Abstract:
Seeds of five sorghum cultivars were tested for seedborne
fungi. The following fungi were detected, these were
Cuvularia lunata, C. harvey, C. pallesens, C. cymbogonis,
Drechslera spicifer, D. bicolor, Fusarium moniliforme,
Alternaria alternata, Aspergillus niger, A. flavus, A. terreus,
Cladosporium spp and Rhizopus sp. The internationally
accepted techniques of seed testing were employed. The
fungus Curvularia lunata was encountered in high
percentage. Hence physiological studies as well as
pathogenic propensities for this fungus were investigated.
The optimum temperature for the growth of this fungus was
28ºC. The suitable medium for growth of C. lunata was
found to be potatoes sucrose agar. The pathogenic
propensities revealed that the fungus causes leaf spots and it
is also a damping off agent
