Tomato pith necrosis has been observed recently in a high tunnel. This disease is caused by a bacterium. Although observations of this disease in Indiana are infrequent, growers should scout their production for tomato pith necrosis. Management options include avoiding excessive nitrogen fertilization and high humidity.
