Picloram combined with 2,4,5-T (1:1) at 0.56 or 1.12 kg/ha was the most effective of several herbicides and herbicide combinations applied in the fall for control of Macartney rose. Aerial application of the 2,4,5-T/picloram combination at 1.12 kg/ha reduced Macartney rose canopies on Texas Coastal Prairie rangeland by 70 to 80% after a year. The same rate of 2,4-D, the standard treatment, reduced the canopies by 40 to 50%. The herbicide combination was equally effective whether applied in water containing 0.5% (v/v) of commercial surfactant or in a diesel oil:water (1:4) emulsion. Herbicides more effectively controlled undisturbed Macartney rose than plants that previously had been shredded or sprayed. Increasing the volume of carrier from 47 to 94 liters/ha did not adequately increase Macartney rose control to justify extra application costs associated with the higher spray volume.
