Claim:
An oxazin(ethi)one compound of the formula I in which the variables Z, A, n, R 1 , R 2 and R 3 are as defined below: Z is oxygen or sulfur, A is a 5- or 6-membered carbocycle or a 5- or 6-membered heterocycle having 1, 2 or 3 heteroatoms selected from the group consisting of N, O and S, each of which cycles is fused to the oxazin(ethi)one ring via two carbon atoms; n is a number from 0 to 4; R 1 is hydrogen, is C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, C 2 -C 6 -alkynyl, which are in each case unsubstituted or substituted by O—R 4 , C(O)O—R 5 , NR 6 R 7 , C(O)NR 6 R 7 , S—R 8 , C 3 -C 8 -cycloalkyl, phenyl or by 5- or 6-membered saturated or unsaturated heterocyclyl having 1 to 3 heteroatoms selected from the group consisting of N, O and S, where phenyl and heterocyclyl may be mono-, di- or trisubstituted by C 1 -C 6 -haloalkyl, C 2 -C 6 -haloalkenyl or C 2 -C 6 -haloalkynyl; R 2 is C 1 -C 3 -alkyl, C 1 -C 3 -haloalkyl or cyclopropylmethyl; R 3 is halogen, cyano, C 1 -C 6 -alkyl, C 1 -C 6 -haloalkyl, C 1 -C 6 alkoxy or C 1 -C 6 -haloalkoxy; and in which R 4 , R 5 independently of one another are hydrogen, C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, C 2 -C 6 -alkynyl, C 1 -C 6 -haloalkyl, C 2 -C 6 -haloalkenyl, C 2 -C 6 -haloalkynyl, hydroxy-C 1 -C 4 -alkyl, hydroxycarbonyl-C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl or C 1 -C 4 -alkoxycarbonyl-C 1 -C 4 -alkyl; R 6 , R 7 independently of one another are hydrogen, C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, C 2 -C 6 -alkenyl, C 2 -C 6 -alkynyl, C 1 -C 6 -haloalkyl, C 1 -C 6 -haloalkoxy, C 2 -C 6 -haloalkenyl, C 2 -C 6 -haloalkynyl, hydroxy-C 1 -C 4 -alkyl, hydroxycarbonyl-C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl or C 1 -C 4 -alkoxycarbonyl-C 1 -C 4 -alkyl; R 6 and R 7 together with the nitrogen atom to which they are attached may also form a 5-, 6- or 7-membered saturated N-heterocycle which may contain a further heteroatom selected from the group consisting of O, N and S and/or which may be substituted by 1 to 4 C 1 -C 6 -alkyl groups; R 8 represents C 1 -C 6 -alkyl, C 2 -C 6 -alkenyl, C 2 -C 6 -alkynyl, C 1 -C 6 -haloalkyl, C 2 -C 6 -haloalkenyl, C 2 -C 6 -haloalkynyl, hydroxy-C 1 -C 4 -alkyl, hydroxycarbonyl-C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl or C 1 -C 4 -alkoxycarbonyl-C 1 -C 4 alkyl; and the agriculturally useful salts of the oxazin(ethi)one compound I.
