ABSTRACT

 

Four different isolates of fungi were discovered from the phylloplane of Arhar. They were recognized and identified to be Fusarium solani, Paecilomyces marquandii, Aspergillus niger and Aspergillus flavus. Similarly, from the diseased leaves of Arhar two pathogens were isolated, characterized and identified to be Curvularia lunata and Sterile. These fungal isolates were cultivated on seven different culture media viz., Czapek’s Dox Agar, Potato Dextrose Agar (PDA), Oat Meal Agar, Rose Bengal Agar, Richard’s Synthetic Agar, Sabouraud’s Dextrose Agar and Malt Extract Agar. Right after seven days of incubation at 250C, the mycelial growth rate, colony character and sporulation patterns of these fungi were evaluated. The type of growth media utilized had a significant impact on the diameter, cultural traits and sporulation of a few selected test fungi. On PDA and Richard’s synthetic agar media, Fusarium solani, Aspergillus niger and Curvularia lunata recorded the superlative radial growth. In PDA and Sabouraud’s dextrose agar Aspergillus flavus and Sterile recorded the highest growth. Paecilomyces marquandii recorded the maximal radial growth in Sabouraud’s dextrose agar.

Keywords    Arhar, Cultural characters, Different growth media, Leaf spot pathogens, Phylloplane fungi.
