Field Trial of 25% Mxture of Cypermethrin and Phoxim Microemulsion against Cotton Bollworm and Cabbage Butterfly |
| |
Abstract: | The experiment was carried out for measuring effect of 25% mixture of cypermethrin and phoxim microemulsion against cotton bollworm ( Heliothis armigera H) and cabbage butterfly ( Pieris rapae )in field trials. The result showed that the mixture of cypermethrin and phoxim had a good effect to control the two pests. The control effect of the mixture with 1 000~1 500 times dilution to cotton bollworm and the effect on protecting the cotton buds and bolls were about 79% and 74% during 5 day after spraying treatment, and the effect to cabbage butterfly was 94%, which was similar to that by using alphacypermethrin 5 EC or cypermethrin 10 EC and better than that by applying phoxim 40 EC. |
