Abstract
The progression of common root-rot lesions on subcrown internodes of Neepawa wheat and Bonanza barley plants inoculated 14, 26, 38 and 50 days after seeding was measured in growth chamber tests. Both in wheat and barley, lesion development was more rapid in older than in younger plants. Variables such as mean daily rates of linear progression of lesions, disease ratings, and proportion of plants becoming severely diseased were higher in older than in younger plants. The possible stress resulting from the removal of the crown roots on more rapid disease development in older than in younger plants is discussed.
