The distribution and aflatoxin productivity of atypical sclerotigenic strains of Aspergillus flavus isolated from soils in Thailand were investigated. Out of the 27 soil samples from 8 provinces, 9 samples were detectable for the strains. Among these 9 samples, 7 were collected from the maize fields in two northern provinces: Chiang Rai and Chiang Mai. All of 11 isolates of the strains tested produced aflatoxins, while half of 24 isolates of the typical strains produced them.
