More and more reports are coming in of corn testing positive for vomitoxin, with levels as high as 6-10 ppm in some cases. Some of these numbers are taking producers by surprise. Although the weather has been favorable for ear rot development, and consequently, grain contamination with vomitoxin, test results could be misleading in some cases, and may even be incorrect. Since there is not a lot you can do about grain contaminated with mycotoxins, you should at least check to make sure that you got a fair test.
