Two U.S. states have new confirmed reports of deoxynivalenol (DON) in wheat, according to Neogen’s Monday Mycotoxin and Crop Report from August 6.
There were new confirmed reports of DON in wheat in Wisconsin and Ohio. This is in addition to previous reports of DON in winter wheat came from New Jersey, Michigan, Pennsylvania, Indiana, North Carolina, Maryland, Delaware, Tennessee, Virginia and Illinois.

Crop progress, condition
Eighty-five percent of winter wheat has been harvested, which is one point behind the five-year average. Late-season quality issues in winter wheat have emerged, including sprouting and lower test weights. Protein levels have been good, but DON levels are being monitored closely due to wide variability.
Spring wheat is 4 percent headed, which is on par with the five-year average. Seventy-eight percent of spring wheat is in good to excellent condition; 4 percent is in poor to very poor condition.
Barley is 97 percent headed out, which is one point behind the five-year average. Eighty percent of barley is rated in good to excellent condition, while 3 percent is rated in poor to very poor condition. Two percent of barley has been harvested; this is four points behind the five-year average.
Seventy-one percent of oats are rated in good to excellent condition, and 7 percent is in poor to very poor condition. Thirty-eight percent of oats have been harvested, which is three points ahead of the five-year average.
