【Abstract】 Field tests with 1 % avermectin EC to control Aphispomi DeGeer,Myzus persicae (Sulzer) and Brevicoryne brassica(L. ) were conducted in 1996 and 1997.The results showed that avermectin was highly effective in controlling these three species of aphides. The control effects were all over 90 % after seven days of using this pesticide with 1000 and 2000 times diluents. The pesticidal action lasted for 14 days, and no side- effect was found.更多还原
