Regional Notes

Verticillium Wilt (Potato Early Dying) can show up on landscape plants, producing visible damage that ranges from leaf spots and discoloration to branch dieback depending on severity. Early detection gives you the best management options.

Start with sanitation: remove and dispose of affected material as you find it. Thin dense growth to improve air circulation, and redirect irrigation away from foliage. If the condition persists despite cultural adjustments, your local Extension office can help identify the pathogen and recommend targeted treatments.

Management

Cultural Controls

  • Trees have recovered after proper cultural care.
  • Do not plant orchards in soils where Verticillium-susceptible crops (see above) have been grown previously.
  • Do not interplant with Verticillium-susceptible crops.
  • Control weeds.
  • Avoid excessive irrigation, severe pruning, or other measures that promote succulent growth.
  • Research on control of Verticillium wilt in other crops indicates that nitrogenous fertilizers should be used at minimum rates-sufficient only to provide normal growth.
