Bacterial Wilt on Cucumber Vines

Commonly affects: Cucumis sativus (Cucumber)

Individual leaves wilt during the day, then the whole vine collapses within days. Cutting a wilted stem and slowly pulling the cut ends apart produces a sticky, stringy bacterial ooze.

Potential Causes

  1. 1Erwinia tracheiphila bacteria, transmitted almost exclusively by cucumber beetle feeding
  2. 2Striped or spotted cucumber beetles carrying bacteria between plants
  3. 3Wounds from beetle feeding giving bacteria direct vascular entry

Solution Steps

  1. 1Remove and destroy affected vines immediately — there is no cure
  2. 2Control cucumber beetles aggressively from the seedling stage with row covers, removed at flowering
  3. 3Avoid working around plants after handling beetles
  4. 4Monitor remaining vines closely for early symptoms

Prevention Tip

Since no cucumber variety is fully resistant, controlling cucumber beetles from planting onward is the only real prevention for bacterial wilt.
