Abstract
3-Aryluracil derivatives of the formula I ##STR1## in which --W-- is the group ##STR2## where the ring nitrogen atom is bonded via the C atom; R.sub.1 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.3 alkenyl or C.sub.4 alkenyl or C.sub.3 alkynyl or C.sub.4 alkynyl; PA0 R.sub.2 is halogen or cyano; PA0 R.sub.3 is hydrogen or halogen; PA0 R.sub.4 is hydrogen, halogen or C.sub.1 -C.sub.4 alkyl; PA0 R.sub.5 is C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 haloalkyl; or R.sub.4 and R.sub.5 together are --(CH.sub.2).sub.n --; PA0 n is the number 3 or 4; PA0 R.sub.13 is C.sub.1 -C.sub.4 alkyl, C.sub.3 alkenyl or C.sub.4 alkynyl or C.sub.3 alkynyl or C.sub.4 alkynyl; and PA0 Q is one of the groups a) to e): ##STR3## where R.sub.6 to R.sub.12 are substituents, m is 3, 4 or 5, X is oxygen or sulfur and t is 2, 3 or 4, and if R.sub.1 is hydrogen, the agrochemically acceptable salts of compounds of the formula I. the compounds of formula I have herbicidal properties and are suitable as the active ingredient in a herbicide.
