The present invention relates to novel phenylimidazolone compounds of the formula ##STR1## wherein A is a bond or C.dbd.T; R is --H, Alk, halo-Alk, cyano-Alk, or phenyl; R.sup.1 is --H, Alk, halogen, halo-Alk, --CN; or when A is a bond, R and R.sup.1 may together form a saturated, partially saturated, or unsaturated three to seven member carbon ring, and the ring may be substituted at any position independently with one or more Alk, --O--Alk, --CN, halogen, --OH, or .dbd.O groups; T is O or S; U is --H; V is --OH, or U and V may together form a bond; W is halogen or --CN, and when W is halogen, R.sup.1 is --CN; X is --H or halogen; Y is --H, halogen, --CN, Alk, --CF.sub.3, or --OCF.sub.3 ; Z is --H, halogen, --OH, Alk, aryloxy, C.sub.1-6 acyl, --NH.sub.2, --NO.sub.2, --NR.sup.2 SO.sub.2 R.sup.2, --N(SO.sub.2 R.sup.2).sub.2, --NR.sup.2 COR.sup.2, or B; or Y and Z may together form a saturated, partially saturated, or unsaturated three to seven member carbon ring, wherein each carbon may be independently replaced with N, O, or S, and the ring may be substituted at any position independently with one or more Alk, --O--Alk, .dbd.O, --SO.sub.2 R.sup.2, or C.sub.1-6 acyl groups; Alk is a straight, branched, or cyclic saturated or unsaturated C.sub.1-6 hydrocarbon group; B is --O--Alk, wherein each carbon may be independently replaced with one or more O or S groups, and optionally substituted with one or more halogen or C.sub.1-6 acyl groups; or the agriculturally acceptable salts, amides, and esters thereof. The compounds are useful as herbicides.
