List C <br /> .rowny brome / Cheatgrass - Bromus tectorum <br /> This annual or winter annual, native to the Mediterranean region, ranges in <br /> height from 2" to 36". Each plant contains multiple erect stems with multi- <br /> branched inflorescences at their tips, which are slender, dense and usually <br /> drooping; at maturity they appear greenish-purple. Cheatgrass reproduces <br /> solely by seed, which is viable for 2 to 5 years. The root system is fibrous and <br /> fleshy. When mature Cheatgrass dries it becomes a major fire hazard, which <br /> has increased rangeland fire frequency from once every 60-110 years to once <br /> every 3-5 years. Habitats include roadsides, waste areas, misused pastures, <br /> rangelands, cultivated fields, and eroded sites. Grazing animals will forage on <br /> the green plants, but the sharp seeds on the dried plants can injure grazing <br /> animals, getting caught in the mouth, nose and eyes. <br /> Identification: <br /> 'nflorescences: Slender, dense, 3/8" to 3/4" long, usually drooping. <br /> Greenish-purple at maturity. <br /> • Leaves: Flat blades, densely covered with soft hairs. <br /> • Stems: Multiple erect stems, 2" to 36" tall. <br /> Control Methods: <br /> Biological: No insect biological control currently available. <br /> Mechanical: Tillage, mowing and grazing help reduce established <br /> plant populations. The key to effective control is to prevent <br /> seed production and/or spread. <br /> Chemical: <br /> Imazapic: Apply in fall prior to a hard freeze and/or in early spring. <br /> *Glyphosate: Apply in fall or early spring. <br /> * Non-selective chemical, will kill all vegetation it contacts <br /> 58 <br />
