Timing of Disturbance after Herbicide Applications for Chemical Site Preparation
Four herbicide combinations were screened for efficacy on selected hardwoods relative to four timings of postapplication disturbance. Garlon 4®, Garlon 4 plus Esteron 99®, Garlon 4 plus Tordon 101®, and Garlon 4 plus Tordon K® were applied in the spring to Piedmont and Coastal Plain sites in a replicated experiment. The best hardwood control was achieved when the disturbance occurred at least six to eight weeks after application. Chestnut oak (Quercus prinus L.) control was successfully predicted on the basis of leaf tissue moisture content and environmental data. Only Garlon 4 plus Esteron 99 failed to give good overall control of hardwood brush. South. J. Appl. For. 12(2):124-127.
