Abstract

Yellow mold of peanut (Arachis hypogaea) seedlings caused by Aspergillus flavus was first observed during May 1984 in a commercial peanut farm in south Texas. The mold caused preemergence rotting of peanut seed and seedlings. On emerged seedlings the infection was largely restricted to cotyledons. The diseased plants were chlorotic, stunted, and leaflets were reduced in size with pointed tips and vein-clearing. Aflatoxins were found in cotyledons of infected seedlings but not in roots, hypocotyls, or leaves. A. flavus was the predominant fungus in the seed lot planted by the grower. Six isolates of A. flavus isolated from the seed and diseased seedlings were pathogenic to peanut in greenhouse tests.
