Studies on the interaction between Sclerotium bataticola and Aspergillus flavus.

Metabolic products of Aspergillus flavus Link had a toxigenic effect upon Sclerotium bataticola Maub., decreasing its radial expansion and dry weight and enhancing sclerotial production. Metabolites of S. bataticola significantly lowered conidial output, slightly decreased the mycelial harvest but did not influence the linear spread of A. flavus. A. flavus, elaborating aflatoxin B1 (Rf 0.56), showed fluorescent spots identical to the original but with lower Rf value of 0.25 upon treatment with metabolic products of S. bataticola which itself exhibited fluorescent spots.
