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.

The disease develops more rapidly in cool weather. The most effective control is planting one of the widely available resistant varieties.
