<p>Herbicidal 3-(bicyclic nitrogen-containing heterocycle)-substituted-1-methyl-6-trifluoromethyluracils, compositions containing them, and methods of using them to control undesired plant growth are disclosed. The herbicidal compounds of the present invention are defined by generic structure (I), in which V is N or C-R1; R is hydrogen, straight or branched chain alkyl, alkenyl, alkynyl, hydroxyalkyl, alkoxyalkyl, haloalkyl, alkoxycarbonylalkyl, arylalkyl, optionally substituted with halogen, or aminocarbonylalkyl in which the amino nitrogen is substituted with arylalkyl or one or two alkyl; R1 is hydrogen, alkyl, haloalkyl, or cyano; R2 is lower alkyl or amino; and X is hydrogen or halogen, with the proviso that each aliphatic component has not more than six carbon atoms.</p> |
