Glufosinate-ammonium has significant advantage compared with glyphosate, be embodied as it is following some：1) grass is sweet
Phosphine is glycine class, and to suppress enolpyruvyl shikimene phosphate synthase, protein synthesizes the mechanism of action
It is obstructed；Glufosinate-ammonium is phosphonic acid, and the mechanism of action is that product ammonium is tagged, and suppresses glutamine synthesis；2) it is careless
Sweet phosphine can just take effect after typically taking 7-10 days；Glufosinate-ammonium is generally 3 days (under normal temperature condition)；3)
If decoction drift, glyphosate can kill crop, make crop failure have no harvest；Glufosinate-ammonium only can be in contact site
Medicine spot is produced, plant growth is not had much affect；4) glyphosate fundamentally cannot be used shallow root or root system
Exposed to outer crop such as vegetables, caraway, pepper, grape, pawpaw etc.；Glufosinate-ammonium may be used with nearly institute
There is crop；5) antagonism malignant weed such as eleusine indica, Horseweed Herb etc., glyphosate is invalid, and glufosinate-ammonium has
Effect；6) 20-30 talent can sow transplanting after the general medicine of glyphosate；Glufosinate-ammonium can sow shifting at 1-4 days
