Compounds of Formula (I), and their agriculturally suitable salts, are disclosed which are useful for controlling undesired vegetation wherein Q is (Q-1) or (Q-2); R.sup.1 and R.sup.2 are each independently C.sub.1 -C.sub.6 alkoxy, C.sub.2 -C.sub.6 haloalkoxy, C.sub.1 -C.sub.6 alkylthio or C.sub.2 -C.sub.6 haloalkylthio; or R.sup.1 and R.sup.2 are taken together to form --X.sup.1 --(CH.sub.2).sub.r X.sup.2 --, --(CH.sub.2).sub.s --X.sup.3 --, --(CH.sub.2).sub.t --X.sup.3 --CH.sub.2 --, --(CH.sub.2).sub.v --X.sup.3 --CH.sub.2 CH.sub.2 -- or --(CH.sub.2).sub.w --, each group optionally substituted with at least one member selected from 1-6 halogen, 1-6 CH.sub.3 and one C.sub.1 --C.sub.3 alkoxy; or R.sup.1 and R.sup.2 are taken together to form --O--N(C.sub.1 -C.sub.3 alkyl)--CHR.sup.12 --CH.sub.2 -- or --O--N.dbd.CHR.sup.12 --CH.sub.2 --, each group optionally substituted with at least one member selected from 1-2 halogen and 1-2 CH.sub.3 ; or R.sup.1 and R.sup.2 are taken together with the carbon to which they are attached to form C(.dbd.O) or C(.dbd.S); and R.sup.3 -R.sup.10, X.sup.1 -X.sup.3, X, Y, Z, k, m, p, q, r, s, t, v, w, and x are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (I) and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula (I). ##STR1##
