20%丁硫克百威乳油防治苹果蚜虫田间药效试验

Efficiency of Carbosulfan 20 EC against Aphis pomi

１９９５～１９９６年在山西太原进行了２０％丁硫克百威乳油防治苹果蚜虫田间小区药效试验，结果表明，在苹果蚜虫发生期，用丁硫克百威１０００～３０００倍液喷雾防治，１～８天的防效可达９９．７％～１００％，７～１０天的防效仍维持在８５％以上。其防效与对照农药４０％氧乐果１０００倍液的防效相等，持效期为１０天。

Field trials was carried out from 1995 to 1996 in Taiyuan of Shanxi Province for efficiency test of carbosulfan 20 EC on control of Aphid pomi.The result demonstrated that three dosages of carbosulfan had a good effect to control the aphis on apple tree.The control efficiency was about 100% from 1 to 3 days after treatment and the persistent effect kept about 10 days,which was similar to that of conventioal insecticide,40 EC omethoate.
