Abstract

Sweet pecan, a prized species for use in fine furniture and paneling, is subject to branch and terminal damage by the pecan twig girdler that could cause deformities in the trees. In the young plantation studied, 55 percent of the trees in disked plots and 40 percent in mowed plots were damaged by the twig girdler, but only 19 percent in control plots were damaged. Twig girdlers had easier access to trees in mowed and disked plots because trees were larger, and other woody and herbaceous plants had been reduced or eliminated. Trees were smaller in control plots and had been overtopped by the competing vegetation.
