Viral disease: In the early stage, timely control of aphids can be sprayed with 10% imidacloprid 1500 times solution. It was found that the condition was timely sprayed with 20% virus A wettable powder 400 times liquid or 1.5% phytopathogenic emulsion 500 times liquid, once every 7 days, and even 2-3 times.

Epidemic disease: timely use in the early stage of the disease, 75% chlorothalonil wettable powder 600 times solution, 64% antivirus WP WP 400 times solution, 72% gram dew 800 times solution, 70% mancozeb 400 times solution, interval 7-10 days, even 2-3 times, can effectively control the disease epidemic.

Anthrax: 75% chlorothalonil 600 times solution, 70% methyl thiophanate 400 times solution, 80% anthrax fumei 600-800 times solution, spray once every 7-10 days, even 2-3 times.

Helicoverpa armigera, beet armyworm, and cabbage caterpillar: 10 insects in a timely manner. 52.25% agricultural land 1000 times liquid, beta-cypermethrin and phoxim 1:1 mixed with 1000 times liquid, spray.
