More tar spot is being reported

A plant pathologist says he’s getting more reports of corn tar spot.

Dr. Damon Smith with the University of Wisconsin tells Brownfield more farmers are calling in tar spot reports. “Over the last week or so, it has slowed, the progression has slowed a little bit compared to 2021 so I think we’re going to be somewhere in terms of final disease severity somewhere between 2020 and 2021.”

Smith expects there will be some yield reductions on some of the more susceptible hybrids, and some of the hybrids with more resistance might come through without any issues, but he says farmers need to scout often.
