Abstract
In spring, 1947, barley plants growing near Edinburgh, Scotland, were affected by pre-emergence and seedling blight, the bases constantly yielding Fusarium avenaceum and F. culmorum, Pathogenicity experiments in the greenhouse on six barley and three wheat varieties in inoculated sterile sand and with barley only in unsterilized soil showed F. culmorum to be a weak pathogen and F. avenaceum a strong one as determined by the effect on emergence and seedling infection. The barley reactions, in order of increasing susceptibility to F. avenaceum, were Spratt-Archer, Pioneer, Plumage-Archer, Abed Maja, and Rigel, and the wheat, Squareheads Master, Yeoman, and Holdfast. Incidence was low in acid soils (pH 4.5 to 5) but increased as the pH rose.
