Early or late over-the-top applications of herbicides were used to control herbaceous competition in machine planted loblolly pine (Pinus taeda L) seedlings at two locations in a pasture near Alleene and hand planted seedlings on a bedded site near Fouke. Sites were selected for diverse competitors. None of the treatments controlled weeds for the entire growing season. Only glyphosate + sulfometuron methyl produced seedling survival and growth below the check plots. The best over-the-top treatments were sulfometuron methyl alone or sulfometuron methyl + hexazinone.
