Make your post-emergence herbicide application when downy brome is young and actively growing. More information can be found in the PNW Weed Management Handbook. Downy brome seed‐to‐straw ratios were indicative of a tremendous yield potential. A number of pages on the Government of Saskatchewan's website have been professionally translated in French. Downy brome cover varied dramatically by year (P < 0.0001). Apply 5 oz/acre of Rejuvra herbicide at a minimum of 5 gallons per acre by air; for ground application, use spray volumes of 20-30 GPA total spray mix (apply up to 7 oz/acre on areas that are not grazed by livestock) For good first-year control, Rejuvra must be applied prior to germination of the target weeds Downy brome occurs in all Canadian Provinces and Zone-3: April-May Zone-4: April Zone-5: March Zone-6: March Zone-7: March.

Seeds are at least conditionally dormant at dispersal in early summer and lose dormancy through dry after-ripening. Historic and current uses During the 19th century, downy brome was sown as a forage but only occasionally (Mack 1981). The caryopses were incorporated into the surface soil by raking. Branches are The life cycle of this grass makes it competitive with winter wheat in the PNW. easily, has a shallow dense root system, and grows rapidly, it adds large amounts of organic However, it grows on many poorer sites where more nutritional forage plants do not occur (U.S. Initial infestations were commonly found near railroads and wheat fields. Habitats: Roadsides and waste places, also in thatched roofs in Eastern N. America[43]. In annual cropland, fall harrowing is another method to stimulate the germination of seed in the fall, followed by spring tillage or glyphosate to control spring seedlings and over-wintered plants. The leaves are from 4 to 16 cm long, 2 to 4 mm wide, light green, and pubescent. Downy and Japanese brome plants have no historical uses. Burning of wheat crop residue after harvest has commonly been used as a method of controlling downy brome. 1995). Since its life cycle terminates relatively early in the season, uncontrolled downy brome is a fire hazard and is extremely flammable, allowing fires to kindle and spread rapidly. It perpetrates itself Try to maintain pastures in good to excellent condition. Because down brome establishes Downy (feathery; fluffy) was first used as specific names for plants such as … layers. Synonyms. Distribution. Pioneer farmers felt that were being cheated in wheat yields by the weed and labeled it Oxford, UK: Oxford University Press. Several species are important as forage crops while others are grown as ornamentals. Downy brome is a common winter annual weed in-festing alfalfa in many parts of the U.S. Paraquat, pron-amide, simazine (6-chloro-N,N'-diethyl-1,3,5-trizine-2,4-diamine), and terbacil have been used to control downy brome selectively in established alfalfa (Kapusta … If near universal agreement is found on the scientific name, chaos prevails on common names. Washington, DC: U.S. Government Printing Office. Moldboard plowing of winter wheat stubble in the fall after harvest to deeply bury downy brome seed traditionally has been used as the primary con-trol for downy brome in in-fested winter wheat crop rotations. The jagged ligule is one to three mm (1/8 to 1/4 in.) It is formulated as a water-soluble liquid. Downy brome (Bromus tectorum) is a winter annual grass introduced into the U.S. from Europe in the 1800s through a contaminated shipment of grain. (Simpson and Weiner 1989). 1964. soft, and drooping, and is often pale green with a purple tinge. Principal component analyses of vegetation cover indicate a shift from plant communities characterized by high bare soil and forbs immediately postfire to communities with increasing downy brome cover with time after fire. Responses of downy brome to added nitrogen and water were evaluated using intact soil cores obtained from an old field. In its original home in Old World humid climates, produce 5,000 seeds (Young et al. Vigorous stands of grasses or grass-legume combinations are highly competitive with downy brome and other annual weeds. in ships sailing from Eurasia into North America was one of the original carriers of its seeds.

The translation should not be considered exact, and may include incorrect or offensive language. Its successful expansion in the western U.S. ultimately translated into downy brome providing much of the spring-utilized forage in the Pacific Northwest and the Intermountain regions by the late 1940s (Hull and Pechanec 1947). 1989). In the field, imazapic reduced downy brome cover by 20% and nontarget forb cover by 25% and altered plant community composition the first year after treatment.

Grazing: Downy brome has become an important early, but very short season forage in the intermoun-tain west and grazing can prevent seed production if plants are grazed early. un-grazed stands of it produce a litter layer which is very effective in conserving soil by During ripening, downy brome plants turn purple and then brown as they mature, but the leaves preventing raindrop erosion, promoting water infiltration, and preventing Integrated Management of Feral Rye in Winter Wheat (PNW660) Updated Abstract: Feral rye (Secale cereale L.), … Downy brome is best controlled in wheat using integrated weed management (IWM). Downy brome is a major weed problem in winter wheat. They are actually a major forage source in part of the north western United States, supplying the bulk of early spring forage for all livestock classes. 1937. ed., Volume 2. Protein content drops to about 3 percent as plants mature, and long slender awns on the seed head can limit feed intake by irritating and puncturing the soft tissues in-side the mouth of grazing ani-mals. 1987. Prevent the return of downy brome by establishing a good lawn maintenance routine (mowing regularly at the right height, watering and fertilizer) Downy brome biotypes resistant to all of the Group 2 (ALS inhibitors) herbicides have been identified in Washington. Eliminate Seed Sources: 1. Downy brome is a significant weed throughout North America, particular in alfalfa (Medicago One objective of field burning is to destroy downy brome seed produced in the previous wheat crop.

With the exception of Alabama, Georgia, South Carolina, and Florida, downy Bromus mango was historically cultivated in Chile and Argentina by indigenous peoples, who used it both as fodder and food. 1995. brome seeds usually do not remain viable for longer than 1 yr (Hulbert 1955). Top of page In Russia, Anisantha tectorum (L.) Nevski is used by some authors as the taxon for this species, but Bromus tectorum L. is universally used in publications in English (Kostivkovsky and Young, 2000). Identification Downy brome is a winter annual grass that ranges from 12 to 24 inches in height at maturity. The inflorescence is a many branched panicle which droops to one side. Mixed infestations of downy and Japanese brome are not uncommon in the brown and dark brown soil zones of Saskatchewan. Downy brome biotypes resistant to glyphosate have also been identified. Bromus tectorum and refers to its abundance as a weed in areas where cereal grains are grown. overwintering in a semidormant state and completing their life cycle the next spring. But downy brome palatability decreases rapidly and heavy spring grazing can also suppress desirable, perennial forage, allowing downy brome to proliferate. Invasive plants should never be considered as for-age. The Oxford English Dictionary, 2nd Young, J. Range infested with annual brome species experiences a drastic shortening of the normal prairie fire cycle, resulting in a change of species composition that favours the persistence of annual bromes and other fire tolerant species.
