氯氰菊酯与渗透剂混配防治长足大竹象试验

Study on Cypermethrin Mixing with Penetrating Agent against Cyrtotrachelus buqueti Guer

采用氯氰菊酯和以氯氰菊酯为主体添加百威3号高渗增效剂对慈竹长足大竹象进行了防治试验,以竹笋成竹率评价防治效果。结果表明,氯氰菊酯具有较好的防治效果,使慈竹竹笋的成竹率从50.2%提高到74.1%,估算竹材增产47.6%;百威3号高渗增效剂能增强农药渗透能力,从而提高防治效果,使竹笋成竹率从50.2%提高到84.7%,估算竹材增产68.7%。

The experiment in the control of the insect （ Cyrtotrachelus buqueti Guer ） with cypermethrin and a mixture of cypermethrin and penetrating agent was carried out. The controlling effect were evaluated according to bamboo shoot survival rate. The results showed that cypermethrin had quite efficient controlling effect on Cyrtotrachelus buqueti Guer. The percentage of bamboo shoot developed into normal bamboo was increased from 50.2% to 74.1% and the production of bamboo was increased by 47.6%. The mixture of cypermethrin and penetrating agent had more efficient controlling effect on Cyrtotrachelus buqueti Guer than cypermethrin. The percentage of bamboo shoot developed into normal bamboo was increased from 50.2% to 84.7% and the production of bambpp was increased by 68.7%.
