Fall is a good time to control weedy brome species, such as downy brome, Japanese brome and Cheat. 0000000016 00000 n Cheatgrass, also known as downy brome, is an invasive annual that dominates more than 100 million acres of the Great Basin in the western U.S. Germinating each winter, cheatgrass grows furiously in spring and dies in early summer, leaving the range carpeted in golden dry tinder. Most grasses have round stems, but several others have distinctly flat stems. Downy brome is a winter annual, which means it germinates in the fall. Downy brome is primarily a weed of landscapes, fencerows, pastures, hay fields, and occasionally winter small grain crops. Scientific Name: Bromus tectorum L.

Mack, R. N. 1981. Most Bromes found in Minnesota have sheaths and nodes that are hairy to various degrees and are mostly distinguished by the number of veins on the glumes, length of the lemma awns, and sometimes leaf characteristics. U.S. Habitat: Downy brome grows in many climatic areas and will grow in almost any type of soil. xref It can grow in a wide variety of habitats, and is troublesome in winter wheat-based systems, alfalfa, Conservation Reserve Program (CRP) lands, rangelands, fencerows, and railroad right-of-ways.
