New Study Reveals Surprising Insights Into Tar Spot Management

A new study led by a team of researchers from Michigan State University and FMC Corporation, has challenged conventional wisdom in the management of tar spot, a significant corn pathogen in the U.S. and Canada.

Contrary to previous assumptions, the study found no evidence supporting a relationship between nitrogen application rates and tar spot severity. The research suggests that nitrogen application does not influence the severity of tar spot.

Key Findings:

  1. No Relationship Between Nitrogen (N) Application and Tar Spot Severity: The study found no evidence supporting a relationship between nitrogen application rates and tar spot severity. The research suggests that nitrogen application does not influence the severity of tar spot.

  2. Plant Population Density Impact: Higher plant population densities were unexpectedly associated with lower tar spot severity.
