Target Spot Control in Tomatoes
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.
Timing Is Everything
A timely fungicide application prior to infection is the best way to control the disease. DuPont™ Fontelis® fungicide provides excellent control of target spot in tomatoes and other fruiting vegetables, as well as other fungal diseases including Alternaria blights and leaf spot, early blight and Septoria leaf spot.
Applied at a rate of 16 to 24 fluid ounces per acre, Fontelis® can be applied at 7- to 14-day intervals, depending on disease pressure. It provides excellent crop safety and is rainfast within one hour of application.
