Control of downy brome (Bromus tectorum
) with herbicides and perennial grass competition.
seed germination: between-population and between-year variation.
Three noxious species listed by the Idaho Department of Agriculture included Bromus tectorum
(Cheatgrass), Lepidium latifolium, and Linaria vulgaris (USDA, NRCS 2012).

For example, Evans and Young (1970) found that placing seeds of the annual Bromus tectorum
(cheatgrass) below 5 or 10 cm of herbaceous leaf litter increased fall and early spring emergence by 4- to 5-fold in a field experiment in the Great Basin Desert of western Nevada.
Correlation between molecular markers and adaptively significant genetic variation in Bromus tectorum
(Poaceae), an in breeding annual grass.
Winterfat and an invasive annual, cheatgrass (Bromus tectorum
), were significantly taller inside the exclosure and there were twice as many sagebrush individuals, indicating greater recruitment.

(2003) found that conservation tillage was less productive than moldboard plowing probably because of lack of downy brome (Bromus tectorum
L.) control in the conservation tillage systems.
Cheatgrass (Bromus tectorum
), a relative of brome, has spread throughout millions of acres of the cold Great Basin Desert.
The research at El Reno focused on bermudagrass, Cynodon dactylon, alone and with a scattering of senescent downy brome, Bromus tectorum
, and yellow bristlegrass, Setaria glauca.
Common species were broom sedge (Andropogon scoparius), weeping lovegrass (Eragrostis curvula), Downy chess (Bromus tectorum
), fescue species (Festuca spp.) and Japanese honeysuckle (Lonicera japonica).
This grows in sites at higher elevations, together with the grasses Bromus tectorum
, alkali grass (Distichlis spicata), dropseed (Sporobolus airoides), and different species of prickly pear (Opuntia).
