Abstract
Wirrega blotch caused by Drechslera wirreganensis has been found in barley, wheat, barley grass, brome grass, ryegrass and annual veldtgrass at several sites in South Australia and Western Australia. Variation in barley cultivars for resistance to the pathogen was identified in two field trials and yield losses of 13–36% were estimated in the susceptible cultivar skiff.
