COMPOSITIONS AND METHODS OF IMPROVING COMPATIBILITY OF WATER-SOLUBLE PESTICIDAL SALTS AND CONCENTRATED FERTILISER Russian patent published in 2017 - IPC A01N25/02 A01N39/04 A01N37/40 A01P13/00 C05G3/02 

FIELD: agriculture.

SUBSTANCE: to improve the compatibility of an aqueous herbicidal solution containing at least one water-soluble salt of a herbicidally active ingredient and a concentrated fertiliser, wherein said concentrated fertiliser comprises >16 wt % of one or more fertilisers, one or more polymer crystallization inhibitors of the structure I

are added to the aqueous herbicidal solution, where A is represented by

,

where R₁, R₂ and R₃ are represented independently by H, CH₃, COOH, or CH₂COOH, L is a linking group containing -C(=O)-O-, -C(=O)-N-, -CH₂-, -O-, -O-C(=O)-, urethane, urea or a direct bond, and wherein R_hy is represented by a hydrophobic fragment and includes a linear or branched alkyl, cycloalkyl, aryl, alkaryl, or their alcoxylized derivative, B is obtained by polymerization of a monomer of ethylenediamine carboxylic acids and/or their salts; and C is optional and is obtained by polymerization of a monomer of ethylenediamine sulfonic acids or phosphonic acids and/or their salts, and x is represented by the molar percentage of A and ranges from about 5 to 80%, z is represented by the molar % of C and ranges from approximately 0 to 25%, and represents the molar % of B, which ranges from about 1 to 95 of molar %.

EFFECT: reducing crystallization of active ingredients.
