Corn mold is getting old

摘要

Across the Corn Belt from Ohio to Colorado, grain quality experts and Extension staff are warning corn growers to be alert for Gibberella ear rot infections and the resulting potential for vomitoxin (deoxynivalenol or DON) and zearalenone mycotoxins in stored corn. This is when thorough scouting for ear rot at the black-layer stage pays off, says Alison Robertson, an assistant professor of plant pathology at Iowa State University. "Producers need to be thinking about any corn they harvested from fields where there was a mold problem," says Robertson.
