PESTICIDE SUSPENSION CONCENTRATE AND FERTILIZER COMPOSITION THEREWITH

A suspension concentrate includes a phosphate ester having the general formula: where X is selected from the group consisting of H, a cation and R2O(AO)Z2; Y is selected from the group consisting of H, a cation and R3O(AO)Z3; R1, R2 and R3 are linear or branched alkyl groups having from 4 to 1 1 carbon atoms; AO is an alkoxy group; and z1, z2 and z3 are numbers from 1 to 4. The suspension concentrate further includes a water-insoluble solid pesticide and water. A method includes preparing a phosphate ester by reacting an alcohol alkoxylate with one or more of polyphosphoric acid and phosphorous pentoxide. The alcohol alkoxylate includes a base alcohol having from 4 to 1 1 carbon atoms and also includes, on average, from 1 to 4 alkoxy groups. The method further includes combining the phosphate ester with a water-insoluble solid pesticide and water to form a suspension concentrate. 本发明涉及一种悬浮浓缩物，其包含：磷酸酯，其具有如下通式，其中X选自H、阳离子和R2O(AO)z2-；Y选自H-、阳离子和R3O(AO)z3-；R1、R2和R3独立地为具有4-11个碳原子的线性或支化烷基，AO为烷氧基，z1、z2和z3为1-4的数。所述悬浮浓缩
