摘要
为明确不同药剂对水稻二化螟防治效果及对水稻生长的安全性,以清水为对照,选择5%氯虫苯甲酰胺悬浮剂、5%甲氨基阿维菌素苯甲酸盐微乳剂、19.4%甲维·氯虫可分散油悬浮剂、26%阿维·茚虫威悬浮剂和34%乙多·甲氧虫悬浮剂5种药剂,分别在桃源县的早稻和晚稻上对二化螟进行田间防治.结果表明,5种药剂均对水稻二化螟具有一定的防效,且均对水稻生长安全,其中19.4%甲维·氯虫可分散油悬浮剂处理的防治效果最好,在早稻和晚稻上的防治效果分别达到93.15%和90.44%.生产中,推荐使用19.4%甲维·氯虫可分散油悬浮剂防治水稻二化螟.
Abstract
In order to determine the control effect of different insecticides on rice Chilo suppressalis and the safety of rice growth,five insecticides were selected to control rice Chilo suppressalis on early rice and late rice in Taoyuan County.The results showed that all the five agents had certain control effect on rice borer and were safe for rice growth.In production,it is recommended to use a dispersible oil suspension of 19.4%megamyclonalis to control rice Chilo suppressalis.
