A method for selectively applying cut-stump treatment herbicides to cut surfaces of undesirable hardwoods for stump-sprout control combined with the operation of a feller-buncher tree harvester and six-year growth results of 1-0 out-planted bareroot loblolly pine (Pinus taeda L.) is presented. The herbicide application system consists of a low cost 12-V dc electric-powered sprayer attachment installed on a feller-buncher shear head. After two growing seasons, hardwood stump sprouting in the feller-buncher-sprayer treated plots was as low as 5% while sprouting was as high as 67% in the untreated plots. After six years, survival, diameter, and height growth of pine planted in the machine-applied herbicide treatment plots was significantly higher than in similar untreated control plots.
