Correlation between fusaric acid production and virulence of isolates of fusarium oxysporum that causes potato dry rot in South Africa.

The major mycotoxigenic species of fusarium and Aspergillus phytopathogens are identified in this The virulence of 12 fusarium oxysporum isolates  was determined on three potato cultivars, Late Harvest,  BP1 and Kimberley Choice. The production of fusaric acid by F. oxysporum isolates was determined to establish whether a correlation exists between fusaric acid production and virulence. Late Harvest was the most tolerant and BP1 the most susceptible cultivar.  Virulence ranking order of the F. oxysporum isolates with the different cultivars corresponded  with the mean of value of the ranking order for all three cultivars. A correlation was found between  virulence of isolates and fusaric acid production except for Late Harvest.
