| Abstract: | The toxicity of 5% chlorfluazuron , 4.5% beta-cypemethrin and the different mixtures of 5% chlorfluazuron and 4.5% beta-cypemethrin to Plutella xylostella larvae was determined by leaf immersion method under laboratory condition. The toxicity measurement indicates that the mixtures of 5% chlorfluazuron and 4.5% beta-cypemethrin at the four ratios all had significant synergistic activity and the 39% chlorfluazuron 6% beta-cypermethrin is the highest one, the CTC was 367.22. |
