摘要
在大通东峡林区的落叶松纯林中进行乐果和氯氰菊酯两种药剂防治落叶松球蚜的药效对比试验,结果表明,两药剂药效间存在显著差异,以氯氰菊酯的防治效果更好,乐果以1∶500倍液防治效果最好,氯氰菊酯以1∶2000倍液防治效果98%。
Effect contrast test of control Adelages laricis was took place between dimethoate and cypermethrin in pure Larch wood of Adelages laricis Dongxia Forest region Datong. The results showed there was significance between their control effects. The control effect of cypermethrin was better than dimethoate. 1 ： 500 times solution of dimethoate was the best control Adelages laricis. 1 ： 2000 times solution of cypermethrin control effect was 98%.
