| 【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% 环已酮，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/hm2 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% Fluoroglycofenethyl, 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/ hm2
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. |
