Abstract

The invention comprises N-methyl-4-chloro-2-nitrophenyl carbamate of formula <FORM:1085698/C2/1> It may be prepared by reacting 4-chloro-2-nitro-phenol with methyl isocyanate in the presence of a basic catalyst, preferably in an organic solvent. The preferred catalysts are organic bases, e.g. triethylamine.ALSO:N - methyl-4-chloro-2-nitrophenyl carbamate of formula <FORM:1085698/A5-A6/1> may be used as a fungicide by itself or in admixture with other plant protection agents. It may be used in conjunction with a solid or liquid diluent or carrier and if desired the composition may contain surface active substances and/or dyestuffs. Suitable solid extenders are, for example, kaolin, talc, silicic acid and clays such as Attaclay; suitable liquid extenders or solvents are, for example, alcohols, ketones, dimethyl formamide, dimethylsulphoxide, water and hydrocarbons; suitable surface active substances are, for example, ligninsulphonic acids and their salts, alkylated benzene sulphonic acids and their salts, sulphonated acid amides and their salts, polyethoxylated amines and alcohols and phenols and their salts; and a suitable dyestuff is, for example, new fuchsine.
