Abstract

Eastern baccharis (Baccharis halimifolia L.) is a frequent invader in bottomland hardwood plantations established in southeastern Arkansas. This dioecious shrub can affect the survival and growth of newly planted stems. This study evaluated the utility of various herbicides and mechanical control treatments to manage eastern baccharis in an established hardwood plantation. Of the four herbicide treatments used, a dormant season application of triclopyr was the most effective treatment. As a non-chemical treatment option, two annual dormant and growing season cuttings resulted in 43 and 26 percent mortality, respectively, of the eastern baccharis rootstock. No damage was visible to any of the planted hardwood stems after two growing season for any of the management options tested.
