Aqueous solution with glyphosate.dicamba and preparation method of aqueous solution

The invention provides an aqueous solution with glyphosate.dicamba and a preparation method of the aqueous solution. The aqueous solution is prepared through a process that an active compound of glyphosate is reacted with dimethylamine, the loss of dimethylamine is reduced to 2-3% from current 20-30%, the cost is greatly lowered, tail gas emission is reduced, and atmospheric pollution is reduced. The prepared aqueous solution has various excellent indexes. 本发明提供种包含草甘膦·麦草畏的水剂及其制备方法；本发明的水剂由草甘膦原药与二甲胺反应工艺，使二甲胺损失量由目前的20-30％降低到2％-3％，大大降低成本，减少尾气排放，降低大气污染。制备得到的水剂各项指标优异。
