In the fall consider applying glyphoshate at a higher rate (at least 64 ounces per acre) because the more leaf contact applied through the foliage of the native grass results in better success. Brome grass also out competes other native grasses and broadleaf plants. smooth brome This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. Komarek Fire Ecology Database is the intellectual property of the Tall Timbers Research Station and Land Conservancy. Abstract. [CDATA[ Brome is best controlled early before it takes over the entire field. Many bunch grasses burn quickly and are less susceptible to fire damage. This tactic is thought to work because smooth brome is a cool season grass that begins its growth cycle and sets seeds before native warm season grasses (i.e., C4). It has been cultivated in the United States since the early 1880s. Remove leaf matter prior to the treatment to maximize results. Smooth brome will be one of the first grasses greening up early in the spring. (1964) Defoliation stimulates growth and increases the effectiveness of herbicide applications and can be achieved by burning, mowing, haying, or grazing prior to the chemical treatment. Continually monitor these areas because one treatment will not completely eradicate the brome grass. if (imgTitle != '') { If left unchecked, this may not meet the approved practice cover and may result in noncompliance. An engine patrols the fire perimeter. Glyphosate reduced the density of native graminoids 91% (SE +-10.0), but plains rough fescue and native forbs were not affected. The optimal timing for control of smooth brome by burning appears to be in boot stage, which may be as early as mid-April in the central Great Plains or in the northern plains. The office is located at your USDA Service Center (listed in the telephone book under United States Government or on the internet at offices.usda.gov). Prior to the native prairie grasses that have been established, this preserve was covered with a short European grass called smooth brome, which was planted when the land was used for grazing and farming. IMMEDIATE FIRE EFFECT ON PLANT: Aboveground portions of Pumpelly's brome are probably killed by fire during the growing season. Fire can reduce invasive grasses, such as Kentucky bluegrass and smooth bromegrass without hurting cool-season native grasses while enhancing warm-season native grasses. } Caution should Location of the Peninsula prescribed fire. Try to apply herbicides on a mostly sunny day and never when overcast. : dom_i.query(this).css("margin-bottom").trim(); Abstract reproduced by permission. Smooth brome (Bromus inermis Leyss. As an alternative to atrazine, mowing or prescribed fire has been suggested as a means to suppress smooth brome when applied at a critical growth stage. Does fire help control smooth brome? var imgMarginTop = dom_i.query(this).css("margin-top") == undefined ? Smooth bromegrass was widely used in the upper half of North America during the late 19th and early 20th centuries, with distinguishable northern and southern varieties. However, repeated mowing is usually necessary to deplete the rhizome system. During the winter, the applied chemical has a direct path to the source of the problem, the root system. This study occurred over a three year period at the Agricultural Research and Development Center located near Mead, Nebraska from 2011 – 2013. Willson and Stubbendieck (2000) recommend burning in early spring at the four or five leaf stage of smooth brome. These studies indicate that excellent control of smooth brome can be achieved with spring burning followed by wick application of glyphosate, however, native species were also reudced by glyphosate. Let us help answer any burning questions related to prescribed fire. The number of green leaves per tiller is an easily observed indicator Of smooth brome susceptibility to fire. Tall Timbers Research Station and Land Conservancy. Burns and other disturbances must not take place during the nesting season. Used for pasture, forage, disturbed sites. } Will recedars resprout? // 0){ 300 : dom_i.query(this).css("width").trim(); The best time of day to spray is from 9 a.m.�6 p.m., never at or near dark. : dom_i.query(this).attr("title").trim(); Timing prescribed burns so that they occurred at the time of tiller (aboveground lateral stem) elongation, yielded an immediate and persistent reduction in both tiller density and This non-native grass is dense and lets very little new growth develop. Spray for brome along field edges, waterways, and along the tops of the old terraces. Native grasses are dormant at this time while cool-season grasses are still actively growing. }else{ In many cases if native grasses are present on greater than 20 percent of the area with proper management, the native grass will reestablish and begin to flourish within time without needing to be reseeded. Burning and mowing were evaluated in 1989-1991 at Pipestone National Monument, Minnesota, as alternatives to atrazine to suppress smooth brome (Bromus inermis Leyss.) Always follow label guidelines when mixing chemicals. dom.query(this).attr("title",title); imgMarginBottom = imgMarginBottom.replace("px",""); After putting out a seed head in early summer, brome will become dormant. : dom_i.query(this).attr("alt").trim(); var dom_i = {}; dom_i.query('.img_'+count).wrapAll(""); Burning had no significant effect on stem density of smooth brome. It will green up again in the fall as the temperature begins to cool down. Review your contract with staff at your local U. S.

