Practical Information

Forage Value
Downy brome offers fairly good forage value prior to inflorescence emergence but has practically no value after that time. Songbirds and turkeys consume the seeds.

Additional Notes

Comments

Tufted. An aggressive, cool season weed. The awns can injure the eyes and mouths of grazing livestock and contaminate fleece.
