There are described novel substituted 3-arylamino-6-trifluoromethyluracils of the formula I, processes for their preparation, and methods of controlling monocotyledonous and dicotyledonous harmful plants in agricultural and silvicultural crops. ##STR1## In formula I, the radicals R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are not only hydrogen, alkyl and haloalkyl, but can also have further meanings, R.sup.5 is alkyl or amino, and X is CH or N.

Herbicidal 3-arylamino-6-trifluoromethyluracils

There are described new 2-imino-1,3-dithietanes of general formula I ##STR1## in which R is the group ##STR2## in which A is CFHal, C(CH.sub.3)C.sub.1-4 -alkyl, C(CH.sub.3)CHal.sub.3, C(CH.sub.3)CF.sub.2 Cl, C(CH.sub.3)CFCl.sub.2, C.sub.2 H.sub.4, C.sub.2 H.sub.3 Hal, C.sub.2 H.sub.2 Hal.sub.2, C.sub.2 HHal.sub.3, C.sub.2 F.sub.2 Cl.sub.2, C.sub.2 F.sub.4 or C.sub.2 F.sub.3 Cl, in which Hal is F or Cl, Y is nitrogen or CH, R.sup.1 is fluoro-C.sub.1-12 -alkyl, fluoro-C.sub.2-12 -alkenyl, fluoro-C.sub.2-12 -alkynyl, fluorocyclopropyl or fluorocyclopropylmethyl; X is oxygen or sulphur, 2 is defined in the specification and n is 0, 1 or 2, as well as their acid addition salts, a process for their preparation and their use as pesticides. The new compounds are especially useful as nematicides.

2-imino-1,3-dithietanes, their use as pesticides

A substituted carbanilic acid ester of the formula ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkinyl, chlorinated C.sub.1 -C.sub.6 -alkyl or phenyl-C.sub.1 -C.sub.5 -alkyl, R.sub.2 is hydrogen or chlorine, R.sub.3 is hydrogen or C.sub.1 -C.sub.6 -alkyl, R.sub.4 is hydrogen, C.sub.1 -C.sub.6 -alkyl or phenyl which latter may also be substituted, R.sub.5 is halogen, and R.sub.6 is hydrogen or halogen. The compounds of the invention have a surprisingly high compatibility with rice, wheat, barley, oats, rye, and agricultural grasses when applied in a postemergence procedure. They also have a high activity against weeds of various resistant genera.
