USDA is an equal opportunity provider and employer. }else{ may be an effective control method for smooth brome. If left unchecked, this may not meet the approved practice cover and may result in noncompliance. Smooth brome is the most widely used of the cultivated bromegrasses. Justin Haag has served the Commission as a public information officer in the Panhandle since 2013. During the winter, the applied chemical has a direct path to the source of the problem, the root system. Clay particles in the air absorb chemicals and reduce efficiency. Native grasses are dormant at this time while cool-season grasses are still actively growing. In especially For example, Teel (1956), Reynolds and Smith (1962), and Eastin et al. dom_i.query(this).css("margin","0"); if(imgMarginLeft.indexOf("px") > 0){ About Justin Haag . Smooth brome is often planted as a forage species that can escape to forests, prairies, fields, lawns, roadsides, railroad right-of-ways, and lightly disturbed areas. Spray for brome along field edges, waterways, and along the tops of the old terraces. Treatments included five herbicide combinations, a imgMarginRight = imgMarginRight.replace("px",""); 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. If you have a Conservation Reserve Program (CRP) contract that requires a native grass cover and you have an invasion of brome grass, this defeats the wildlife benefits. Smooth brome is a grass that was introduced into the U.S. from Europe in the late 1800s and was widely established due to its resistance to depression-era droughts. : dom_i.query(this).css("margin-bottom").trim(); 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. var imgTitle = dom_i.query(this).attr("title") == undefined ?

Smooth brome and Kentucky bluegrass are introduced cool-season perennial grasses known to invade grasslands throughout North America. This weakens the plant, and creates root space and access to sunlight and moisture for your surrounding native warm season grasses, forbs and legumes. Low intensity head fire burning through smooth brome. PLANTS Characteristics Data Fields and Definitions for more than 100 Characteristics This article is also available in Microsoft Word format. Smooth brome will be one of the first grasses greening up early in the spring. is a cool-season, Eurasian grass introduced to the west coast of North America in the 1880s (Archer and Branch 1953). A controlled burn on your CRP field at the right time will increase your chances of eliminating brome grass as well as prescribed grazing. } 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. Try to apply herbicides on a mostly sunny day and never when overcast. This study occurred over a three year period at the Agricultural Research and Development Center located near Mead, Nebraska from 2011 – 2013. Caution should At a second site, smooth brome densities were reduced by glyphosate but not by burn treatments. At one site, changes in the density of smooth brome were affected by the interacting effects of burn treatments and glyphosate application. Fires also remove the build-up of dead vegetation, encourage new grass growth and control non-prairie plants like Kentucky bluegrass and smooth brome. Brome is a cool-season grass, which means that it is actively growing at fairly cool temperatures in the spring. PLANT RESPONSE TO FIRE: Pumpelly's brome likely sprouts from rhizomes after top-kill by fire. 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. Smooth brome (Bromus inermis) is an introduced, cool-season perennial, sod-forming grass that has been shown to invade both native cool-and warm-season grasslands throughout North America. INTRODUCTION Smooth brome (Bromus inermis Leyss.) It can also imperil herptiles and insects as well as early migrating grassland birds, such as the American woodcock. Timing was also key in controlling smooth brome (Bromus inermis ) and encouraging the growth of native grasses in Nebraska and Minnesota ( Willson & Stubbendieck 2000). dom_i.query(document).ready(function(){ The best time of day to spray is from 9 a.m.�6 p.m., never at or near dark. Continually monitor these areas because one treatment will not completely eradicate the brome grass. Fire doesn’t kill the smooth brome and can damage early spring forbs and native cool season grasses. Atrazine was the only treatment that significantly reduced smooth brome tiller density (-77% 1990; -70% 1991) as compared to unburned controls. 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. } Willson and Stubbendieck (2000) recommend burning in early spring at the four or five leaf stage of smooth brome. Although less invasive than Kentucky bluegrass, with which it often occurs and is managed, it is also less responsive to management. / Smooth Brome Grass - Control in CRP Fields, by Tyson Seirer, Kansas Representative You may also use a surfactant or ammonium sulfate to increase glyphosate activity. Fire may control the grass from spreading, if burned in late spring, but will not kill the rhizomes. var dom_i = {}; Natural Areas Journal, v. 15, no. Burning had no significant effect on stem density of smooth brome. There was, however, a trend for greater reduction of smooth brome with glyphosate application in the spring burn (98%) than in the fall burn (40%) and unburned (56%) plots (SE +-15.5). Members of the Buffalo Fire Use Module on the ignition team. if(imgTitle != ''){ Studies show that wild mammals and birds recognize fire and nearly all escape the flames. Cool-season grasses are the last grasses to become dormant in the fall. A dormant burn only followed by cattle grazing of regrowth can dramatically reduce smooth brome grass. }else{ Smooth brome will be one of the first grasses greening up early in the spring. Will recedars resprout? if (imgTitle != '') { Click on an acronym to view each weed list, or click here for a composite list of Weeds of the U.S. Brome will be stimulated if it is burned during its dormant period. 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. var imgMarginRight = dom_i.query(this).css("margin-right") == undefined ? The native grasses and other prairie plants will respond well to treatment since it will weaken the cool-competitors. 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. It is a strong competitor post-fire. 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. imgWidth = imgWidth.replace("px",""); if(imgAlt != 'Broken Link' && imgAlt != '' && imgAlt != 'offsite link image'){ imgMarginTop = imgMarginTop.replace("px",""); 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. Remove leaf matter prior to the treatment to maximize results. : dom_i.query(this).attr("title").trim(); Burning and mowing were evaluated in 1989-1991 at Pipestone National Monument, Minnesota, as alternatives to atrazine to suppress smooth brome (Bromus inermis Leyss.) However, since the rhizomes are protected by soil, most fires probably do not harm the rhizomes. Small mammals go underground while larger ones move away temporarily or jump unharmed across the fire line. Can I burn in the summer? 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. if(imgMarginTop.indexOf("px") > 0){ var imgMarginBottom = dom_i.query(this).css("margin-bottom") == undefined ? '' if(imgWidth.indexOf("px") > 0){ The proportion of seedlings emerging was lower for native graminoids (33 vs 41%, SE +-2) and greater for native forbs (56 vs 48%, KSE +-3) in brome as compared to fescue plots. dom.query('img').each(function(){ After putting out a seed head in early summer, brome will become dormant. Interpretive Summary: Fire can reduce invasive grasses, such as Kentucky bluegrass and smooth bromegrass without hurting cool-season native grasses while enhancing warm-season native grasses. The E.V. var count = 1; }); These areas may not have been seeded well enough to get established and are likely spots for brome to creep into your fields. 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. It will be damaged during the growing period once most root resources have been invested into the growth of the plant. imgMarginBottom = imgMarginBottom.replace("px",""); Control of smooth brome and Kentucky bluegrass using fire and fire plus chemical in the northern Great Plains.

