二化螟抗药性问题逐年加重,容易爆发成灾,有必要开展研究控制其危害蔓延。试验选用6种药剂对单季稻二化螟进行防治,在危害稳定期调查各个处理的防治效果,筛选高效药剂。结果表明:10%阿维·甲虫肼悬浮剂1.2 L/hm~2对二化螟防效最好,5%丁虫腈乳油1.5 L/hm~2、5%阿维·丁虫腈乳油0.75 L/hm~2、5%阿维菌素微乳剂0.75 L/hm~2、40%三唑磷乳油0.975 L/hm~2防效一般,25%甲维·茚虫威水分散粒剂150 g/hm~2防效最差。试验筛选出了10%阿维·甲虫肼,可临时替代氯虫苯甲酰胺,有效控制二化螟危害。
Stem Borer drug resistance increased year by year, prone to disaster, it is necessary to carry out research to control the spread of its hazards. Six kinds of pesticides were used to control the single-season rice stem borer (Chilo suppressalis), and the control effect of each treatment was investigated during the period of endangering the stability, and the high-efficiency chemicals were screened. The results showed that the best effect of 10% Avicel Beetle Suspension 1.2 L / hm ~ 2 on the Stem Borer was the best, and 5% Serpulina EC 1.5 L / hm ~ 2,5% Arvine Sericin EC 0.75 L / hm ~ 2,5% Abamectin microemulsion 0.75 L / hm ~ 2,40% Triazophos 0.975 L / hm ~ 2 Control effect, 25% g / hm ~ 2 worst effect. The test screened 10% avian beetle hydrazine, can temporarily replace chlordomography benzamide, effectively control the damage of stem borer.
