经室内毒力测定及田间药效试验研究结果表明：茶皂素对２０％灭多威乳油杀灭菜青虫增效６．３３倍，对２．５％三氟氯氰菊酯乳油杀灭菜缢管蚜增效１４．８３倍，对５％尼索朗乳油杀灭桔全爪螨卵增效６１．８倍，对２０％哒螨灵（ＷＰ）杀灭桔全爪螨成螨增效１８．６７倍。茶皂素与上述化学农药原药复方乳油的田间杀虫效果均稳定保持在９０％以上，与常规对照农药效果经ＤＭＲＴ法显著性分析，在５％水平上无显著差异；而且可以降低化学农药原药有效成分用量５０％～７５％。对于减少化学农药污染环境，开发我国及世界极其丰富的茶皂素资源，具有极显著的社会、生态和经济效益。 The indoor toxicity test and field efficacy test results show that: tea saponin 20% methomyl cream to kill Pieris rapae efficiency of 6.33 times, 2.5% of cyhalothrin EC kill vegetable aphid Synergism of 14.83 times, 5% Nisolong EC to kill orange full-mite egg synergy 61.8 times, 20% of pyridaben (WP) to kill orange mite mite synergistic effect 18.67 Times The pesticidal efficacy of tea saponin and the above chemical pesticide compound EC was stable at above 90%. Significantly different from the conventional control pesticides at the 5% level by DMRT analysis. The chemical pesticides The original active ingredient dosage 50% ~ 75%. It has extremely significant social, ecological and economic benefits for reducing the pollution of chemical pesticides and developing extremely rich tea saponin resources in our country and in the world.
