摘要
试验结果表明,防治稻纵卷叶螟2龄期防效90.29%,1龄期防效88.71%,3龄期防效66.67%,4龄期防效46.18%。防治水稻稻纵卷叶螟以2龄幼虫期防治效果最佳。几种药剂以30%茚虫威乳油防效92.65%最佳;其次为20%康宽悬浮剂,防效达89.55%;3%甲维盐(微乳),防效达85.10%;48%毒死蜱乳油,防效达83.65%;29%杀虫双水剂,防效82.56%。
The results showed that the control effect of the 2nd,1st,3rd and 4th instars of Cnaphalocrocis medinalis was 90.29%,88.71%,66.67%and 46.18%respectively.The control effect of 2 instar larva stage was the best for Cnaphalocrocis Medinalis.The results showed that 30%indoxacarb EC had the best control effect of 92.65%,followed by 20%kangkuan SC(89.55%),3%Emamectin(microemulsion)of 85.10%,48%chlorpyrifos EC(83.65%),29%dimehypo water solution(82.56%).
