Abstract
Substituted aryl ether derived compounds represented by the general structure (I) are described. X and Y are independent of each other and are represented by hydrogen, halogen, cyano, nitro, (C1-4)alkyl, (C1-4)haloalkyl, or (C1-4)haloalkoxy; Z is oxygen or sulfur; Q is selected form Q1 to Q6; Also described are the processes for the manufacture of these compounds and agriculturally suitable compositions containing these as active ingredients which are useful as herbicides for general or selective pre-emergent or post-emergent control of undesired plant species and defoliants.
