| 摘 要： | 为筛选适合防治稻瘟病的药剂,以空育131水稻品种为试材,选用30%富米乐（900、1 200 mL·hm^-2）和40%富士一号（1 500 mL·hm^-2）药剂进行稻瘟病的田间防效试验。结果表明：30%富米乐（1 200 mL·hm^-2）效果最好,叶瘟防效为73.1%,穂颈瘟的防效达到75.5%,且能提高结实率和干粒重,产量达到9 490.5 kg·hm^-2,比清水对照增产17.9%。

| Abstract: | Taking the rice variety of Kongyu 131 as material,30% funile（27% Isoprothiolane EC＋3% hexaconazole EC）（900、1 200 mL·hm^-2） and 40% Isoprothiolane EC（1 500 mL·hm^-2） were tested to study the effect of different pesticides against rice blast.The results showed that：the control effect of 30%fumile（27%Isoprothiolane EC ＋3%hexaconazole EC）（1 200 mL·hm^-2）was the best among the three pesticides,the control efficiency of leaf blast was 73.1% and net blast achieved 75.5%.Furthermore,the treatment could increase seed-setting rate and 1000-grain weight,the yield of 30%fumile（1 200 mL·hm^-2）treatment reached 9 490.5 kg·hm^-2,increasing 17.9% compared with CK. |
