Beschreibung
Zusammenfassung:	The invention relates to a manufacturing method of a herbicide, the technical proposal of which is to oxidize PMIDA to get mixed glyphosate solution, separate 20-80 percent of mother liquor after keeping stationary with reaction pressure controlled between 0.04MPa and 0.095MPa and reaction temperature controlled between 60 DEG C and 95 DEG C, take partial water from heat reaction to add the agenttaking 5-30 percent weight of the mixed glyphosate solution and padding taking 2-15 percent weight of the mixed glyphosate solution into the mixed glyphosate solution; after even stirring, spraying and granulation are to get granules of the glyphosate. The invention is characterized by scientific process, reasonable materials use, simple operation, low production costs and high product yields.
