Deoxynivalenol (DON) has been confirmed in winter wheat in six U.S. states, according to Neogen’s Monday Mycotoxin and Crop Report from July 2.
DON was found in winter wheat in North Carolina, Maryland, Delaware, Tennessee, Virginia and Illinois.
Deoxynivalenol develops during warm, wet weather and is one of the most important mycotoxins because it occurs frequently and at levels of toxicological relevance for swine.
Major grains planting has ended and crop progress is near normal, Neogen said.
Winter wheat is 83 percent headed out, on track with the five-year average. Sixty-four percent of the winter wheat crop is in good to excellent condition, compared with 73 percent at this time in 2017. Eleven percent of the crop is in poor to very poor condition, compared with 8 percent in 2017. Forty-one percent of winter wheat has been harvested, eight points ahead of the five-year average of 33 percent.
Spring wheat is 34 percent headed out, seven points ahead of the five-year average.
Barley acres are 28 percent headed, four points behind the five-year average.
Corn conditions across the country are 77 percent in good to excellent condition, which is the same as this time last year. Five percent of corn is in poor to very poor condition, which is 3 percent lower than last year.
