为明确2 7.8%噻呋·苯醚甲悬浮剂(福赛)对水稻纹枯病的防治效果,于2013年在早稻上进行了相关防效试验。结果表明,福赛对水稻纹枯病的防效显著。在水稻发病前期,每667 m2用福赛25 g施药1次,防效达74.3%,与拿敌稳施药1次、爱苗施药2次的防效无显著差异。福赛持效期长,1次施药即能控制纹枯病为害,在纹枯病严重发生时,可酌情在水稻破口期再用药1次,其防效则更加显著。
In order to clarify the control effect of 2 7.8% thifen-phenylethanone suspending agent (Fusei) on rice sheath blight, the related control effect was tested on early rice in 2013. The results show that Fuxi race against rice sheath blight significant effect. In the early stages of rice disease, Fusai 667 m2 every 1 application of pesticides, control effect reached 74.3%, and take the enemy a stable drug application, Ai Miao 2 times the control effect was no significant difference. Fusai persistence period, a pesticide that can control sheath blight damage, sheath blight in the serious occurrence, as appropriate, re-use of rice in the breach of time 1 times, the control effect is even more significant.
