Fungi associated with post harvest diseases of mandarin orange

Isolation carried out from infected mandarin fruits and recorded association of three fungi viz; Aspergillus niger, Penicillium digitatum and Rhizopus stolonifer and pathogenecity of all three isolates were proved. The pathogen Aspergillus niger produced brown to black lesions on fruits. Penicillium digitatum produced greenish spots on fruits. Rhizopus stolonifer produced blackening thereafter inducing severe rotting.
