Novel herbicidal compounds, compositions containing them, and methods for their use in controling weeds are disclosed. The novel herbicidal compounds are optionally substituted phenylmethoxy or phenylmethylthio heterocycles of the formula: <IMAGE>GE> R=halogen; R1=lower alkyl, lower alkoxy, lower haloalkyl, lower haloalkoxy, lower alkylthio, lower sulfonyl, or lower alkylsulfinyl; R2=lower alkyl, or lower haloalkyl; X=H, halogen, or lower alkyl; W=O or S; Z, Z1, Z2 are independently selected from H, halogen, straight or branched chain lower alkyl, lower alkoxy, is lower haloalkoxy, cyano, lower cyanoalkyloxy, or aryl; or Z and Z1 are adjacent to each other on the benzene ring, and taken together are -(CH2)4-; or Z2 is OA in the 2-, 3-, or 4-position of the phenyl ring; A is a derivative of an alkanoate bonded to the phenoxy oxygen at the alpha carbon; R3 is H or lower alkyl; R4=OH or an agriculturally acceptable salt thereof, straight or branched chain lower alkoxy, lower haloalkoxy, alkoxyalkoxy, alkoxyalkoxyalkoxy, amino, lower alkylamino, lower alkylsulfonylamino, or lower (alkyl)(alkylsulfonyl)amino; and R5=halogen or lower alkyl ester. |
