Why is Downy Brome Spreading?

0

Downy brome produces 500 lbs/acre or 550 kg/hectare of seed every year. It germinates under a variety of conditions: 5 to 40C. Although 98 per cent of the seed germinates within two years, the remaining two per cent (10 lbs/acre) can germinate up to five years later. It persists along fencelines and likes disturbed soil. Calves tend to like to lie in it, spreading the seed. It gets onto reclamation sites through the use of contaminated straw used for crimping, impure seed and equipment that hasn’t been cleaned. What Can We Do to Prevent the Spread of Downy Brome? Ask for a seed testing certificate for every seed lot of seed purchased for reclamation (prior to mixing) and ensure that it contains no downy brome. If you are using straw for crimping, use reputable growers and inspect the fields for weeds prior to harvest. On public land you must also receive clearance from the local Public Lands manager. Keep disturbances as small as possible, particularly on sandy or gravelly soils. Contr
