摘　　要：本试验比较了不同浓度氯虫苯甲酰胺水分散粒剂对桃小食心虫的防治效果。结果表明:试验药剂35%氯虫苯甲酰胺水分散粒剂在水中分散性良好,700倍用药量(有效成分量为41.2 g/hm^2)防治桃小食心虫的速效性和持效性均良好,14 d后防效达到最大值,为99.1%。试验证明,氯虫苯甲酰胺水分散粒剂可用来防治果树桃小食心虫。In this experiment,the control effect of chlorantraniliprole water dispersible granule with different concentration on Carposina sasakii Matsumurawas compared.The results showed that 35%chlorantraniliprole water dispersible granule had good dispersibility in water.Under 700 times of dosage(the amount of effective components wa 41.2 g/hm^2),the control effect was good.After 14 days,the maximum control effect was 99.1%,which could be used to control Carposina sasakii Matsumura.
