COMPOSITIONS AND METHODS TO IMPROVE COMPATIBILITY OF SOLUBLE HARBICIDES SOLUBLE IN WATER Russian patent published in 2017 - IPC A01N57/20 A01N37/40 A01P13/00 

FIELD: chemistry.

SUBSTANCE: method for improving the compatibility of an aqueous solution of a herbicide comprising at least one of the following salts: a water soluble salt of aryloxyalkanecarboxylic acid, a water soluble pyridyloxyalkanecarboxylic acid salt and a water soluble glyphosate salt, and optionally ≤16% of one or more fertilizers, includes Adding to the aqueous solution of the herbicide one or more polymer crystallization inhibitors I , in which A means , where R₁, R₂ and R₃ Independently are H, CH_3, COOH or CH₂COOH, L is a bridging group represented by -C (==O)-O-, -C(==O)-N-, -CH₂-, -O-, -O-C(==O)- or a direct link, and R_hy is hydrophobic and includes a linear or branched alkyl, cycloalkyl, aryl, alkylaryl or alkoxylated derivative thereof; B is obtained by polymerizing a monomer of ethylenically unsaturated carboxylic acid and/or its salts; and C is optional and obtained by polymerizing a monomer of ethylenically unsaturated sulfonic acid or a phosphonic acid monomer and/or salts thereof.

EFFECT: invention enables realisation of the mentioned purpose.
