    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.

    We have had some scattered frosts around the state that have generated some questions about forage use after a frost.  The two most common questions concern the use of warm season grasses in the sorghum family and grazing alfalfa.  The issue with grasses in the sorghum family, which includes sorghum-sudangrass hybrids, sudangrass and Johnsongrass in addition to sorghum, is that they contain cyanogenic glycosides and enzymes that convert those compounds to free cyanide (sometimes called Prussic acid) within their cells.  Prussic acid or cyanide is a lethal toxin.
