2. Pest control. In the spring, low-temperature and high-humidity diseases such as gray mold disease have been alleviated, but the temperature is slightly higher, and the diseases with less stringent humidity requirements will be aggravated, such as leaf mold, powdery mildew and root-knot nematode disease. Then there are pests, such as whitefly, aphids, and Liriomyza sativae. For these pests and diseases, early prevention and early treatment should be achieved. For leaf mold, 60% anti-mildew (carbendazim hydrochloride) 500 times solution, 25% azoxystrobin suspension 800 times solution, 25% tebuconazole 2500 can be used. ~3000 times liquid, 25% azoxystrobin 800 times solution and 2% spring leimycin 300 times liquid spray control, pay attention to alternating medication, 2 to 3 times in a row.
