51%草甘膦·绿草定酯可分散油悬浮剂的配方研制

Preparation of 51% Glyphosate+Triclopyr-butotyl OD

采用湿法研磨工艺,将草甘膦和绿草定酯复配制备成可分散油悬浮剂。通过对乳化剂、分散剂、增稠剂、分散介质进行的筛选试验,确定其最优OD配方为:30%草甘膦、21%绿草定酯、18%乳化剂OF-803G、2%分散剂OF-3498D、1%有机土SK-04、1%白炭黑AEROSIL■R 974、油酸甲酯0295补齐到100%。结果表明,所制制剂分散性优,储存稳定性良好,各指标均符合可分散油悬浮剂的相关标准要求,且对柑橘园马唐、婆婆纳、香附子和鸭跖草等杂草有很好的防治效果。

Glyphosate+Triclopyr-butotyl OD was prepared by wet grinding process.By screening emulsifiers,dispersants,thickeners and disperse mediums,the optimum formula was determined as follows:30%glyphosate,21%triclopyr-butotyl,18%OF-803G,2%OF-3498D,1%SK-04,1%AEROSIL■R 974 methyl oleate making up to 100%.The formulation had good dispersibility and storage stability.All specifications conformed to the requirements of OD.The control effects of Glyphosate+Triclopyr-butotyl 51%OD on weeds in citrus orchard,such as digitaria sanguinalis,veronica didyma tenole,Cyperus rotundus L.and dayflower.
