英文摘要: A new formulation of 5% rotenone emulsion in water( EW) was researched, the virulence for 4% emulsifiable concentrate( EC) and 5% EW of pieris rapae were determined by leaf dipping method. The results indicated that the best solvent was the wintergreen oil, star anise oil( 3∶2, V/V), the emulsifier was silok- 7110 and NP- 400, the other component was tap water. All specifications of5% rotenone EW were up to grade. Bioassay results revealed that the values of LC50 of 4% EC and 5% EW against pieris rapae were315.71, 279.44 mg/kg respectively, the virulence EC less than EW.
中文摘要: 通过试验研究5%鱼藤酮水乳剂的制备方法,采用浸叶法测定4%鱼藤酮EC和5%鱼藤酮EW对菜青虫的室内毒力。结果表明,以冬青油和八角茴油(3∶2,V/V)为溶剂、Silok-7110和NP-400为乳化剂、自来水为介质配制成的鱼藤酮EW,各项理化指标均合格;对菜青虫的毒力,EC的致死中浓度(LC50)为315.71 mg/kg,EW的LC50为279.44 mg/kg,EW的毒力较EC稍高。
