Abstract

Aspergillus ear rot in corn fields has been reported by Iowa State University Extension field crop specialists in southeast and south central Iowa. The concern with this disease is the production of aflatoxins, which are extremely toxic chemicals produced by two molds Aspergillus parasiticus and Aspergillus flavus. Aflatoxin accumulation is usually associated with poor storage conditions. However, hot, dry conditions during grain fill increase the risk of Aspergillus infection and aflatoxin contamination in the field.
