    Description

    After thinning hardwood stands, sprouts often develop on the girdled stems or cut stumps. While sprouts may be left for wildlife, it is usually best to deaden each tree to minimized future competition for soil moisture and nutrients. By applying select herbicides to the stump, sprouting can be eliminated. This study evaluated five herbicides applied as basal bark or cut stem application to black walnut and green ash stumps 90 days after cutting. Trimec®, Crossbow®, Chopper®, Vista®, and Garlon 4® were applied in diesel oil solutions. All herbicides effectively controlled stump sprout when applied in a 3- to 4-inch-wide basal bark application around the base of the stump. Only Vista® was effective as a cut surface application to 18-inch-high stumps of both black walnut and green ash. Cut surface application showed species specific responses where Chopper was effective on black walnut but not green ash while Garlon 4® was effective on ash but not walnut.
