Abstract
All 5 isolates of A. flavus (3 toxigenic and 2 non-toxigenic) studied were pathogenic to both injured and uninjured groundnut seedlings.Aflatoxin B1 was present in cotyledons infected with toxigenic strs. of A. flavus and slight amounts were seen in the leaves with 2 strs., but not with the 3rd moderately toxin-producing isolate. Traces of aflatoxin were present in injured cotyledons of plants infected with non-toxigenic strs.ADDITIONAL ABSTRACT:All 5 isolates were pathogenic to uninjured and injured groundnut seeds and produced characteristic symptoms. With injured seed, seed rot was greater and plant height lower. Two toxigenic isolates (M-11 and L-27) were highly virulent to both injured and uninjured seed, reducing germination and plant height considerably more than the non-toxigenic isolates
