16 16 26The 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 C Calkyl 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 C Calkyl 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 (C C 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).
