Koa Regeneration
Grass Suppression for Koa Regeneration
Dr. James Leary, UH-CTAHR, conducts herbicide trials at the Kona Hema Reserve to control grasses suppressing regrowth of koa seedlings (Acacia koa) using glyphosate (Roundup®), fluazifop-p-butyl (Fusilade®), and imazapyr (Habitat®). Dr. Leary also demonstrated use of a hands-free spraying system and evaluates the impacts of imazapyr on other native species (‘ohia, Metrosideros polymorpha). [7:02 min]
