Herbicides propazine, 2,4-D, dicamba, picloram, tebuthiuron, and hexazinone were applied at rates of 0.14 to 2.24 kg/ha pre- and postemergence to greenhouse-grown kleingrass plants. Kleingrass was tolerant to premergence sprays up to and including 1.2 kg/ha of propazine and 0.56 kg/ha of 2,4-D. All other herbicides and rates were phytotoxic to emerging kleingrass. At the early postemergence stage, kleingrass tolerated rates up to and including 0.28, 0.56, and 0.56, and 1.12 kg/ha of picloram, 2,4-D, dicamba, and propazine, respectively; but it did not tolerate tebuthiuron or hexazinone at any rate. At the intermediate vegetative stage (5 to 12.5 cm tall), kleingrass tolerated picloram, 2,4-D, dicamba, and propazine at rates of 0.56, 1.12, and 2.24 kg/ha, respectively, without injury. Mature kleingrass tolerated higher rates of all herbicides than did earlier stages of growth.
