There was only one new confirmed report of mycotoxins in crops in the U.S. this week, according to Neogen’s Monday Mycotoxin and Crop Report from August 13.
The first confirmed report of fumonisin in corn came from Texas. Previous reports of aflatoxin in corn came from Texas and Kansas.
“In areas with dry conditions and above-average temperatures in the forecast, a lack of adequate subsoil moisture will increase the risk of aflatoxin” in corn, Neogen said.
Previous reports of DON in winter wheat from Wisconsin, Ohio, New Jersey, Michigan, Pennsylvania, Indiana, North Carolina, Maryland, Delaware, Tennessee, Virginia and Illinois.
A previous report of DON in barley came from Pennsylvania.
