乙羧·草铵膦微乳剂的研制及对非耕地杂草防效

摘要

通过表面活性剂的筛选,制备出20%乙羧·草铵膦微乳剂,并将其应用于防除非耕地杂草.结果表明:利用电荷屏蔽等界面手段制备的20%乙羧·草铵膦微乳剂性能良好,其中SKCL-7和SKCL-19(质量比2︰1)复配作为表面活性剂,SK-21为助表面活性剂,表面活性剂总用量为35%.20%乙羧·草铵膦微乳剂速效性与持效性优于18%草铵膦水剂、10%乙羧氟草醚乳油和20%乙羧·草铵膦可分散油悬浮剂.%Fluoroglycofen-ethyl + glufosinate-ammonium 20% ME was prepared by surfactants screening test, and the formulation applied to control weeds in non-cultivated land. The results showed that the ME had excellent properties. SKCL-7 and SKCL-19 with the mass ratio of 2:1 worked as the surfactants in the ME, SK-21 was selected as cosurfactant, and the total amount of the surfactants was 35%. Fluoroglycofen-ethyl + glufosinate-ammonium 20% ME exhibited better quick-acting and persistence efficacy, comparing with glufosinate-ammonium 18% AS, fluoroglycofen-ethyl 10% EC and fluoroglycofen-ethyl + glufosinate-ammonium 20% OD.
