树干注药对悬铃木方翅网蝽防效的研究

Study on control effect of trunk injection for Corythucha ciliate

研究用10%吡虫啉可湿性粉剂、1.8%阿维菌素乳油、5.7%甲维盐乳油、30%乙酰甲胺磷乳油、18%杀虫双水剂5种不同的药剂单一或混配药剂树干注药后对悬铃木方翅网蝽的防治效果。结果表明:各药剂对悬铃木方翅网蝽均有控制作用,其效果与药剂种类、施药剂量、施药后时间有关。其中,10倍1.8%阿维菌素乳油+1倍30%乙酰甲胺磷乳油混合液、30%乙酰甲胺磷乳油原药、20倍18%杀虫双水剂进行树干注射效果较好,注药后第7 d虫口减退率均能达到100%,这几种药剂和组合可用于悬铃木方翅网蝽树干注药防治。

This paper studied the control efficiency of Corythucha ciliate by using trunk injection with the five different reagents of 10% imidacloprid WP, 1.8% abamectin oil, 5.7% emamectin benzoate, 30% acephate oil and 18% bisultap aqueous solution. The results showed that all the reagents had efficiency, the effect was related to the types, dosages of reagents and the time after reagents application. The effects of 10 times 1.8% abamectin oil plus 1 time 30% acephate oil, 30% acephate oil, 20 times 18% bisultap aqueous solution are better than the others. After 7 days of applying pesticide application, 100% of the insect were killed. These types of drugs and combinations can be used to control the Corythucha ciliate by trunk injection.
