摘要
２５％敌虫灵（甲基异柳磷）水乳剂对萝卜根蛆具有较好的防治效果。根灌试验表明，２５％敌虫灵水乳剂５００倍液防效可达１００％，７５０倍液的防效为９５２％，而１０００倍液的防效与４０％甲基异柳磷乳油１５００倍液的防效大致相同，但可降低成本３１５％。试验结果表明田间应用的最佳稀释浓度为７５０～１０００倍液。
of isofenphos-methyl EW has a good effect against turnip maggots(Hylemya floralis Fallen).Root watering shows that the effectiveness of 25% isofenphos-methyl EW can reach 100% when it is 500 times diluted,and the effectiveness of it can reach 95.2% when it is 750 times diluted.Its effectiveness after 1000 times dilution is the same as that of 40% isofenphos-methyl after 1500 times dilution.But the cost is reduced by 31.5%.The best dilution in the field application should be 750～1000 times.
