| Abstract: | The toxicity of nicotine 70% EC, azadirachtin 0.3% EC and the different mixtures of 2 insecticides to Plutella xylostella L. were determined by leaf dripping method in laboratory. The results indicated that azadirachtin 0.125% and nicotine 14.875% had significant synergistic activity. The CTC of mixture 2 was the most significant with the CTC of 264.71. |
