Abstract: The present invention provides an apparatus and method particularly well suited for cutting vegetation and applying chemical fluids to the stump efficiently over wide areas, particularly with common mechanical devices such as sickle bar trimmers, rotary mowers, and flail mowers. Furthermore, the chemical fluids are precisely applied to the desired vegetation stumps so that the biomass has low chemical residue and the chemicals does not disturb the soil. Therefore, the biomass is preserved, soil residues are reduced, chemical waste is reduced, undesired vegetation is treated with a correct dosage, and manual labor is dramatically reduced. Thus, the soil residues are reduced and the biomass is preserved for further downstream processes.
