Air-Borne Fungi Of Wheat Fields In Egypt

Abstract

The air borne fungi of wheat fields in El-Minya Governorate were studied during the periods January-May 1977 and December 1977-May 1978 using the plating catch method on 1% glucose and 50% sucrose-Czapek's agar. Fifty-two species and 24 genera were collected on the two types of media tested. The total counts of air-borne fungi displayed seasonal periodicities and the highest counts were estimated in March 1977 and 1978. The most frequent genera were Aspergillus (7 spp.), Alternaria (2 spp.), Cladosporium (2 spp.), Penicillium (2 spp.) and Fusarium (F. so/am only) on 1% glucose and 50% sucrose Czapek's agar media. Their counts showed almost regular seasonal fluctuations during the experimental periods.
