摘要
为有效防治落叶松球蚜对红皮云杉的危害,利用20%吡虫啉可溶性粉剂,以有效成分600 g·hm^(-2)、750 g·hm^(-2)、900 g·hm^(-2)、1 200 g·hm^(-2)剂量地下实施,其防治效果比较明显,在61. 11%~94. 44%,红皮云杉苗木生长安全。建议使用吡虫啉有效成分600 g·hm^(-2)用于生产防治。
In order to effectively prevent the damage of Adelges laricis to Picea koraiensis,20%imidacloprid soluble powder was used,with active ingredients 600 g·hm-2,750 g·hm-2,900 g·hm-2,1 200 g·hm-2 dose were applied underground.The control effect was obvious,61.11%~94.44%.The growth of Picea koraiensis seedlings were safe.It was recommended to use imidacloprid active ingredient 600 g·hm-2 for production control.
