【摘要】 利用室内浸渍法测定了双甲脒与溴氰菊酯、氰戊菊酯混用对麦长管蚜 (MacrosiphumavenaeF )的增效作用。溴氰菊酯、氰戊菊酯与双甲脒均以 2∶1比例混合时 ,增效作用最为显著 ;但当溴氰菊酯与双甲脒以 15∶1混用、氰戊菊酯与双甲脒以 1∶10混用时会产生严重的拮抗作用 ,同各单剂分别使用时相比效果明显降低。更多还原

【Abstract】 The synergistic effects of the mixing deltamethrin or fenvalerate with amitraz were determined by laboratory immersion method The results showed the synergistic effect was the most remarkable when set in the ratio of 2∶1,but when deltamethrin or fenvalerate was mixed with amitraz in 15∶1?1∶10 respectively, the antigonistic effect would be expressed更多还原
