UW-Madison Plant Pathology Prof. Damon Smith says while the tar spot risk has been high and folks are finding tar spot, overall the severity level -- how much disease is there -- is quite low right now.

"We haven't reached the upper canopy yet, we aren't seeing yield-limiting levels of disease yet," Smith says.

He says if farmers can get their corn crop through the risk window, they'll be outside of substantial yield reductions from this disease.
