Abstract

Historical records report Fusarium moniliforme sensu lato as the pathogen responsible for Fusarium diseases of sorghum, however recent phylogenetic analyses has separated this complex into more than 25 species. During this study, surveys were undertaken in three major sorghum producing regions in eastern Australia to assess the diversity and frequency of Fusarium species associated with stalk rot and head blight infected plants. A total of 523 isolates were collected from northern New South Wales, southern Queensland, and central Queensland. Nine Fusarium species were isolated from diseased plants. Pathogenicity tests confirmed F. andiyazi and F. thapsinum were the dominant stalk rot pathogens, whilst F. thapsinum and species within the Fusarium incarnatum-F. equiseti species complex were most frequently associated with head blight.
