Abstract

N-Methyl-N-(sulphonic acid amide-N'-sulphenyl)-carbamic acid esters of the formula ##STR1## in which R.sup.1 is dialkylamino with 1 to 4 carbon atoms in each alkyl radical, phenyl or phenyl carrying at least one halogen, alkyl with 1 to 4 carbon atoms, nitro or trihalogenomethyl substituent, PA1 R.sup.2 is alkyl with 2 to 8 carbon atoms, cycloalkyl, phenyl or cycloalkyl or phenyl carrying at least one halogen, alkyl with 1 to 4 carbon atoms, nitro or trifluoromethyl substituent, and PA1 R.sup.3 is phenyl, naphthyl, benzodioxolanyl, dihydrobenzofuranyl or indanyl; phenyl, naphthyl, benzodioxolanyl, dihydrobenzofuranyl or indanyl substituted at least once by trihalogenomethyl, halogen, nitro, cyano, cycloalkyl, formamidino, dioxanyl or dioxolanyl, or by alkyl, alkenyl, alkynyl, alkoxy, alkenoxy, alkynoxy, alkylmercapto, alkenylmercapto, alkynylmercapto or dialkylamino, each with up to 4 carbon atoms per aliphatic moiety, or an oxime radical of the formula ##STR2## R.sup.4 and R.sup.5 each independently is cyano or alkyl, alkoxy, alkylthio, alkoxycarbonyl, dialkylcarbamoyl or dialkoxyphosphoryl with up to 4 carbon atoms per alkyl moiety, or PA1 R.sup.4 and R.sup.5, conjointly with the…
