| Abstract: | The effects of three plant original insecticides were evaluated against Pieris rapae L. in the field. The results showed that 0.1% rhodojaponin EC and 0.3% azadirachtin EC provided with 98.13%-100% and 82.43%-90.69% control percantage after 3-7 days and 10 days with the dilution times of 1 000-2 000 respectively. It was similar to the effect of 4.5% bata-cypermethrin EC, and 2.5% rotenone EC also provided a satisfactory control effect under the concentration of 500-1 000 dilution times. |
