Nearly black spots appear on leaves and lower stem; leaves turn yellow to brown. Early blight is a fungal disease spread by heavy rainfall and warm temperatures. Keep weeds down in the garden area; they harbor fungal spores. Avoid overhead watering.

Lower leaves yellow and die; stem is discolored with brown streaks when the stem is split lengthwise; plants wilt and die. Verticillium wilt is caused by a soilborne fungus. Plant verticillium resistant varieties. Rotate crops and avoid planting in soil previously planted with pepper, potato, tomato, or cucumber family members.
