摘　　要：本文初步研究了丰威防治棉花三代棉铃虫的田间药效。结果表明１０％丰威微乳剂对棉铃虫作用迅速，防治效果显著，田间施药用６７５～９００ｍｌ／ｈａ，对棉铃虫在药后１ｄ、３ｄ、７ｄ的防效和保蕾效果均明显优于对照药剂．使用后棉花生长且无任何不良影响．The field effect of the Fengwei 10% EW on controlling bollworms was primarily studied. The resultshowed that the Fengwei 10% EW could rapidly killed bollworms with high effect. Under the condition ofapplying 675￣900 ha, the effects of controlling bollworms and protecting buds were obviously higher than thoseby using control pesticides on the first, third and seventh day after spraying without any by-side effects on thecotton growth.