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. var imgFloat = dom_i.query(this).css("float") == undefined ? 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. Brome grows well in poor soils and is found in odd areas where native grass has trouble getting started. 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. Look for the W or M shape in the leaf. } Smooth brome and Kentucky bluegrass are introduced cool-season perennial grasses known to invade grasslands throughout North America. Brome grass also out competes other native grasses and broadleaf plants. dom_i.query(this).css("float","none"); That is expected to reduce the fire’s intensity. Dormant season burns combined with grazing help focus grazing pressure.

"); Presented at the Invasive Species Workshop on April 5-7, 2005, Bismarck, ND. subsp. Reduce the cover of non-native grasses, specifically smooth brome (Bromus inermis). Look for low wind and dust conditions and less than 80 percent humidity. Life History/Ecology: Smooth brome is a cool season, perennial grass that can spread by seed and Smooth brome, a cool-season grass, is often found mixed with native warm-season grasses. Location of the Peninsula prescribed fire. It has been cultivated in the United States since the early 1880s. Pheasants Forever/Quail Forever. } This research study examined feeding ethanol co-products mixed with low-quality forage to cow-calf pairs on smooth brome pasture to replace grazed forage. 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). Summer and fall burns, if used in conjunction with grazing, can set back smooth brome, increase diversity in grasslands and improve habitat for wildlife. 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. This non-native grass is dense and lets very little new growth develop. 300 : dom_i.query(this).css("width").trim(); Smooth brome is a cool season exotic that is especially troublesome in disturbed portions of old pastures in the tallgrass and mixed prairie regions. Warm-season grasses are dormant and cool-season grasses are actively growing.

Timing is everything if using fire to control brome. } Used for pasture, forage, disturbed sites. dom_i.query(this).attr("title",imgAlt); When invasive tree sites are burned, native plant species composition increases as the trees die off, creating a more sustainable, properly functioning ecosystem. Smooth brome (Bromus inermis Leyss. } }) CRP rules and regulations must be followed for any grazing activities. 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. Fire is an essential part of restoring a prairie. 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 Does fire help control smooth brome? An engine patrols the fire perimeter. Repeated defoliation throughout the spring season will greatly weaken this brome, allowing other plants to encroach upon its "territory". 2, p. 148-156. However, we brought in cattle to knock back the strong growth of those species. 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.
