ABSTRACT
Aeromycological investigation was conducted over Catharanthus roseus field at Raipur (C.G.) during Nov. 2002 to Oct. 2003, to find out the percentage frequency and abundance of aeromycoflora, with the help of gravity Petriplates method. During present investigation Aspergillus niger (100%), A. nidulans (91.66%) and Curvularia lunata (75%), shows maximum percentage frequency while Alternaria cheiranthi, Aspergillus chevilieri, Cunnighamella echinulata, Fusarium oxysporum, Paecilomyces varioti, Penicillum herquei, P. rubrum, Phoma humicola, Syncephalastrum racemosum, Torula sp. and brown sterile mycelium (8.33%) with minimum frequency. It has been also observed that Cladosporium cladosporioides (24.36%) was most abundant fungi while least abundant species were Aspergillus chevalieri and Penicillium herquei (0.05%). Maximum abundance class was Zygomycotina recorded in rainy season, Ascomycotina in summer and Deuteromycotina were recorded in winter season. Similarly minimum percentage abundance of class Zygomycotina and Ascomycotina were recorded during winter season while Deuteromycotina in rainy season.
