Fusarium wilt of cotton was first identified on the Darling Downs in Queensland almost 10 years ago in March 1993. This destructive disease of cotton is caused by a soil-inhabiting fungus, Fusarium oxysporum f.sp Vasinfectum (Fov), and two different strains of the causal pathogen have since been described in Australia (Kochman, 1995; Davis et al 1996; Kochman, et al. 1998). The two different genotypes (strains) identified amongst the Australian isolates of Fov corresponded to Vegetative Compatibility Groups (VCGs) 01/11 and 01/12. At present, each of these strains appears to be equally capable of causing disease in the current commercial varieties in Australia, but this may not be the case with new varieties in the future. The two Australian genotypes are distinct from all overseas strains of Fov and the other species of Fusarium examined thus far. The disease has been found in new areas every season since 1993. During the 2001/2002 season, new recordings of Fov were confirmed in the Brewarrina (NSW) district and in Pima cotton at Bourke. Pima cotton was also devastated by the disease in the trials at &quote;Cowan&quote; near Cecil Plains in Queensland. The disease was identified on more farms at Brookstead, Dalby, Goondiwindi, Toobeah, St George and Theodore in Queensland as well as Moree, Bourke, Carroll and Warren in New South Wales. No records of Fov have yet been made from the production areas of Emerald in Queensland, Tandou or Hillston in New South Wales or in Western Australia. No new strains of Fov have been identified amongst the specimens received to date.
