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。
Using field spraying method, the effects of different agents on the control of Asian corn borer were discussed. The plot test results showed that the control effect of 40% chlorantraniliproxen water dispersible granules was the best, and the control effect was 93.23% and 93.68%, respectively. And the use of high-stalk spray machinery on the 40% chlorantraniliproximate water dispersible granules field corn borer demonstration. The results of the field trial showed that the control effect of 40% chlorantraniliproximate water dispersible granules was the best, and the control effect was 92.93% and 93.22% respectively, which was 7.71% more than the control. The medicine has the characteristics of stomach poisoning, internal absorption and low toxicity and is the ideal medicament for preventing and curing corn borer.
