Disease enters through the roots and plugs water conducting vessels. Destroy infected plants. Use plants that are resistant to Fusarium and Verticillium Fungi. Leaves and stems wilt. White fungus may encircle the stem.
Plant roots rot.
Remove and discard infected plants. Let soil dry between watering and plant only in well drained soil. Leaves have a speckled appearance. Dry, brown blotches develop. Leaves distort and fall off.
