PESTICIDE SUSPENSION CONCENTRATE AND FERTILIZER COMPOSITION WITH IT Russian patent published in 2022 - IPC A01N25/04 C07F9/09 C05G1/02 

FIELD: agriculture.

SUBSTANCE: pesticide suspension concentrate contains 1-15 wt.% of composite ester of phosphoric acid, having the general formula

where X is selected from a group consisting of H, cation, and R²O(AO)_z2; Y is selected from a group consisting of H, cation, and R³O(AO)_z3; R¹, R², and R³ are independently linear or branched alkyl groups having 4-11 carbon atoms; each AO is independently an alkylene oxy group; and z1, z2, and z3 are independently a number from 1 to 4, 4-50 wt.% of water-insoluble solid pesticide, and 35-95 wt.% of water. The pesticide suspension concentrate additionally contains a fertilizer, such as 10-34-0 fertilizer. A method for the production of the pesticide suspension concentrate includes obtainment of composite ester of phosphoric acid by interaction of alkoxylated alcohol with one or more of polyphosphoric acid and phosphorus pentoxide, combination of composite ester of phosphoric acid with water-insoluble solid pesticide and water to obtain a suspension concentrate.

EFFECT: proposed pesticide suspension concentrate is stable during both storage and use, while it is suitable for use in a combination with strong electrolytes, such as 10-34-0 fertilizer, providing obtainment of a stable mixture for spraying.
