20%啶虫脒可溶性液剂对杞柳瘿蚊的防效研究

Control Effect of 20%Acetamiprid SL Against Rhabdophaga salics

为有效控制杞柳瘿蚊危害,筛选出防治杞柳瘿蚊的理想药剂和最佳的施药剂量,本试验采用茎叶喷雾法研究20%啶虫脒可溶性液剂及其与3种化学混合农药对杞柳瘿蚊的防治效果。结果表明:20%啶虫脒可溶性液剂单剂及其与3种农药混合对杞柳瘿蚊均有很好的防治效果,其中以20%啶虫脒可溶性液剂525 mL/hm^(2)对杞柳瘿蚊的综合防治效果最好,其次是20%啶虫脒可溶性液剂375 mL/hm^(2)和20%啶虫脒可溶性液剂150 mL/hm^(2)+40%毒死蜱乳油750 g/hm^(2)。从生产成本、防治效果等因素综合考虑,推荐使用20%啶虫脒可溶性液剂375 mL/hm^(2)或20%啶虫脒可溶性液剂150 mL/hm^(2)+40%毒死蜱乳油750 g/hm^(2)防治杞柳瘿蚊。

In order to effectively control the damage of Rhabdophaga salics,and screen out the ideal agent and the best dosage for controlling Rhabdophaga salics,the stem leaf spray method was used to study the control effect of 20%acetamiprid SL and its mixture with three chemical pesticides against Rhabdophaga salics.The results showed that a single dose of 20%acetamiprid SL and its mixture with three pesticides had good control effects against Rhabdophaga salics.Among them,the comprehensive control effect of 20%acetamiprid SL 525 mL/hm^(2) was the best,followed by 20%acetamiprid SL 375 mL/hm^(2) and 20%acetamiprid SL 150mL/hm^(2)+40%chlorpyrifos EC 750 g/hm^(2).Taking into account factors such as production cost and control effect,it is recommended to use 20%acetamiprid SL 375mL/hm^(2) or 20%acetamiprid SL 150 mL/hm^(2)+40%chlorpyrifos EC 750 g/hm^(2) to control Rhabdophaga salics.
