Abstract
Summary: Leaf scald (caused by Rhynchosporium secalis) is one of the most
economically important diseases of barley. Data were collected from three seasons
of trials using two susceptible winter barley cultivars (Sumo and Saffron) and two
resistant cultivars (Flagon and Manitou). Levels of R. secalis DNA were
quantified from several growth stages (GS) throughout the growing season and
visual symptoms assessed. Results demonstrate that the pathogen was able to
colonise and sporulate extensively on apparently healthy leaves, and spread to
grain without symptoms being seen in the crop. This raises questions about how
the fungus interacts with the plant, what triggers lesions to develop and the role of
asymptomatic infection in pathogen spread, plant defence and crop yield.
