Stable liquid composition for treatment of ferric chlorosis contains ferric ethylene diamine hydroxy phenyl acetic acid salt, dispersing agent, and polymeric alkylene oxide

摘要

Stable liquid composition contains: (A) at least one sodium or potassium salt of EDDHA Fe(III) (ethylene diamine-N,N'-bis (o- or p-hydroxy phenyl acetic) acid), and/or EDDHMA Fe(III) (ethylene diamine-N,N'-bis (o- or p-hydroxy-4- or -5-methyl phenyl acetic) acid); (B) 1-5% dispersing agent and (C) 15-35% polymeric alkylene oxide. Stable liquid composition contains: (A) at least one sodium or potassium salt of EDDHA Fe(III) (ethylene diamine-N,N'-bis (o- or p-hydroxy phenyl acetic) acid), and/or EDDHMA Fe(III) (ethylene diamine-N,N'-bis (o- or p-hydroxy-4- or -5-methyl phenyl acetic) acid); (B) 1-5% dispersing agent and (C) 15-35% polymeric alkylene oxide selected from polyethylene glycols of molecular weight 200-400, polypropylene glycols of molecular weight 400-600, or their derivatives.
