摘要
用江苏省淮安市7种常用防治螟虫药剂:90%杀虫单,40%毒死蜱,5%锐劲特,汇力,1.8%阿维菌素,虫无影、立克灵进行了田间防治螟虫试验,结果表明:1.8%阿维菌素EC 450 ml/hm2防治效果最差,保苗效果为85.83%;利克灵(25%毒死蜱.三唑磷)EC1 200 ml/hm2防治效果最好,保苗效果为96.57%;而杀虫单对螟虫防治效果下降可能与螟虫对该类药剂产生抗性或该类药剂在该地区的使用频率过高有关。
In this paper,the result of the field test on controlling Chilo suppressalis showed that the best pesticide was Likeling （the main component was chlorpyrifos and triazophos） under 180 ml （ai）/ha usage with 96.57 % seedling protection effect. And the worst pesticide was abamectin under 810 g （al）/ha usage with 85.83 % seedling protection effect. The test also showed that the resistance of Chilo suppressalis or the usage frequency of Shachongdan might cause the decrease of the pesticide control effect.
