为明确石菖蒲提取物与化学农药混配对褐飞虱的防治作用，研究了石菖蒲提取物与毒死蜱、吡蚜酮和仲丁威3种化学药剂混配网室盆栽条件下的喷雾防治效果。结果表明：石菖蒲提取物与3种化学农药混配，均能达到减少化学农药用量或增加防治效果的作用。25％石菖蒲·毒死蜱乳油1500倍处理褐飞虱的校正死亡率为93．53％，比对照毒死蜱减少了化学农药用量84．38％；25％石菖蒲·吡蚜酮可湿性粉剂1200倍处理褐飞虱的校正死亡率为82．67％，与吡蚜酮对照化学农药用量相同，但防治效果显著提高；25％石菖蒲·仲丁威乳油600倍处理褐飞虱的校正死亡率与对照药剂仲丁威的效果接近，但化学农药用量减少了40．0％。

The control effects of Acorus gramineus extractive mixed with chlorpyrifos , pymetrozine and fenobucarb respectively against Nilaparvata lugens were studied by pot experiment .The results showed that all the 3 kinds of mixtures could reduce the pesticide dosage and enhance the control effects .The corrected mor-tality of 1 500 times 25%extractive-chlorpyrifos EC was 93 .53%, which reduced the chlorpyrifos dosage by 84 .38% compared to the control .The corrected mortality of 1 200 times 25% extractive-pymetrozine WP showed 82 .67%, whose control effect increased significantly compared to the control with the same py-metrozine dosage .The corrected mortality of 600 times 25%extractive-fenobucarb EC was similar to that of control, but its fenobucarb dosage decreased by 40.0%.
