“It?s going to take a really unique year if we?re going to see it here, and we?re having that unique year,” said Joe Lauer, an agronomy professor at UW-Madison. Lauer said farmers also need to be on the lookout at harvest time for toxins from another genus of fungi called Fusarium. Those toxins can cause milking cows to become less productive and can induce farm animal miscarriages if ingested in high enough concentrations.
