ABSTRACT:
A liquid herbicide applicator mechanism mountable on a farming vehicle for wipingly applying the herbicide on undesired vegetation growing in a cultivated field. The applicator mechanism includes a tool bar for carrying a plurality of herbicide dispenser assemblies so that they alternately align with the rows of crop plants and the spaces therebetween as the vehicle moves through the cultivated field. Each of the herbicide dispenser assemblies receives the herbicide from a reservoir tank under the influence of gravity and has a herbicide wiper head which absorbs the herbicide for wiping application on the undesired vegetation. Each of the herbicide wiper heads is substantially rigid but deformably configurable so that it may be shaped into substantial conformity with the contour of the crop plant rows and the spaces in the cultivated field and each wiper head is provided with special absorbent wiper elements.
