Corn tar spots found in central Iowa

Tar spots for corn disease have been identified in central Iowa.

Allison Robertson, a pathologist at the Iowa State University Expansion Plant, says the detection happened on June 29.th In a plot of a seed company in Marshall County.

“And it was confirmed at the Industrial Plant Disease Clinic on the morning of the 30th.”

She says the infection occurred in the brownfield weeks earlier than in recent years, blaming the cool and moist start to the growing season.

“Since that report in Marshall County, I have received two more reports from scouts.”

Robertson says one report is from Jones County in eastern Iowa and the other is from Muscatine County in southeastern Iowa.

She encourages corn farmers to look for irregularly shaped black spots from small black circles that do not scratch the surface of the leaves of the lower canopy.
