Description: Despite the well-documented need for midstory control in bottomland hardwood regeneration, little research has documented the efficacy of such efforts, or the potential negative effects on nontarget stems. More than 72,000 midstory stems located on 90 acres of northern Mississippi bottomland hardwood forest were injected with an imazapyr solution during August 2009. Crown reduction in injected stems was 96.8 percent at 1 year after treatment, with a range of 91.8 to 100 percent by species. Nontarget impact attributed to improper injection technique was observed in one location, but the minor foliar symptoms are not expected to result in long-term damage. No nontarget impacts were observed in other trees on the study site. Residual crop trees did not exhibit negative symptoms from the injection. Injection is effective for controlling midstory stems found in bottomland hardwoods and has a negligible effect on nontarget stems. Midstory injection is often a crucial component of regeneration in bottomland hardwoods and should continue to be used by land managers.
