Abstract

Hexazinone is a commonly used herbicide for release of red pine in the Lake States from competing vegetation. The label is specific regarding time of application, recommended rate, and target species. Label recommendations were tested by using the herbicide on dates in April, May, and July at specified rates with broadcast band and spot applications over 3-0 red pine. Results show that exceeding label rates can damage red pine. Hexazinone satisfactorily controlled aspen, cherry, serviceberry, raspberry and various grasses, but was not effective for control of hazel species. Spraying too late in the growing season caused delayed response. These findings are applicable to forest managers in the Lake States and elsewhere who are establishing red pine or working with the control of similar vegetation.
