通过75%咪锰·苯醚甲可湿性粉剂450,600,750 g·hm-2,24%噻呋酰胺悬浮剂225 mL·hm-2(对照),75%肟菌·戊唑醇水分散粒剂150 g·hm-2(对照)及空白对照等6组不同处理对水稻纹枯病与稻曲病的防治效果和对水稻的保产增产效果试验,结果表明,咪锰·苯醚甲在水稻后期应用,对水稻生长安全及水稻纹枯病、稻曲病具有理想的防治效果,同时对水稻具有一定的健苗增产作用,其综合效果与对照药剂噻呋酰胺、肟菌·戊唑醇无显著差异,可作为防治水稻纹枯病、稻曲病用药在生产上推广应用,建议75%咪锰·苯醚甲可湿性粉剂使用剂量600～750 g·hm-2。
Antimicrobial agents were prepared by mixing 75% imidacloprid WP 450,600,750 g-hm-2,24% thifluzamide 225 ml-hm-2 (control), 150 g · Control effect of hm-2 (control) and blank control on the control of rice sheath blight and rice false smut and the yield-increasing effect on the yield of rice. The results showed that the application of imidacloprid in late rice , Which has good control effects on rice growth safety, rice sheath blight and rice false smut, and has the effect of increasing seedling yield on rice in the same time. The combined effect has no significant difference with the control drugs thifluzamide and oxitibacterium tebuconazole , Can be used as rice sheath blight, rice false smut drug in the production of the promotion and application of the proposed 75% imidacloprid WP use of the dose of 600 ~ 750 g · hm-2.
