Popis: Control of topgrowth of 10-cm-tall Canada thistle (Cirsium arvense L. Scop.) was excellent, and barley (Hordeum vulgare L. ’Gait’) yields were increased when 3,6-dichloropicolinic acid was applied at rates of 0.2 kg/ha and higher. No injury to barley cvs. Gait and Klondike was evident with herbicide rates of 0.1–0.9 kg/ha applied at the three-leaf, six-leaf and boot stages and yields were not adversely affected.Key words: Canada thistle, barley tolerance, 3,6-dichloropicolinic acid
