Bromus is a large genus of grasses, classified in its own tribe Bromeae. [ 2 ] [ 3 ] They are commonly known as bromes , brome grasses , cheat grasses or chess grasses . Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species.
Mechanical weed control is a physical activity that inhibits unwanted plant growth. [1] Mechanical, or manual, weed control techniques manage weed populations through physical methods that remove, injure, kill, or make the growing conditions unfavorable.
The species has a wide host range that includes all large-stemmed grasses except oats (Avena sativa). [3] Specifically, it feeds on wheat (Triticum aestivum), durum (T. durum), barley (Hordeum vulgare), rye (Secale cereale), wheatgrass (Agropyron spp.), timothy (Phleum spp.), Elymus spp. and cheatgrass (Bromus tectorum).
