Herbicidal combinations containing 2-?(4-heterocyclic-phenoxymethyl)phenoxy!alkanoates

Herbicidal compositions containing herbicidal 2-?(4-heterocyclic-phenoxymethyl)phenoxy!alkanoates in combination with other herbicides are disclosed. The herbicidal 2-?(4-heterocyclic-phenoxymethyl)phenoxy!-alkanoates are of the formula STR1 in which R' is methyl, W is oxygen, Q is STR2 R is hydrogen, M, lower alkyl; cycloalkyl comprising from 3 to 6 carbon atoms; lower alkenyl; or lower alkynyleach optionally substituted with one or more chlorine or fluorine, or --?CHR7 --(CH2)m O!n R8 ; each of R1 through R5 is lower alkyl or lower haloalkyl; R6 is lower alkyl, lower haloalkyl, lower cyano-alkyl, lower alkoxyalkyl, lower alkoxycarbonylalkyl, lower arylalkyl, or amino; R7 is hydrogen or methyl; R8 is lower alkyl; X is hydrogen, methyl, fluorine, or chlorine; Y is hydrogen; Z is hydrogen, fluorine, chlorine, bromine, lower alkyl, or methoxy; Z' is hydrogen, fluorine, or chlorine; Z and Z' taken together may be --(CH2)4 -- to form a tetrahydronaphthyl moiety; m is 0 to 2, and n is 1 to 6; and M is sodium, potassium or ammonium. These herbicidal alkanoates are used with either grass-controlling or broadleaf herbicides.

3-[4-(phenylmethoxy)phenyl]-1-substituted-6-haloalkyl-uracil herbicides

The present application discloses herbicidal 3-[4-(phenylmethoxy)phenyl]-1-substituted-6-haloalkyluracils of the formula STR1 in which M is lower alkyl, lower 2-alkenyl, lower 2-alkynyl, lower alkoxymethyl or lower haloalkyl; T is lower haloalkyl; and U,

Herbicidal 2-[(4-heterocyclic-phenoxymethyl)phenoxy]-alkanoates

Herbicidal compounds, compositions containing them, and a method for controlling weeds by application of the compositions are disclosed. The herbicidal compounds are 2-[(4-heterocyclic-phenoxymethyl)phenoxy]alkanoates of the formula STR1 in which A is a derivative of an alkanoate bonded to the phenoxy oxygen at the alpha carbon, and Q is 4-difluoromethyl-4,5-dihydro-3-methyl-l,2,4-triazol-5(1H)-on-1-yl, 3,4,5,6-tetrahydrophthalimid-1-yl, 1-(1-methylethyl)imidazolidin-2,4-dion-3-yl, 1,4-dihydro-4-(3-fluoropropyl)-5H-tetrazol-5-on-1-yl, 3-chloro-4,5,6,7-tetrahydroindazol-2-yl, 4-methyl-l,2,4-triazine-3,5-dion-2-yl, 8-thia-1,6-diazabicyclo[4.3.0]-nonane-7-on-9-ylimino, or 1-methyl-6-trifluoromethyl-2,4-pyrimidinedione-3-yl; X is hydrogen, methyl, fluorine, or chlorine; Y is hydrogen; W is oxygen or sulfur; Z is hydrogen, fluorine, chlorine, bromine, lower alkyl, or methoxy; Z' is hydrogen, fluorine, or chlorine; and the group AO-- may be in the 2, 3, or 4-position of the phenyl ring.
