Some Iowa corn growers are finding a new type of disease on the leaves of their crops.

Plant pathologist Doug Jardine says the disease streaks the leaves and somewhat resembles “gray leaf spot” but it’s different.

Jardine says with corn maturing and drying, it likely won’t spread any further this season.

The new disease is being called X-V-V and researchers don’t know how it got here, how to control it or even whether it needs to be controlled.

The big question is — will it reduce yields?

Jardine says anytime you get something new that has the potential to impact the corn crop, it’s a big deal in the heartland, especially in Iowa where corn is king.

X-V-V has been found in nine states so far, including Iowa, Nebraska, South Dakota and Minnesota.
