[目的]明确20%灭蝇胺·噻虫胺悬浮剂不同剂量对韭菜迟眼蕈蚊幼虫的防治效果,为药剂生产及田间应用提供科学依据。[方法]采用灌根法测定不同剂量20%灭蝇胺·噻虫胺悬浮剂对韭蛆的田间防效。[结果]对韭菜灌根1次,14 d后各处理的20%灭蝇胺·噻虫胺悬浮剂900、1350、1800 g a.i./hm~2对韭菜迟眼蕈蚊幼虫的防效均达90%以上。[结论]20%灭蝇胺·噻虫胺悬浮剂900~1800 g a.i./hm~2的对韭蛆防效好,建议推广使用。
[Objective] The research aimed to clarify the effect of different dosages of 20% cyromazine and clothianidin suspension on larvae of larvae of M. armigera and provide a scientific basis for the production of pharmaceuticals and field application. [Method] The field control effects of 20% cyromazine and clothianidin suspension on leek maggot were determined by the method of rooting. [Result] The control effect of 900, 1350 and 1800 g ai / hm ~ 2 of 20% of cyprodin and clothianidin suspension on the larvae More than 90. [Conclusion] The control effect of 20% cyromazine and clothianidin suspension 900 ~ 1800 g a.i./hm ~ 2 on leek maggots is good, and it is recommended to promote the use.
