Abstract
A survey of preharvest corn (Zea mays L.) in 31 counties in the Coastal Plain Region of Georgia suggested that ears molded by Aspergillus spp. of the Aspergillus flavus group and ears damaged by insects were widespread in about 810,000 ha (2 mllion acres) of corn grown in the area. Ninety percent of the field‐collected samples contained aflatoxin in excess of 20 µg/kg. Averagear damage by insects ranged from a low of 1.4 cm to a high of 8.9 cm. Highly significant correlations were found between insect damage and percentage of ears with visible A. flavus ear mold, between insect damage and aflatoxin contamination, and between percentage of ears with visible A. flavus ear mold and aflatoxin contamination.
