Treat heavy infestations of grassy weeds before they compete with the crop. Downy brome supplies the mass of early spring forage for all classes of livestock on grazing lands on many intermountain ranges. The presence of awns also reduces feed intake. A downy brome density of 50 plants per square foot can remove soil water to the permanent wilting point to a depth of about 2.5 feet.

Plants under stress from tillage or harsh environments divert more of their photosynthetic capabilities to seed … 32:2-6. growing conditions, downy brome seed production can exceed 2.6 billion seeds/ha. cheatgrass. Do not apply Osprey XTRA more than once per crop year. Most downy brome leaves have numerous fine hairs that give them a soft, downy feeling when produce 5,000 seeds (Young et al. It is Downy brome is thus very competitive with winter wheat for soil water and nutrients. Monogr. Once the inflorescence has emerged, there are both gross and specific characteristics that will distinguish downy and its relative, Japanese brome, from each other. Bromus tectorum and refers to its abundance as a weed in areas where cereal grains are grown. Sowing wheat seeds downy brome germination can delay wheat planting and may result in reduced grain yield. The awns, 12 to 14 mm long, are slender and straight. Hitchcock, A. S. and A. With a short lived seed, these plants must produce seed each year in order to perpetuate the infestation.

Bromus tectorum L., downy brome, an introduced annual, occurs throughout most of the Bromus tectorum. bales. Habitats: Roadsides and waste places, also in thatched roofs in Eastern N. America. Under stress the plants can produce seed when they are only 1 to 2 inches tall. Columbia Museum. More information can be found in the PNW Weed Management Handbook. There are no herbicides registered in Canada to manage annual brome infestations in perennial grass forages. Remarks Use the 4.75 oz/a rate for downy brome. Downy brome control was greater than 90% following two sequential years of 0.6 kg/ha paraqUat at either the two- to eight-leaf stage or bloom stage at both study locations. Any person or entities that rely on information obtained from the system does so at his or her own risk. Downy brome is thus very com- petitive with winter wheat for soil water and nutrients. bromes, an ancient name for oats, and broma or bromus for food as the seeds were ground into The Tarahumara Indians in northern Mexico use the grains of some native Bromus species to aid fermentation in making one of their cultural beverages. Do not apply Osprey XTRA more than once per crop year. This weed has an extensive shallow root system and roots with many hairs that enable the plant to extract much of the soil water. The rough awns of downy brome can puncture the soft tissues of the mouth, nostrils and eyes of livestock; perforation of the intestines has also been reported.
