Fusariumspecies associated with stalk rot of grain sorghum in the northern grain belt of eastern Australia

Fusarium species associated with grain sorghum and mungbean in Queensland

“…The most common Fusarium species reported on sorghum in Australia has been F. moniliforme sensu lato, and since its identification in 1931 the species has been identified as the primary cause of root and stalk rot of grain sorghum in coastal areas of New South Wales and Kununurra in Western Australia, and has regularly been reported as a significant pathogen of sorghum in New South Wales and Queensland (Ryley et al, 2002, Henzell et al, 1984, Burgess et al, 1981, Trimboli & Burgess, 1982, Trimboli & Burgess, 1985, Petrovic et al, 2009). …”

“…Several Fusarium species within the chlamydosporum, dimerum, incarnatumequiseti, oxysporum, sambucinum, and solani species complexes have also been associated with sorghum (Claflin, 1986, Petrovic et al, 2013, Petrovic et al, 2009, Trimboli & Burgess, 1985, Shivas, 1989, Zummo, 1984, HyoWon et al, 2013.…”

“…(2009) detected a total of 14 Fusarium species associated with sorghum stalk rot, as listed in Table 2 (Petrovic et al, 2009). Fusarium thapsinum and F. andiyazi were the two dominant species in the study and the results suggest that their dominance and relative abundance was associated with agroclimatic areas (Petrovic et al, 2009).…”

“…Other species of Fusarium reported to colonise sorghum tissues include F. acaciamearnsii, F. boothi, F. chlamydosporum, F. compactum, F. cortaderiae, F. culmorum, F. dimerum, F. equiseti, F. graminearum, F. meridionale, F. oxysporum, F. pseudograminearum, F. sacchari, F. sambucinum, F. scirpi, F. semitectum (synonymous with F. incarnatum and F. pallidoroseum), F. solani, and F. tricinctum (Claflin, 1986, Trimboli & Burgess, 1985, Shivas, 1989, Zummo, 1984, Petrovic et al, 2009, HyoWon et al, 2013, Petrovic et al, 2013, Quazi et al, 2009, Leslie & Summerell, 2006. Recent advances in taxonomy have seen most of these species segregated within species complexes.…”

“…Since then, several studies have proven F. thapsinum to be the dominant sorghum stalk rot pathogen in most areas worldwide (Klittich et al, 1997, Leslie & Marasas, 2002. A study by Petrovic et al (2009) in two sorghum crops in eastern Australia found both F. thapsinum and F. andiyazi to be the most prevalent species in stalk rot affected plants. It is not known which Fusarium species dominate other sorghum crops in eastern Australia, and whether their prevalence changes between regions.…”
