Downy Brome |
|
| COMMON NAME: | Downy Brome |
| SCIENTIFIC NAME: | Bromus tectorum L. |
| TYPE: | Annual Cool-season Weedy Grass |
| DESCRIPTION | |
| Germination: | September to November. |
| Reproduction: | By seeds late April to early May. |
| Stems: | Erect or spreading, slender, 6 to 24 inches high. |
| Leaves: | Blades and sheaths covered with long soft hairs. |
| Flowers/ Inflorescence: |
Rather dense panicle, soft, very drooping, often purplish. Spikelets 4- to 7-flowered. |
| Fruit: | Seed unit long and narrow and includes lemma and palea, lemma pubescent and awned (1/2 to 3/4 inch awn). |
FOUND: |
Downy brome is found in pastures, small grains, along roadsides and is a major problem in old thinning alfalfa stands. It has very poor forage quality, so it drastically reduces the value of alfalfa hay. |
CONTROL: |
In seedling stands of fall-planted alfalfa, good control is obtained with fall application of POAST PLUS or SELECT. In established stands, good control is obtained with residual herbicide like VELPAR and SINBAR (0.5 lb/A of active ingredient) applied January to February. |
