Black spots on any portion of the plant.

Cause(s):

Early blight, caused by the fungus Alternaria solani, is one of the most common diseases of tomatoes in Virginia. It occurs to some extent every year wherever tomatoes are grown. In spite of its name, the disease may occur at any time during the growing season. The fungus attacks leaves, stems and fruit. It can also cause disease on potato, pepper, and eggplant.

Control(s):

Leave enough space around the plants so that they may dry off after a rain.  Practice good crop rotation.  Where possible irrigate with a soaker hose versus  watering from overhead.  A fungicide can be applied.
