Verticillium dahliae and V. albo-atrum
Vascular wilt disease that infects a plant through the roots. Initial symptoms include leaf wilting and yellowing. Vascular tissue appears brownish in cross section. Plants eventually collapse.
Fungus survives in infected fields for several years. Crop rotation, soil sterilization and soil solarization are the only effective controls. No genetic resistance is available.
