ABSTRACT

Species of Aspergillus were the most prevalent fungi isolated from 51 samples of damaged flue-cured tobacco of the 1966 U.S. crop, comprising 57% of the total isolates. Other prevalent fungi were Penicillium (16%), Alternaria (8%), Cladosporium (4%), and Chaetomium (4%). Members of the Aspergillus glaucus group were isolated most frequently from samples with moisture contents ranging from 18 to 28%, whereas Alternaria, Cladosporium, and Penicillium were isolated consistently from samples containing 24 to 32% moisture. Aspergillus niger was prevalent in tobacco ranging in moisture content from 18 to 30%.
