摘要
用微量点滴法测定了倍硫磷与氰戊菊酯混用对大豆食心虫Leguminivoraglycinivorella (Matsumura)的毒力 .结果表明 ,倍硫磷与氰戊菊酯以 15∶1的质量比混合时 ,增效作用最为显著 .按此配比制成的质量分数为 30 %倍·氰乳油 ,喷施 4 5 0g·hm-2 。
The joint toxicities of mixed insecticides of fenthion and fenvalerate against soybean pod borer Leguminivora glycinivorella (Matsumura) were determined in laboratory with topical application. The results showed that the synergistic effect was the most remarkable when the ratio of fenthion to fenvalerate was 15∶1. The mixtures of fenthion and fenvalerate prepared by this ratio showed higher efficacy than fenthion or fenvalerate alone did against L. glycinivorella in the field.
