Pests in Gardens and Landscapes

Verticillium wilt—Verticillium dahliae

Verticillium wilt often starts as a yellowing between the major veins of the leaves. The fungus moves throughout the plant and eventually whole leaves and stems wither and die.

Solutions

Verticillium wilt of tomatoes can be avoided in many cases by planting resistant varieties, which are labeled V. If you wish to grow susceptible varieties, problems can sometimes be minimized by removing all residue, including roots that may be susceptible, and using soil solarization before you plant.
