[目的]明确烯肟菌胺和噻呋酰胺在防治水稻纹枯病上的可混性。[方法]采用室内联合毒力、盆栽试验法。[结果]室内联合毒力试验结果表明:烯肟菌胺和噻呋酰胺5个配比的供试混剂表现为明显的增效作用,其中以5∶1的配比抑菌效果最好;盆栽试验表明:相同质量浓度下,30%烯肟菌胺与噻呋酰胺悬浮剂5#对水稻纹枯病的防效高于其他配方。[结论]30%烯肟菌胺·噻呋酰胺悬浮剂对水稻纹枯病具有良好的防治效果,且对水稻生长安全。
[Objective] The research aimed to clarify the miscibility of netilmicin and thifluzamide in the control of rice sheath blight. [Method] Indoor combined virulence and pot experiment were used. [Result] The results of indoor combined virulence test showed that the mixture of five components of the mixture of netilmicin and thifluzamide exhibited obvious synergistic effects, of which 5:1 was the best antibacterial effect. Pot experiments showed that the control effect of 30% thio-terbinafine and thifluzamide SC 5 # on sheath blight was higher than that of other formulations at the same concentration. [Conclusion] The suspension of 30% thiamethoxam-thifluzamide had good control effect on rice sheath blight and was safe for rice growth.
