Aspergillus Ear Rot — Maize

Symptoms

Powdery fungal growth develops on kernels and the cob. A. flavus and related species may produce yellow-green spore masses. A. niger produces black, powdery spore masses. Affected kernels may become discoloured and deteriorate, especially under high-moisture conditions. A. flavus and A. parasiticus can produce aflatoxins, which are harmful to humans and animals.