Life History/Ecology: Smooth brome is a cool season, perennial grass that can spread by seed and PLANTS Characteristics Data Fields and Definitions for more than 100 Characteristics var count = 1; 2, p. 148-156. At one site, changes in the density of smooth brome were affected by the interacting effects of burn treatments and glyphosate application. dom_i.query(document).ready(function(){ “Smooth brome’s tolerance to grazing is generally rated as high … On tallgrass prairie, it is usually found in areas with history of overgrazing and/or fire exclusion … Severe grazing converted the area to smooth brome, timothy (Phleum pretense), and Kentucky bluegrass (Poa pratensis)” (Howard 1996). More information is also available on the Kansas Web site at www.ks.nrcs.usda.gov. / Smooth Brome Grass - Control in CRP Fields, by Tyson Seirer, Kansas Representative imgMarginLeft = imgMarginLeft.replace("px",""); dom_i.query(this).attr("title",imgAlt); After putting out a seed head in early summer, brome will become dormant. We (1) compared richness and density of plant species in brome and fescue stands that were unburned or burned in spring or fall; (2) determined the effects of wick application of a 33% glyphosate solution, applied when smooth brome was in the boot stage, on the desity of brome and native flora in unburned plots and plots burned in spring or fall, and (3) determined the composition of the seedbank for its potential contribution to natural revegetation following the control of smooth brome. Smooth Brome Grass - Control in CRP Fields (DOC; 351 KB), NRCS Home | USDA.gov | Site Map | Civil Rights | FOIA | Plain Writing | Accessibility Statement, Policy and Links| Non-Discrimination Statement | Information Quality | USA.gov | WhiteHouse.gov For example, smooth brome can be reduced with fire if burning occurs at the tiller elongation stage (typically the 5 leaf stage) but fire increases smooth brome at other times of the year. dom.query(this).attr("alt") : dom.query(this).attr("title").trim(); Apply herbicide to control brome grass chemically in the fall after a killing freeze (27º F or colder for three consecutive hours or more) for best results. }else{ The best time to burn is when enough dry fuel is present to carry a fire and after the stand has greened up 4 to 10 inches tall. Fire doesn’t kill the smooth brome and can damage early spring forbs and native cool season grasses. Interpretive Summary: Reduce the cover of non-native grasses, specifically smooth brome (Bromus inermis). Clay particles in the air absorb chemicals and reduce efficiency. However, since the rhizomes are protected by soil, most fires probably do not harm the rhizomes. However, timely burning of a few invasive biennial broadleaves (e.g., sweetclover and garlic mustard), perennial grasses (e.g., bluegrasses and smooth brome), and woody species (e.g., brooms and Chinese tallow tree) also has been successful. This bibliographic record was either created or modified by the Tall Timbers Research Station and Land Conservancy and is provided without charge to promote research and education in Fire Ecology. Members of the Buffalo Fire Use Module on the ignition team. A dormant burn only followed by cattle grazing of regrowth can dramatically reduce smooth brome grass. Smooth brome and Kentucky bluegrass are introduced cool-season perennial grasses known to invade grasslands throughout North America. } Justin Haag has served the Commission as a public information officer in the Panhandle since 2013. ), an introduced perennial grass is an aggressive invader of prairie dominated by plains rough fescue (Festuca altaica Trin. imgMarginTop = imgMarginTop.replace("px",""); var title = dom.query(this).attr("title") == undefined ? Small mammals go underground while larger ones move away temporarily or jump unharmed across the fire line. dom_i.query(this).after("

