FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. Herbicide composition with increased solubility in presence of cations of ammonium, sodium, potassium, calcium, magnesium and multivalent cations contains at least one amine herbicide salt of phenoacid class and solubility-improving preparation in amount, effective for preventing formation of insoluble salts of said herbicide of phenoxyacid class. Said solubility-improving preparation contains at least one surface active substance, selected from alcoxylated quaternary amine, alkylated quaternary amine, amidoamine, alkoxylate of product of interaction of fatty acid and polyamines, ethoxylate of product of interaction of fatty acid and triethylamine, tristyrylphenol ethoxylate, EO-PO block or statistical copolymer, alkyl olefin sulfonate, alkylbenzene sulfonate amine salt, castor oil alcoxylate, inorganic base or their combinations, on condition that when glyphosate is present, inorganic base is excluded. Said herbicide of phenoxy acid class represents herbicide of class of phenoxyacetic acids, herbicide of class of phenoxybutyric acids, herbicide of class of phenoxypropionic acids, herbicide of class of aryloxyphenoxypropionic acids, 4-CPA, 2,4-D, 3,4-DA, MCPA, MCPA-thioethyl, 4-CPB, 2,4-DB, 3,4-DB, MCPB, cloprop, 4-CPP, dicloroprop, dicloporpop-P, 3,4-DP, phenoprop, mecoprop, mecoprop-P, clorazifop, clodinafop, clofop, cihalofop, diclofop, phenoxaprop, phenoxaprop-P, fentiaprop, fluazifop, haloxyfop, haloxyfop-P, isoxapyrifop, metamifop, propaquizafop, quizalofop, quizalofop-P, trifop and their combinations. Ratio of amine salt of herbicide of phenoxyacid class to solubility-improving preparation constitutes from 10:1 to 1:1.5. Solubility-improving preparation and amine salt of herbicide are mixed.
EFFECT: invention makes it possible to improve composition stability.
