These herbicides also reduced seed-producing stems of downy brome by more than 65%, which should reduce the amount of seed returned to the seedbank. Cheatgrass, also known as downy brome (Bromus tectorum), and its equally obnoxious cousin Japanese brome (Bromus japonicus) are annuals that usually germinate in the fall and overwinter as seedlings. Pyroxasulfone Is Effective for Management of Bromus spp. … All other treatments provided between 50% and 70% control of downy brome, with the exception of fall-applied thiencarbazone, which provided less than 50% control.
