Please explain and guide how to prevent and control themThe key targets for prevention and control of rice pests and diseases in August are rice false smut, neck blast, and bacterial leaf streak, while also controlling rice planthoppers and rice leaf folders. You can refer to the following methods for prevention and control:
1. One week before rice booting (when the boot swells), you can choose 12% jinggangmycin·difenoconazole wettable powder at 30-40 grams per mu, or 20% jinggangmycin·diniconazole·tricyclazole wettable powder at 15-20 grams per mu, plus 40%-48% chlorpyrifos (Lorsban, Tongyishun) emulsifiable concentrate at 100 milliliters per mu, mix with water and spray for control. Apply once every 7-10 days, for 2 consecutive applications.
2. In areas where bacterial leaf streak occurs, you can choose 50% chlorobromoisocyanuric acid at 20-30 grams mixed with 15 kg of water, or 20% zinc thiazole at 25-40 grams per mu mixed with 15 kg of water for spray control.
