The incidence and severity of Rhynchosporium secalis infections were assessed in a large population of Hordeum leporinum. Transects were set out in four directions from five trees to determine the effect of shading. Under the tree canopy 60.3% of H. leporinum plants were infected while only 11.2% were infected away from the canopy. Disease severity, on those plants which were infected, was higher under the canopy (mean 12.4% and 13.0% leaf area diseased for the flag and first leaves… CONTINUE READING
