<p>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?1 and R2¿ are each independently C¿1?-C6 alkoxy, C2-C6 haloalkoxy, C1-C6 alkylthio or C2-C6 haloalkylthio; or R?1 and R2¿ are taken together to form -X1-(CH2)r-X2-, -(CH¿2)s-X?3-, -(CH¿2?)t-X?3-CH¿2-, -(CH2)v-X3-CH2CH2- or -(CH2)w-, each group optionally substituted with at least one member selected from 1-6 halogen, 1-6 CH3 and one C1-C3 alkoxy; or R?1 and R2¿ are taken together to form -O-N(C¿1?-C3 alkyl)-CHR?12-CH¿2- or -O-N=CHR12-CH2-, each group optionally substituted with at least one member selected from 1-2 halogen and 1-2 CH3; or R?1 and R2¿ are taken together with the carbon to which they are attached to form C(=O) or C(=S); and R?3-R10, X1-X3¿, 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).</p> |
