1. A flowable herbicidal composition in the form of an aqueous suspension which consists of at least one solid disperse phase and a continuous aqueous phase, and which contains as active component at least one herbicidally active urea derivative, which composition comprises : 45 - 66% by weight of one or more urea derivatives of the formula I see diagramm : EP0163598,P12,F1 in which R1 is benzothiazol-2-yl, 5-trifluoromethyl-1,3,4-thiadiazol-2-yl or a phenyl group of the formula see diagramm : EP0163598,P12,F2 in which R5 is hydrogen, chlorine, bromine or C1 -C4 -alkyl, R6 is hydrogen, chlorine, trifluoromethyl or C1 -C4 -alkylaminocarbonyloxy, wherein however R5 and R6 cannot simultaneously be hydrogen, R2 is hydrogen or, when R1 is benzothiazol-2-yl or 5-trifluoromethyl-1,3,4-thiadiazol-2-yl, R2 is methyl ; R3 is methyl, and R4 is methyl or methoxy, or, when R1 is benzothiazol-2-yl or 5-trifluoromethyl-1,3,4-thiadiazol-2-yl, R4 is hydrogen, or of a mixture of one or more urea derivatives of the formula I and a further solid herbicidal active substance difficultly soluble in water ; 2 - 10% by weight of at least one mono- or di-(phenolpolyglycol ether)-phosphoric acid ester, or of a salt thereof, of the formula III see diagramm : EP0163598,P12,F3 in which R7 is a radical of the formula see diagramm : EP0163598,P12,F4 R8 has the same meaning as R7 or is hydrogen, and M is a proton, or a sodium, potassium, diethylammonium, triethylammonium, diethanolammonium or triethanolammonium cation, R9 being hydrogen, C3 -C10 -alkyl or styryl, m an integer from 1 - 4, and n an integer from 4 - 40 ; 0.1 - 5% by weight of at least one polyglycol ether of the formula III R10 -O-(-CH2 -CH2 -O-)-p -H wherein R10 is C12 -C18 -alkyl, C12 -C22 -alkanoyl, C12 -C22 -alkenoyl, C12 -C22 -alkadienonyl, C12 -C22 -alkatrienonyl, or phenyl mono- to trisubstituted by C3 -C10 -alkyl, C5 -C8 -cycloalkyl or styryl, and p is an integer from 1 - 6 ; 0 - 3% by weight of an auxiliary dispersing agent ; 0 - 10% by weight of an anti-freezing agent ; and 20 - 40% by weight of water. |
