室内毒力测定结果表明:嘧菌酯与己唑醇以2∶3、1∶2、1∶3配比均可,其中嘧菌酯与己唑醇以1∶2复配的制剂EC50为0.00791μg/mL,SR50为1.55。田间防效试验表明:24%嘧菌.己唑醇SC 375 mL/hm2、450 mL/hm2与24%噻呋酰胺SC 360mL/hm2,三处理之间差异不显著,但均与24%嘧菌·己唑醇SC 300 mL/hm2、10%己唑醇SC 750 mL/hm2、250 g/L嘧菌酯SC375 mL/hm2差异显著或极显著。24%嘧菌·己唑醇SC 375～450 mL/hm2(推荐用量)与24%噻呋酰胺SC 360 mL/hm2的防效相当,但成本低,性价比高,同时能兼治稻曲病、稻瘟病,达到一药多治效果,对水稻生育安全,无药害,且能使水稻叶片增绿,增强生长势等作用。
Indoor toxicity test results showed that: azoxystrobin and hexaconazole 2: 3,1: 2,1: 3 ratio can be, wherein the azoxystrobin and hexaconazole 1: 2 formulation EC50 0.00791 μg / mL, SR50 is 1.55. Field control experiments showed that there was no significant difference between 24% azoxystrobin and hexaconazole SC 375 mL / hm2,450 mL / hm2 and 24% thifluzamide SC 360 mL / hm2, · Hexaconazole SC 300 mL / hm2, 10% Hexaconazole SC 750 mL / hm2, 250 g / L Azoxystrobin SC375 mL / hm2 The difference was significant or very significant. 24% azoxystrobin SC 375 ~ 450 mL / hm2 (recommended dosage) is equivalent to 24% thifluzamide SC 360 mL / hm2, but its cost is low and its cost performance is high. Blast disease, to achieve a drug effect of multiple treatment, the safety of rice growth, no pesticides, and can make green rice leaves, and enhance the role of growth potential.
