DescriptionTree vigor, live crown ratios, dieback, and survival of hardwood competition were monitored for 2 years following a fall application (16 ounces per acre) of imazapyr on 4 stands of loblolly pine (Pinus taeda L.) in the Gulf Coastal Plain of Louisiana and Arkansas. Assessments during the first growing season following application indicated that 87 to 98 percent of the hardwood stems were completely defoliated or had 80 percent or more crown dieback. The lowest levels of defoliation and dieback occurred in the densest stands. Typically, the crowns of the recovered hardwoods had some level of dieback, but live crown ratios of these trees were similar to those found in control areas. Differences in mortality and recovery were evident among species.
