Abstract

Three herbicide products, Roundup© (glyphosate), Pronone© 10G (hexazinone), and Velpar© L (hexazinone), were applied aerially to release a 4-year-old loblolly pine plantation from hardwood competition. Herbicide damage to pines was not excessive. Post-treatment growth of pines in herbicide-treated plots was not significantly different from growth of pines in untreated check plots.
