Extract

Competition of downy brome (Bromus tectorum L.) with seeded perennial grasses is an important factor in the lack of success of many seedings on sagebrush conversion areas in the Great Basin. The seriousness of downy brome competition was emphasized by Stewart and Hull. Their work in Idaho indicated repeated failure in seeding of crested wheatgrass (Agropyron cristatum [L.] Gaertn.) on areas where downy brome was not eliminated or reduced. Hull and Pechanec pointed out that many studies indicate that reduction of dense stands of downy brome is essential for the early establishment of seeded species. They also note that in some cases seeding of perennials has been successful without reduction of this weedy annual grass.
