Description: Downy brome or cheatgrass (Bromus tectorum L.) is one of the most invasive and widespread exotic plants in North America. Downy brome can reduce soil nutrient availability, alter native plant community composition, and increase fire frequencies. The effectiveness of Plateau® imazapic herbicide in reducing downy brome cover has been variable, and there is uncertainty about the impacts of imazapic on native species. Researchers from Flagstaff, Arizona, recently published an article in Invasive Plant Science and Management that investigated if treatments of imazapic and/or seeding with native shrubs were effective in rehabilitating shrublands highly invaded by downy brome on the Kaibab National Forest in northern Arizona. Researchers also determined the effects of imazapic on different growth stages of both downy brome and three native shrub species in the greenhouse.
