Joint-Toxicity and Control Effect of the Mixture of Bt and Chlorbenzuron to the Second and Third Generation Larva of Hyphantria cunea
The Hyphantria cunea's harm has a further exacerbating trend in Jiangsu and the surrounding region.In this study,we found that a mixture of Bt and chlorbenzuron has high toxicity to the second and third generation larva of H.cunea by screening,toxicity test and effect comparison.The toxicity test proved that the synergism was 0.76 and 0.83 times,and the synergized effect was notable.The field test and the aerial control experiment showed that the toxic effect and the lethal rate of the mixture were higher than eigther agent.It is concluded that the mixture of Bt and chlorbenzuron is an effective and safe treatment for controlling H.cunea.
