摘要
利用田间喷雾方法,探讨了不同药剂对亚洲玉米螟的防治效果。小区试验结果表明:以40%氯虫·噻虫嗪水分散粒剂防治效果最好,从被害株率和活虫率来看,防治效果分别为93.23%和93.68%。并利用高秆喷雾机械对40%氯虫·噻虫嗪水分散粒剂进行了田间防治玉米螟示范。大田试验结果表明:以40%氯虫·噻虫嗪水分散粒剂防治效果最好,从被害株率和活虫率来看,防治效果分别为92.93%和93.22%,比对照增产7.71%。该药具有胃毒、内吸作用,毒性低的特点,是当前防治玉米螟的理想药剂。
The control effect of spraying in the field of different chemicals against Asian Corn Borer was studied. The results showed that 40% Chlorantraniliprole ＋ Thiamethoxam had best control effect, which was 93.23% and 93.68% of infected rate of plants and living insect rate. Similar results were obtained in large scale demonstration test using high arm sprayer, which control effect was 92.93% and 93.22% of infected rate of plants and living insect rate. Its yield was 7.71% higher than that of control. The chemical has stomach poison and interior suction effect and low toxicity, is the rational agent for the control against Asian Corn Borer.
