Abstract

Different combinations of chemical site prep and post-plant herbaceous weed control installed at three Upper Coastal Plain locations were compared in terms of year 3 loblolly (Pinus taeda L.) pine response to determine the better vegetation management regimes. Site prep treatments were different herbicide rates applied in either July or October. Site prep treatments were followed by different herbaceous weed control application timings. July site prep applications performed better than October applications and the higher site prep herbicide rates performed better than the lowest rate. First year herbaceous weed control was more important than second year but first plus second year had the greatest response. Year 3 pine response to the operational vegetation management regime of July chemical site prep with first year herbaceous weed control was comparable to or exceeded year 3 pine response to complete weed control reported in a previous research experiment conducted on similar sites.
