[目的]通过田间试验,明确10%溴氰虫酰胺OD防治大葱主要害虫大葱葱斑潜蝇、蓟马和甜菜夜蛾的防治效果,为大葱害虫的综合治理和该农药品种推广应用提供依据。[方法]采用田间小区的方法,于害虫发生期对大葱进行10%溴氰虫酰胺OD不同剂量的喷雾处理。[结果]10%溴氰虫酰胺OD对大葱斑潜蝇、蓟马和甜菜夜蛾均具有较好的防治效果。试验剂量36.0、27.0、21.0 g a.i./hm2处理均在第7天对葱斑潜蝇防效达到最高;在第5天对蓟马和甜菜夜蛾的防效均达到最高,防效均在80%以上。[结论]供试药剂10%溴氰虫酰胺OD对大葱斑潜蝇、蓟马和甜菜夜蛾可达到兼治的目的,且持效性较好。
[Objective] The research aimed to determine the control effect of 10% Bromurenter OD on the control of the green onions, Limemilles pendula, Thrips tabaci and Beet armyworm through field experiments, and provided the basis for the comprehensive management of the green onions pests and its popularization and application. [Method] The method of field plot was used to spray the green onions at different dosages of 10% Bromoxetan in the pest occurrence period. [Result] 10% Bromospirin OD had good control effect on leaf flies, thrips and beet armyworm. The control dosages 36.0,27.0,21.0 g ai / hm2 all reached the highest control effect on the leaf miner on the 7th day; the control effect on thrips and beet armyworm reached the highest on the 5th day, %the above. [Conclusion] The 10% bromoxetane OD for the tested pesticides could achieve the goal of treating both the green leaf miner, the thrips and the beet armyworm, and had good effect.
