AGROCHEMICAL FORMULATION

摘要

An aqueous agrochemical concentrate formulation comprises a) an agrochemical electrolyte such as salts of glyphosate, fomesafen, glufosinate, paraquat or bentazone, b) an alkoxylated adjuvant, c) an alkylglycoside and d) a co-surfactant which interacts with the alkylglycoside to form a structured aqueous system. Preferred co-surfactants are: (i) a linear or branched chain aliphatic or aromatic alcohol, (ii) an alcohol or ester or alkyl phenol alkoxylate having a degree of alkoxylation lower than that of the alkoxylated adjuvant present in the formulation as component (b), (iii) a glyceryl alkyl or alkenyl ester and (iv) a sorbitan alkyl or alkenyl ester. The alkyl glycoside and the co-surfactant interact to provide a structured aqueous system such that if the critical concentrations are exceeded and one or more components (normally the alkoxylated adjuvant) can no longer be maintained in a single-phase aqueous system, the second phase forms a stable dispersion (normally a liquid phase dispersion) which is supported within the structured aqueous system.
