摘　　要：【目的】研制高效广谱除草剂21%乙羧·草铵膦微乳剂配方,对其理化性能进行检测,并将其用于防除非耕地杂草。【方法】采用优化组合法对不同表面活性剂进行筛选试验,确定21%乙羧·草铵膦微乳剂最优配方。通过田间药效试验研究21%乙羧·草铵膦微乳剂对非耕地杂草的防除效果。【结果】最优配方(质量分数)为:20%(折百)草铵膦,1%乙羧氟草醚,7%环己酮,10%正丁醇,20%乳化剂(OA-TAPO∶烷基糖苷∶甜菜碱=3∶2∶1),水补足100%。田间试验结果表明,21%乙羧·草铵膦微乳剂270~540 mL/hm^(2)对非耕地杂草有明显的防除效果,茎叶喷雾药后5 d对禾本科杂草、阔叶杂草的覆盖度防效可达80.41%~83.47%、84.44%~88.13%,药后10 d对禾本科杂草、阔叶杂草的覆盖度防效可达92.69%~94.55%、95.61%~96.72%,药后30 d对禾本科杂草、阔叶杂草的覆盖度防效可达93.64%~96.04%、97.59%~98.45%,鲜质量防效可达93.65%~96.09%、97.37%~98.51%。【结论】草铵膦与乙羧氟草醚复配可拓宽除草谱;21%乙羧·草铵膦微乳剂可以有效防除非耕地杂草,速效性与持效性优于市售20%草铵膦可溶液剂、10%乙羧氟草醚乳油。【Objective】The high effective and broad-spectrum herbicide,21%Fluoroglycofen-glufosinate ME,was developed and applied in the control of non-arable weeds,and its physical and chemical properties were determined.【Method】The optimal combination method was used to screen out different surfactants to determine the optimal formula.Control effect of 21%Fluoroglycofen-glufosinate ME against non-arable weeds was studied by field tests.【Result】The optimal formula of 21%Fluoroglycofen-glufosinate ME(mass fraction)was:20%Glufosinate-ammonium,1%Fluoroglycofen-ethyl,7%cyclohexanone,10%n-butanol,20%emulsifier(OA-TAPO∶alkyl glucoside∶betaine=3∶2∶1),and water to made up for 100%.Field test results showed that,21%Fluoroglycofen-glufosinate ME with dosages of 270-540 mL/hm^(2) had obvious control effect on non-arable weeds.The coverage control effects against gramineous weeds were 80.41%-83.47%(treatment after 5 d),92.69%-94.55%(treatment after 10 d),93.64%-96.04%(treatment after 30 d)and those against broadleaf weeds were 84.44%-88.13%(treatment after 5 d),95.61%-96.72%(treatment after 10 d),97.59%-98.45%(treatment after 30 d),respectively.The relative fresh weight control effect could reach 93.65%-96.09%and 97.37%-98.51%,respectively.【Conclusion】21%Fluoroglycofen-glufosinate ME can broaden the herbicide spectrum and effectively control non-arable weeds.It shows better performance on quick-acting property and continuous effects than those of 20%glufosinate-ammonium SL and 10%fluoroglycofen-ethyl EC.
