Symptoms:
Older leaves on verticillium wilt-infected plants begin wilting at leaf margins and turn yellow, then brown. Plants are stunted and wilting is not alleviated by watering. A light tan discoloration of the stem can be seen in cross section.
Control:
The disease develops more rapidly in cool weather. The most effective control is planting one of the widely available resistant varieties.
