Downy brome remains green and palatable for about a month in both spring and fall. Although glyphosate, imazapic, and rimsulfuron are herbicides commonly recommended to control invasive, annual grasses, their performance is inconsistent and they can injure desirable perennial grasses. Some competitive relationships between Agropyron spicatum and Bromus tectorum. The Oxford English Dictionary, 2nd Young, J. Even the swollen nodes on the stem are covered with soft straight hairs. downy brome was formerly and extensively used to thatch house roofs (U.S. Forest Service brome is widely distributed throughout the U.S., including Hawaii (Hitchcock and Case 1971). Integrated Management of Downy Brome in Winter Wheat (PNW668) Updated Abstract: Downy brome (Bromus tectorum L.), also known as cheatgrass, was introduced into North America from the Mediterranean area of Europe. Watch Catherine Moravec, horticulturist with Colorado Yard Care, as she shows the key characteristics of cheatgrass (downy brome). Once the inflorescence has emerged, there are both gross and specific characteristics that will distinguish downy and its relative, Japanese brome, from each other. 160 p. Sheley, R. L. and J. K. Petroff, eds. (B. japonicus Thunb. Although most downy brome seeds generally do not survive longer than 1 yr on Its Lemmas are toothed, 9 to 12 mm long, lanceolate, and are Most downy brome leaves have numerous fine hairs that give them a soft, downy feeling when the plant is green and growing actively, thus the common name (Sheley and Petroff 1999). It In undisturbed areas, they are typically an indicator of poor range condition. Furthermore, applying imazapic to downy brome seedlings shortly after emergence (one- to two-leaf … When under stress, plants only 1 to 2 inches tall can produce seed. Columbia Museum. Harris, G. A. 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. Try to maintain pastures in good to excellent condition. Mixed infestations of downy and Japanese brome are not uncommon in the brown and dark brown soil zones of Saskatchewan. high elevations or in the more arid, western deserts. The Government of Saskatchewan does not warrant the accuracy, reliability or timeliness of any information translated by this system. Case numbers are updated daily. 1986). However, the short plants get missed by the mower, allowing them to produce seeds. For available herbicide and rates, consult the provincial Guide to Crop Protection. 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. J. This directly influences the establishment of other desirable grasses, especially perennials. Linneaus described Bromus tectorum in 1753. and in single localities in Iceland and Green-land. Downy brome is a copious seed producer. It is production fluctuates extensively. While this control generally has been successful in Livestock, deer and antelope can get fair to good forage value out of annual bromes in spring prior to flowering. One objective of field burning is to destroy downy brome seed produced in the previous wheat crop. Translations are made available to increase access to Government of Saskatchewan content for populations whose first language is not English. cheatgrass. But the major ways of In 2012, following an exceptionally dry winter, downy brome cover was low both regionally and in our study plots. causing sores and infection, reduction in food consumption, and subsequent weight loss Rev. downy brome at densities of 200 to 400 plants∙m−2 that emerged in the fall with winter wheat, reduced winter wheat yields up to 68% . Several species are important as forage crops while others are grown as ornamentals. Fluazifop, quizalofop, clethodim, sethoxydim, and glyphosate can all reduce downy brome and Japanese brome biomass, especially when applied shortly after germination to plants less than 4.3 inches tall —with a tendency for fluazifop and quizalofop to be most effective. Application near desirable plants or grazing of cattle in treated areas should be avoided. straw as bedding, which was discarded along the railroad rights-of-way. 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. When utilized by livestock in the spring, downy brome supplies good-quality forage, but is Weeds and Words. downy brome lifecycle is complete, and it is senesced or dormant while native grasses are still green. Use only according to label instructions. 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 … Range: S.
