Variation in pathogenicity on potato tubers and sensitivity to thiabendazole of the dry rot fungus Fusarium avenaceum.

The majority of isolates of F. avenaceum [Gibberella avenacea] caused dry rot on potato tubers; many were as pathogenic as F. coeruleum [F. solani var. coeruleum]. Pathogenicity of G. avenacea was not related to the plant species from which the isolates originated. Tubers of potato cv. Cara were more susceptible than those of cultivars Romano or Maris Piper. Temperature (5-15 deg C) had no effect on lesion depth, but lesions tended to be slightly wider at the lowest temperature. Of 61, 2 isolates from wheat and white lupin had a moderate level of resistance to thiabendazole. The results are discussed in relation to the control of dry rot in stored potato tubers.
