| Abstract: |
a method is disclosed for the control of nematodes which comprises applying to the situs of infestation certain N-aminosulfenyl carbamates of the formula ##STR1## N-arylsulfenyl carbamates of the formula ##STR2## or N-acylamidosulfenyl carbamates of the formula ##STR3## wherein R.sub.1 and R.sub.2 are each independently selected from straight or branched chain alkyl or alkoxyalkyl having 1 to 8 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, phenyl, halophenyl, phenyl(lower)alkyl, halophenyl(lower)alkyl and loweralkoxybenzyl; and wherein R.sub.1 and R.sub.2 may be taken together with the nitrogen to form an optionally substituted heterocyclic ring of 5 to 8 members which may contain one additional hetero atom consisting of oxygen, sulfur, or nitrogen; R is ##STR4## WHEREIN EACH X is independently selected from halogen and lower alkyl, and n is an integer of 0 to 5 inclusive; and R.sub.3 is hydrogen or lower alkyl and R.sub.4 is straight or branched chain alkyl having 1 to 7 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, phenyl, or benzyl; and wherein R.sub.3 and R.sub.4 may be taken together with the carbonyl and the nitrogen to form an optionally substituted heterocyclic ring of 5 to 8 members, which may contain one additional hetero atom selected from oxygen, nitrogen, and sulfur. |
