Abstract

The effects of botanical pesticides were evaluated against cabbage caterpillar(Pieris rapae L) in field trail.Compared with 8000IU/mg BT D,0.9% abamactin EC and 4.5% beta-cypermethrin,botanical pesticides1.6% LDS AS 1000 times dilution,0.2%KPS EC 1000 times dilution,10% nicotin EC 1000 times dilution and 0.5% toosendanin EC times dilution can give an fine effect,with the control effect of 71.72% to 100% after to 7 days of spraying.They are the harmless pesticides of control cabbage caterpillar(Pieris rapae L).