"); Smooth brome will be one of the first grasses greening up early in the spring. Timing is everything if using fire to control brome. Applying glyphosate within 10 days after the frost is ideal, because the grass is beginning to pull all the moisture and nutrients in the leaves down into the root system to store energy and water during the dormant period. } imgMarginRight = imgMarginRight.replace("px",""); Can I burn in the summer? The number of seeds of native species in the soils in smooth brome stands approximates that in stands of plains rough fescue, suggesting that there is an adequate seedbank for natural recovery of vegetation following control of smooth brome. may be an effective control method for smooth brome. Brome will be stimulated if it is burned during its dormant period. It is a strong competitor post-fire. This article is also available in Microsoft Word format. Fire can reduce invasive grasses, such as Kentucky bluegrass and smooth bromegrass, without hurting cool-season native grasses and enhancing warm-season native grasses at the same time. You will not hurt the native grass during this period. It will green up again in the fall as the temperature begins to cool down. var imgTitle = dom_i.query(this).attr("title") == undefined ? '' Treatments included five herbicide combinations, a if(imgWidth.indexOf("px") > 0){ This is the time to spray. }); These areas may not have been seeded well enough to get established and are likely spots for brome to creep into your fields. } Smooth brome, a cool-season grass, is often found mixed with native warm-season grasses. dom_i.query(this).addClass('img_'+count); var imgWidth = dom_i.query(this).css("width") == undefined ? The total number of seedlings emerging from the seedbank was similar in brome and fescue plots, averaging 1794/m2 and 2078/m2 (SE+-252), respectively. 10 : dom_i.query(this).css("margin-top").trim(); Click here to see the Prescribed Fire Monitoring Report. Species richness was generally slightly greater in fescue than in brome plots. /*dom.query(document).ready(function(){ Further information Email: naa@natareas.org. Glyphosate eliminated brome in the spring burn plots and reduced densities 76 and 50% (SE+-6.4) in the fall burn and unburned plots respectively. Be sure all CRP rules and regulations are followed. Cow grazing smooth brome in a recently-burned restored prairie. is a cool-season, Eurasian grass introduced to the west coast of North America in the 1880s (Archer and Branch 1953). At a second site, smooth brome densities were reduced by glyphosate but not by burn treatments. "none" : dom_i.query(this).css("float").trim(); Dormant season burns combined with grazing help focus grazing pressure. Look for the W or M shape in the leaf. Brome is a cool-season grass, which means that it is actively growing at fairly cool temperatures in the spring. This aggressive nature turns the grass stand into a monoculture and discourages the establishment of wildlife-friendly plants that will attract bugs and insects and consequently feed for young birds. Smooth bromegrass (Bromus inermis) is a cool-season grass introduced into the United States from Hungary in 1884. Follow us on Twitter @NRCS_Kansas. The native grasses and other prairie plants will respond well to treatment since it will weaken the cool-competitors. if(imgTitle != ''){ : dom_i.query(this).css("margin-left").trim(); }) Optimum temperature for cool-season grass growth is 65-75° F, optimum temperature for warm-season grass growth is 85-95° F. Brome forms a thick matt of grass at ground level making it difficult for young grassland birds to move around in search of food while in early stages of development when mobility is key to survival. Prescribed Burning A timely prescribed burn in late spring (April 15-May 15) can remove the initial smooth brome growth forcing the plant to pull energy from its root reserves. For more information about CRP or natural resources conservation, call or stop by your local Natural Resources Conservation Service (NRCS) office or conservation district office. CRP rules and regulations must be followed for any grazing activities. //dom_i.query(imgDiv).append(""); During the fall of 2005 and spring of 2006, we implemented a restoration study at six native prairie sites in eastern South Dakota that have been invaded by smooth brome and Kentucky bluegrass. Also, never spray right before a rain. The prominent native grasses of Kansas, like big bluestem and Indian grass, are warm-season grasses and begin to grow much later in the spring and even early summer. } Warm-season grasses are dormant and cool-season grasses are actively growing. Click on an acronym to view each weed list, or click here for a composite list of Weeds of the U.S. Fire may control the grass from spreading, if burned in late spring, but will not kill the rhizomes.
