Streamline Basal Application of Herbicide for Small-Stem Hardwood Control
Abstract. The effectiveness of low-volume b a s a lapplication of herbicide - "streamline" application - was evaluated on 25 hardwood species and loblolly pine. Test mixtures were step-wise rates of Garlon 4 mixed in diesel fuel with a penatrant added. Most comparisons tested 1O%, 20%, and 30% mixtures of Garlon 4, while tests with saplings and small trees used 20%, 30%, and 40%. Target stemsranged from 2 ft tall to 6 in. dbh. Applications were made in February, using pressure-regulated handguns equipped with straight stream nozzles attached to backpack sprayers. Two bands of the herbicide mixture were applied to two sides of all stems.
