LIQUID AGROCHEMICAL COMPOSITIONS COMPRISING A POLYMERIC THICKENER AND AN ALCOHOL-CONTAINING SOLVENT SYSTEM, AND LIQUID HERBICIDAL COMPOSITIONS HAVING AN ALCOHOL-CONTAINING SOLVENT SYSTEM

The invention provides a liquid agrochemical composition, preferably in the form of an emulsifiable concentrate (EC), comprising a mixture of: one or more agrochemically active ingredients (in particular comprising one or more herbicides); a C1-C6 alkyl methacrylate polymer (preferably an isobutyl methacrylate polymer); and a solvent system comprising: (c1) an alcohol solvent comprising hexylene glycol (2-methyl-2,4-pentanediol), benzyl alcohol, diacetone alcohol (2-methyl-4-oxo-pentane-2-ol), isobutanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, 2-ethyl-hexanol, cyclohexanol, dipropylene glycol, diethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, ethylene glycol, or a mixture of two or more of these alcohols(preferably hexylene glycol); and (c2) aheavy aromatic hydrocarbon solvent. The C1-C6 alkyl methacrylate polymer generally acts as a thickener which is suitable for the defined solvent system, and which is for increasing the viscosity of the composition. The invention also provides a liquidherbicidal composition, preferably in the form of an emulsifiable concentrate, comprising a mixture of: (a) one or more agrochemically active ingredients comprising one or more herbicides, wherein the one or more herbicides comprise: (a1) pinoxaden; (a2) florasulam or a salt; (a2a) metosulamor a salt;(a2b) diclosulam or a salt; (a2c) cloransulam-methyl; or (a3) clodinafop-propargyl; or a combination of either (a2) florasulam or (a2a) metosulamor a salt of one of these with (a1) pinoxaden and/or (a3) clodinafop-propargyl; and (c)a solvent system comprising: (c3) a (C2-C6-alkylene) carbonate such as 1,2-propylene carbonate; and (c1a) an alcohol solvent comprising hexylene glycol, benzyl alcohol, diacetone alcohol, isobutanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, 2-ethyl-hexanol, cyclohexanol, dipropylene glycol, diethylene glycol monomethyl ether, dipropylene glycol monomethyl ether, or a mixture of two or more of these alcohols(preferably benzyl alcohol).
