Sorghum (Sorghum bicolor) is mainly grown for stock feed in eastern Australia where significant economic losses result from diseases caused by Fusarium spp. (Petrovic et al., 2009; Kelly et al., 2017). During the 2018 sorghum growing season, 66 plants showing symptoms typical of Fusarium infection were randomly collected from three sorghum fields in Barramornie (27.08○N, 150.11°E), southern Queensland. Fusarium isolates were obtained from surface-sterilised sorghum stem or root pieces (1 cm) placed on Fusarium-selective PCNB media (Leslie & Summerell, 2008) and incubated at 23°C for five days. Ninety single-spore cultures were sub-cultured on potato dextrose agar (PDA) for molecular characterisation and 17 of these were deposited into the Queensland Plant Pathology Herbarium (BRIP, Brisbane, Australia).
