Compounds of formula (I) are disclosed, wherein: R<1> represents H, (C1-C8)-alkyl, where appropriate substituted with a halogen, cyano, (C1-C4)-alkoxy, aryl and substituted aryl, or (C3-C6)-alkenyl, (C3-C6)-alkinyl or (subst.) aryl or an agriculturally suitable cation; R<2> and R<3> independently of one another represent (C1-C4)-alkyl, -haloalkyl, -alkoxy or -haloalkoxy, -halogen, or mono- or di[(C1-C4)-alkyl]amino; R<4> represents H, a halogen, (C1-C4)-alkyl, -alkoxy or -alkoxy carbonyl, nitro, cyano or a group Q; X represents O or S, Y represents CH or N, W represents O, S, N-OR<5>, N-NR<5>R<6>; R<5>, R<6> represent H, (subst.) (C1-C4)-alkyl, (C3-C6)-alkenyl, (C3-C6)-alkinyl or (subst.) aryl or, together with the N atom, a (subst.) heterocyclic group with 3-7 ring atoms; and Q represents a group of formula (a), wherein R<2'>, R<3'>, X' and Y' are defined by analogy with R<2>, R<3>, X and Y in formula (I). The proposed compounds are suitable for use as herbicides and plant growth regulators. They can be manufactured by the processes disclosed in claim 5. |
