In 2007, an herbicidal control study was initiated on rangeland infested with ventenata (Ventenata dubia (Leers) Coss & Durieu) near Anatone, Washington. Two rates of imazapic were applied in the early spring and fall of 2007, with the first application demonstrating considerably better control than that of the second. This publication discusses the outcome.
