Abstract
Twenty-two treatments replicated four times were applied to planted loblolly pine, Pinus taeda L. on bedded industrial forest land in east Texas for measurement of growth impact of Nantucket pine tip moth (NPTM), Rhyacionia frustrana (Comstock), and effects on pine growth over 2 years. Treatments were combinations of Velpar, Oust, and Arsenal herbicides and diammonium phosphate (OAP) fertilizer with treatments in 2000, or both 2000 and 2001 . Ten of the treatments were treated with Mimic timed with pheromone traps to reduce NPTM infestations. Mimic was an effective control, and there was a small but significant increase in the loblolly pine growth at the end of the second growing season. The best growth of pines with the most intensive treatments was equal with and without NPTM control. NPTM control did, however, make a difference on intermediate treatments.
