摘要
试验结果表明，７０％敌溴菊酯乳油２０００、３０００、４０００倍液防治棉叶螨，１０天后的防效为９０．２～９５．２％，显著高于２０％双甲脒１５００倍液和２．５％溴氰菊酯３０００倍液７０％的防效，略低于５０％克螨特３０００倍、１５％哒螨灵３０００倍、２０％三氯杀螨醇１５００倍液的防效，但差异不显著。建议生产中敌溴菊酯的使用浓度以３０００倍为宜。
he test results show that 70% Di-Xiu EC(a mixture of trichlorfen and deltamethrin)is effective to control cotton mite (Anychus latus C. et F. ). More than 90% of the pests were controled after 10 days by using 2000, 3000 and 4000 times diluents of 70% Di-Xiu EC. The effects are higher than those of 20% amitraz EC 1500 times diluent and 2.5% deltamethrin EC 3000 times diluent , and is similar to those of 50% propargite EC 3000 times and 15% pyridaben EC 3000 times diluents. It is suitable to use 3000 times diluent in the field.
