    Abstract: The invention concerns sulfonyl urea derivatives of formula (I), wherein R1 stands for optionally substituted alkyl or phenyl; alkenyl or propargyl; alkylamino or dialkylamino; R2 stands for hydrogen, halogen, optionally halogen-substituted methyl, methoxy or ethoxy, an alklylsulfonyl group, nitro or cyano; R3 stand s for difluoromethoxy, trifluoromethoxy, brom- odifluoromethoxy, chlorodifluoromethoxy or fluorine; R4 stands for halogen, optionally halogen-substituted methyl, ethyl, methoxy or ethoxy or the methylamino or dimethylamino group; R5 stands for hydrogen, alkyl, alkenyl or an alkinyl; Z stands for CH or N, provided that a) if R3 stands for the difluoromethoxy group, R1 does not stand for a di(alkyl)amino group, R2 does not stand for an alkylsulfonyl group, and R4 does not stand f or a methyl or methoxy group, b) if R3 stands for a fluorine atom and Z stands for nitrogen, R4 does not stand for an alkylamino group. The invention also concerns their salts. The sulfonyl urea derivatives can be used as herbicides.

    Abstract: A mixture consisting essentially of: a) one or more dicarboxylic acid esters of the formula I ROOC-A-COOR (I) in which the radicals R independently of one another are alkyl groups having 1 to 20 carbon atoms and A is alkylene having 1 to 20 carbon atoms, alkenylene or alkynylene each having 2 to 20 carbon atoms, cycloalkylidene or cycloalkenylidene each having 5 or 6 carbon atoms or phenylene and b) the product (II) of the reaction of a triglyceride based on carboxylic acids having 2 to 30 carbon atoms and ethylene oxide and/or propylene oxide in the presence of a base, which is useful for the production of crop protection compositions, for herbicidal crop protection compositions, and for controlling undesired plant growth, and spray mixtures comprising the compositions.
