Abstract | M. phaseolina, a soilborne pathogen, causing charcoal rot in more than 500 crop species Splitting sorghum stalks will show ash grey tissue or microsclerotia, the survival structure of the fungus, giving the internal stalk tissue a peppered look Causes major sorghum stalk rotting, which can lead to plant lodging Common during seasons with prolonged hot, dry weather or when other unfavourable environmental conditions stress the plant Despite the lack of formal quantification in Australia, significant yield losses have been associated to prevailing hot dry conditions resulting to widespread high incidences of charcoal rot and subsequent lodging The present work aims to compare pathogenicity and aggressiveness of isolates, from sorghum and other hosts from the northern region, to sorghum |
