摘　　要：The prevention and control effect of 35% thiamethoxam-prochloraz FS to rice thrips and rice bakanae disease and its influence on the quality of rice seedlings were studied. The results show that when 100 kg of rice seeds were coated with 200 g of 35% thiamethoxam-prochloraz FS,the control effects to rice thrips were 93.0% and 84.7% 15 and 20 days after sowing, and the control effect to rice bakanae disease was 90.8% 30 days after sowing. As 100 kg of rice seeds were coated with 250 g of 35% thiamethoxam-prochloraz FS, the control effects to rice thrips were 98.2% and 94.9% 15 and 20 days after sowing, and the control ef- fect to rice bakanae disease was 94.6% 30 days after sowing. 35% thiamethoxam- prochloraz FS is safe to rice seedlings and can effectively promote the growth of rice seedlings.田间测定了35%噻·咪FS对水稻蓟马、水稻恶苗病的防治效果和对秧苗素质的影响。结果表明,35%噻·咪FS 200 g/100 kg包衣,播后15、20 d对水稻蓟马的防效分别为93.0%、84.7%,播后30d对水稻恶苗病的防效为90.8%,35%噻·咪FS 250 g/100 kg包衣,播后15、20 d对水稻蓟马的防效分别为98.2%、94.9%,播后30 d对水稻恶苗病的防效为94.6%,两者均对水稻秧苗安全无药害,且能够有效促进秧苗的生长。
