摘　　要：１９９３、１９９４年用４０％丙溴磷乳油进行了防治棉铃虫药效试验，两年的试验结果表明，亩用该药６０、８０、１００毫升，在药后７天均达到了８０％以上的防效，亩施１００毫升，防效均达到９３．７％以上，明显高于２．５％三氟氯氰菊酯乳油亩施３０毫升的防效７７．０％。该药是一种防治抗性棉铃虫的优良杀虫剂，建议棉田用量为亩施８０～１００毫升为宜。A test of control cotton bollworm with 40% pro-fenofos EC was performed in 1993 and 1994.The resultsshowed that the control effect of each of tests was over 80%after 7 days of using the insecticide with 900ml/ha and1200ml/ha while the effect was over 93.7%with 1500ml/haof the insecticide.
