3种农药防治杨小舟蛾效果比较

Comparative Experiments of 3 Pesticides on Control of Micromelalopha troglodyta

本文采用纱笼法,分析了三种农药(敌杀死、阿维菌素、1.2%烟·参碱乳油)防治杨小舟蛾的效果。结果表明,敌杀死6 000倍和8 000倍灭虫效果最好,在施药48 h后,幼虫死亡率达到了100%;其次为阿维菌素6 000倍液,施药72 h后幼虫死亡率达到了94.48%。从节约成本,保护环境的角度考虑,推荐3种药剂的施用顺序是敌杀死8 000倍液、敌杀死6 000倍液,阿维菌素6 000倍液。

In the paper the screen coop method was adopted in the experiments to study the control effects of 3 pestcides （deltamethrin, abamectin and 1.2% smoke Matrine EC） on Micromelalopha troglodyta. The results showed that the best effects could be achieved with 1：6000 and 1：8000 deltamethri solutions having 100% larva death rate 48 h after application, followed by 1：6000 abamectin solution having 94.48 % death rate 72 h after application. The sequence of 3 recommended pesticides was 1：8000 deltamethrin solution, 1：6000 deltamethrin solution and 1：6000 abamectin solution, taken into account cost savings and environment protection.
