Downy Brome (Bromus tectorum) Control in Winter Wheat
Weed Technology, 1988Metribuzin at 0.42 kg ai/ha and metribuzin plus terbutryn at 0.28 plus 0.67 kg/ha were applied in the fall and spring to control downy brome in winter wheat from 1981 through 1985. Downy brome control averaged 88% from the fall-applied treatments and 63% from the spring-applied treatments.

Ecological genetics of seed germination regulation in Bromus tectorum L.
Oecologia, 1999Regulation of seed germination phenology is an important aspect of the life history strategy of invading annual plant species. In the obligately selfing winter annual grass Bromus tectorum, seeds are at least conditionally dormant at dispersal in early summer and lose dormancy through dry-afterripening.

Resistance to chlortoluron in a downy brome (Bromus tectorum) biotype
Weed Science, 2006A downy brome population in a winter wheat field at Córdoba, Spain, survived use rates of chlortoluron (2.5 to 3.5 kg ai ha−1) over 2 consecutive yr, where wheat monoculture and multiple annual chlortoluron applications had been carried out. The resistant (CR) biotype showed a higher ED50value (7.4 kg ai ha−1; the concentration required for 50 ...

The Demography of Bromus Tectorum: Variation in Time and Space
The Journal of Ecology, 1983(1) Amplitude in the variation of recruitment, survivorship and fecundity was examined for the introduced annual grass Bromus tectorum in three habitat types in eastern Washington (U.S.A.) for three consecutive generations. A total of 18 143 individuals in populations varying from 364 to 5322 members per site were mapped repeatedly from emergence to ...

Cheatgrass (Bromus Tectorum) Seeds are Still Viable after Laundry Cycle
Natural Areas Journal, 2014ABSTRACT: Bromus tectorum is expanding across western North America. This spread is due to its own competitive abilities, land management practices, and unintended transport by the public as the plant's spikelets often lodge in clothing. Many assume that washing in a laundry machine makes the seeds nonviable: we decided to test this assumption.

Multitemporal spectral analysis for cheatgrass (Bromus tectorum) classification
International Journal of Remote Sensing, 2009Operational satellite remote sensing data can provide the temporal repeatability necessary to capture phenological differences among species. This study develops a multitemporal stacking method coupled with spectral analysis for extracting information from Landsat imagery to provide species-level information.
