Abstract

Crown rot of winter cereals is a major constraint on grain
production across most growing regions in Australia, particularly where stubble retention is practiced to maintain soil structure and retain soil water. The predominant cause of this disease is infection with Fusarium pseudograminearum (Fpg), although in some southern areas Fusarium culmorum infections are also significant. These Fusarium species are able to grow saprophytically on stubble remnants over the summer and provide inoculum for crop infection in the following season. Losses due to crown rot are highest in seasons featuring a dry finish in which maturing plants experience water stress, with symptoms including basal stem browning and white heads bearing no grain.
