Dry weather in the Upper Midwest reduces mycotoxin threat

Last year at this time, there was concern in the Upper Midwest about mycotoxins in the feed because it was quite rainy before the corn and corn silage harvests.

This year, it's been the opposite. Dry weather has significantly reduced the mycotoxin threat.

"In general, it was a good year for us," says Alvaro Garcia, extension dairy specialist at South Dakota State University. "The quality is there. We have good corn silage this year."

Starch in the corn should be more than adequate, he adds.

However, just because the crop itself was good doesn't mean a person can rest easy. Problems can still arise with poor silage management.

Indeed, if mycotoxins occur in the Upper Midwest or Central Plains this year, it will be more a matter of the silage not being put up properly and conserved rather than the corn plant itself, Garcia says.

When it comes to silage management, Garcia says he tries to put a lot of emphasis on proper compaction of forage going into piles or bunker silos.
