Tar Spot in Sweet Corn: Be Alert!!
Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture
There is a new disease on the block for sweet corn in New York! Tar spot is a fungal disease found first in Indiana and northern Illinois field corn in 2015. It has since spread throughout the Midwest. The disease was found in western NY corn fields every year for the past 3 years, and in central NY last year. Tar spot has potential to severely reduce yields of susceptible corn varieties, so we are closely monitoring disease spread and impact.
