Competition Between Winter Wheat and Downy Brome
Weed Science, 1974Four experiments were conducted to develop controls for downy brome (Bromus tectorum L.) in winter wheat (Triticum aestivum L. ‘Gaines’). In three experiments downy brome was removed at monthly intervals from emergence to harvest. In the third and fourth experiments, hand weeded and weedy controls were compared to chemical control with R11913 (3 ...

Host range of a deleterious rhizobacterium for biological control of downy brome
Weed Science, 2001Abstract Pseudomonas fluorescens strain D7 (P. f. D7; NRRL B-18293) is a root-colonizing bacterium that inhibits downy brome (Bromus tectorum L. BROTE) growth. Before commercialization as a biological control agent, strain D7 must be tested for host plant specificity.

High Phenotypic and Molecular Variation in Downy Brome (Bromus tectorum)
Invasive Plant Science and Management, 2008Abstract The invasive grass Bromus tectorum (cheatgrass, downy brome) has extensive ecological breadth in its introduced range, and is increasing in abundance at high elevations. As a predominantly selfing species with high potential population growth rates, it is a likely candidate for having general-purpose genotypes that facilitate its invasion into

Fallow Method Affects Downy Brome Population in Winter Wheat
Journal of Production Agriculture, 1992Downy brome (Bromus tectorum L.) is a prevalent weed infesting winter wheat (Triticum aestivum L.) in the Great Plains. Long‐term field research was initiated in 1980 on a Williams loam soil (fine‐loamy, mixed Typic Argiborolls) near Sidney, MT, to determine the effect of stubble mulch (SM), minimum‐till (MT), and no‐till (NT) fallow methods on downy ...

Downy Brome Control by Soil-Active Herbicides for Revegetation of Rangelands
Weed Science, 1969Eighteen soil-active herbicides were evaluated for control of downy brome (Bromus tectorumL.) and associated broadleaf weeds during revegetation of big sagebrush (Artemisia tridentataNutt.) rangelands in Nevada and in northeastern California. We rated all herbicides in reference to a chemical-fallow program for replacement of vegetation, where seeding ...

Weed Technology, 1999
The genusBromusin the Poaceae includes 100 species of annuals, biennials, and perennials. Several species are important as forage crops while others are grown as ornamentals. It is distributed in the temperate areas and in tropical mountainous regions (Hyam and Parkhurst 1995).Bromus tectorumL., downy brome, an introduced annual, occurs throughout most

Mapping Downy Brome (Bromus tectorum) Using Multidate AVIRIS Data
Weed Science, 2008Abstract Invasive plants impose threats to both natural and managed ecosystems. Downy brome is among the most aggressive invasive weeds that has infested the shrub-steppe ecoregion of eastern Washington. Hyperspectral remote sensing has potential for early detection and for monitoring the spread of downy brome—information that is essential for ...

Downy Brome Competition and Control in Dryland Wheat1
Agronomy Journal, 1968AbstractCompetition between downy brome (Bromus tectorum) and winter wheat causes serious economic losses to growers in the Pacific northwest. On a site which received 25 cm average annual rainfall and had a light soil (very fine sandy loam) winter wheat yields were reduced 28% by fewer than 54 downy brome plants per m2 (5 plants/ft2).
