Aspergillus ear rot is being detected in stressed corn this year.
Grain elevators are commonly screening harvested corn with a black light for
fluorescence, which may signal the presence of the fungus Aspergillus flavus
and its production of aflatoxin. This video describes the screening process.
A conclusive, and quantitative, test for the presence of aflatoxin is only
available by chemical testing. More information about aspergillus ear rot,
aflatoxin, testing, and FDA action levels can be found in Purdue Extension
Publication BP-83-W, Apergillus Ear Rot, which can be downloaded at:
