ABSTRACT:
It has now been found that certain novel (oxaalkyl)phenyl-substituted heterocycles are useful as pre-emergent and post-emergent herbicides. These compounds are represented by formula I: ##STR1## where Q is a heterocycle and X, Y, R, R.sup.1, R.sup.2, and R.sup.3 are substituents as described in the specification. Preferred are those compounds where Y and R are chloro; R.sup.1 and R.sup.2 are hydrogen or methyl; R.sup.3 is hydrogen or alkylaminocarbonyl; X is fluorine; and Q is a 1-substituted-6-trifluoromethyl-2,4(1H,3H)-pyrimidinedion-3-yl.
