Abstract
Twelve, 16-ha study sites were established in recently harvested (1980) stands of natural pine-mixed hardwoods located in the Piedmonts of South Carolina and Georgia. Treatments applied were control (no site preparation), herbicide/burn (3.4 kg a.e. glyphosate/ha), chop/burn, shear/disc, shear/V blade/disc, shear/pile, and shear/pile/disc. Measurements collected after two growing seasons included pine height, diameter, and occurrence of pine tip moth (Rhyacionia spp.) infestation on the terminal shoot. After the second growing season, tree volume was 58% greater on mechanically-treated areas compared to the control and herbicide/burn areas. Average pine tip moth incidence was 15% for the control treatment and ranged from 24 to 36% for the other six treatments. Although the disced treatments had higher tip moth infestation (32 to 36%) compared to the control plots (15%), pine growth was significantly greater for treatments involving discing.
