Farmers are encouraged to start looking for symptoms of common corn diseases.
Corteva Agriscience market development specialist Jeff Moon says tar spot, northern corn leaf blight, and gray leaf spot could be seen across a lot of geographies this season.
“There’s been a lot of discussion about tar spot the last few years, and that footprint that it’s in seems to be growing a little bit. It seems to really like cooler temperatures but with high humidity.”
He tells Brownfield a foliar disease becomes more likely the longer leaves are wet.
