摘要
[目的]研究40%溴氰虫酰胺·吡蚜酮WG对烟粉虱的防治效果及有效剂量,为农药登记及示范推广提供科学依据。[方法]按照田间药效试验方法,进行不同剂量40%溴氰虫酰胺·吡蚜酮WG对一品红烟粉虱的防治效果比较。[结果]40%溴氰虫酰胺·吡蚜酮WG对烟粉虱成虫有较好的防治效果,在280~480 g a.i./hm2+0.1%有机硅的剂量下,处理后21 d的防治效果达到85%以上;但40%溴氰虫酰胺·吡蚜酮WG对烟粉虱若虫的效果较差。[结论]40%溴氰虫酰胺·吡蚜酮WG可以作为防治一品红烟粉虱成虫的有效药剂。
[Aims] This paper aims to test the effective dose and control effects of cyantraniliprole·pymctrozine 40% WG to Bemisia tabaci of poinsettia in pot experiment, and provide a scientific basis for pesticide registration and demonstration promotion. [Methods] The control efficacy comparative test of cyantraniliprole,pymetrozine 40% WG in pot trial at different doses against B. tabaci were studied according to guidelines on efficacy evaluation of pesticides. The control effects of cyantranilipmle .pymetrozine 40% WG on B. tabaci were conducted by greenhouse trials. [Results] The cyantmniliprole ·pymetrozinc 40% WG had good control effects on adult at 280-480 g a.i./ha+0.1% silicone adjuvant with more than 85% control aRer 21 d. The result of pot trials also showed that cyantraniliprolc · pymctrozinc 40% WG gave bad control effect against the larva or prcpupa ofB. tabaci. [Conclusions] Cyantraniliprolc- pymctrozine 40% WG could be used to control the adults of B. tabaci of poinsettia effectively.
