The active substances of the new compositions correspond to the formula ##STR1## wherein X is chlorine or bromine, A represents a radical --SR.sub.1 or --NR.sub.2 R.sub.3, B represents a radical --SR.sub.1, --NR.sub.2 R.sub.3 or --OR.sub.4, and C represents a radical --SR.sub.1, --NR.sub.2 R.sub.3, --OR.sub.4 or the methyl or benzyl group. The symbols R.sub.1 to R.sub.4 are chosen from substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl and benzyl groups, R.sub.2 can also be hydrogen and R.sub.2 together with R.sub.3 and the adjacent nitrogen can form a heterocyclic ring system.
