Abstract

In order to develop multiple treatment options for managing yaupon (Ilex vomitoria), a study was conducted in 2002 and 2003 at the Gus Engeling Wildlife Management Area (WMA) in Anderson County, which is located within the Post Oak Savannah Ecological Region of Texas. Treatment combinations of mechanical removal by cutting, basal applications of herbicides, and mechanical removal plus cut-stump applications of herbicides were evaluated during March and June. Twenty-five replicates (shrubs) of each treatment were applied in March and June in a completely random design. Herbicide treatments were individual plant treatment (IPT) basal applications of 0, 5, 10, 20, and 25% concentratios of Garlon 4 delivered in diesel. Mechanical-plus-herbicide treatments were cut and then treated with 0, 5, 10, 20, or 25% Garlon 4 in diesel only. Mortality was evaluated 15 months after treatment applications in June 2003 for March treatments and September 2003 for June treatments. IPT applications of 25% concentrations of Garlon 4 were no more effective than 10% concentrations of Garlon 4 and, in some cases, no more effective than diesel alone. Furthermore, it was not necessary to apply 25% concentrations of Garlon 4 to achieve very high yaupon control.
