Variability in the Fungus
Sattar and Hafiz (1952) have isolated about six cultural types, however, no
difference in pathogenicity was observed. Two culture types depending on the
color of mycelial growth were isolated by Inam (Annual Report, PL-480 Project,
1972-73) but no difference in virulence was observed.
