The invention comprises carbamidoximes of formula <FORM:1090357/C2/1> in which X is chlorine, bromine or iodine; R1 is hydrogen, -COR3 or -CONHR3; and R2 and R3 are each a C1-C4 alkyl radical or an aryl radical optionally substituted by halogen, nitro, C1-C4 alkyl and/or C1-C4 alkoxy groups. These compounds may be prepared (a) by reacting an oxime of formula <FORM:1090357/C2/2> with an isocyanate of formula R2NCO, (b) by reacting a carbamidoxime of formula <FORM:1090357/C2/3> with an isocyanate of formula R3NCO or (c) by reacting the carbamidoxime used in (b) with a carboxylic halide of formula R3COHal or a carboxylic acid anhydride of formula R3CO-O-COR3 A large number of examples are given.ALSO:Carbamidoximes of formula <FORM:1090357/A5-A6/1> in which X is chlorine, bromine or iodine; R1 is hydrogen, -COR3 or -CONHR3; and R2 and R3 are each a C1-C4 alkyl group or an aryl radical optionally substituted by halogen, nitro, C1-C4 alkyl and/or C1-C4 alkoxy groups, may be used as herbicides. They may be used in the form of solutions, emulsions, suspensions, powders, pastes and granulates obtained by mixing the compounds with liquid or solid diluents or carries and optionally surface-active agents and/or dispersing agents. The preferred liquid diluents and carriers are water aromatic hydrocarbons, chlorinated aromatic hydrocarbons, paraffins, alcohols, dimethyl formamide and dimethylsulphoxide. Preferred solid diluents are kaolins, clays, talc, chalk, silicic acid and silicates. Suitable emulsifying agents are, e.g. polyoxyethylene esters of fatty acids and polyoxyethylene ethers of fatty alcohols and suitable dispersing agents are, for example, lignin, sulphite waste liquors and cellulose. The active compounds may also be used in mixtures with known active agents, e.g. phenoxy-carboxylic acids, nitrated phenols, urea, uracils, triazines and carbamates.
