Jamie Loecker, an agronomy service manager at Syngenta, discussed the emergence of tar spot in the Midwest, particularly in Indiana, Missouri, Iowa, Kansas, Nebraska, and possibly Illinois. Tar spot appears as black flecks on corn leaves and can be mistaken for insect feces. Early detection is crucial for managing 2026 corn disease risk, with fungicide applications recommended at the V14 stage or pre-tassel.
