Preparation method: add crude glufosinate-ammonium into acidic aqueous solution,
heat to form a dissolution equilibrium, then cool down to precipitate solid,

Filter, and the filtrate is post-treated to obtain refined L-glufosinate-ammonium from agrofarm chemical;

The content of L-glufosinate-ammonium in the crude product of glufosinate-ammonium is greater than 52%;

The pH value of the acidic aqueous solution is 1.2-4.0.

Application: L-glufosinate ammonium is updated products than glufosinate ammonium, can kill weed with faster
speed, it is treated as Replacement of Paraquate.
