the 7th to 12th leaves. Hexaconazole, econazole, picoxystrobin, tebuconazole, propiconazole, triadimefon, kysstrobin, difenoconazole, benzopropiconazole, zinc zinc and other agents can also be used Alternate spray 

treatments.

Fall armyworm

Chemical control: Spinosad, Bacillus thuringiensis, Bacillus brevius, emamectin benzoate, emaminyl indoxacarb, chlorantraniliprole and other biological agents and high-efficiency and low-toxicity pesticides can be used.

Corn borer

Chemical control: The best control time for corn borer is before the 3rd instar, and beta-cyhalothrin, deltamethrin, chlorantraniliprole, emamectin benzoate, flubendiamide, phoxim, Bacillus thuringiensis and other agents can be used Prevention and treatment.
