| Abstract: | The toxicity of Xiudan EC, a mixture of endosulfan and Naled, to cotton bollworm (Heliothis armigera Hubner)was tested in green-house. The co-toxicity cofficient (CTC)was 413. 8, indicated a remarkable synergism. The control effects of the combined formulation in field trial were between 89.0 and 93.6% in 1 to 3 days with dilution of 1500 times. The effect of protecting cotton bud was over 88. 0%,and better those of single components respeetively. The toxicacoy esperiment showed that the combined formulation wos safe and more economical. |
