摘　　要：为探究草莓定植前吡虫啉蘸根处理对蚜虫的防治效果,分别在江苏句容和东海进行不同剂量吡虫啉蘸根处理防治草莓蚜虫的田间试验。结果表明:10%吡虫啉可湿性粉剂50倍液、250倍液、500倍液蘸根处理,可以有效防治蚜虫,且持效期均在90 d以上;10%吡虫啉可湿性粉剂50倍液、250倍液蘸根处理易产生药害,影响草莓生长;10%吡虫啉可湿性粉剂500倍液、800倍液蘸根处理对草莓生长无影响。To study the control effects of imidacloprid 10% WP aganist strawberry aphid by root dipping method, field experiments were conducted in Jurong and Donghai of Jiangsu Province. The results showed that the treatments of root dipping method could control aphid effectively, with the dose of 50, 250 and 500 times of imidacloprid 10% WP. But at the doses of 50 and 250 times, imidacloprid had bad effects on the growth of strawberry. At the doses of 500 and 800 times,imidacloprid was safe to strawberry growth.
