Target Spot Control in Tomatoes

Target spot on tomatoes can be confused with bacterial spot and early blight.

A major problem in tomatoes, target spot is caused by the fungus Corynespora cassiicola. The pathogen has a wide range of hosts and can survive in crop debris for up to two years. Its spores are primarily spread through the air in midmorning at air temperatures around 82 degrees.

Target spot signs, especially in the early stages, can be confused with those of bacterial spot and early blight, so lab tissue tests are recommended to confirm the disease.
