What Does Bacterial Wilt Look Like? Key Symptoms and Diagnosis

Learn to identify bacterial wilt by spotting sudden leaf wilting and stringy sap in cucumbers and melons. Early detection is vital.

50 views

Bacterial wilt manifests through sudden wilting and yellowing of leaves without the foliage recovering its turgidity at night. This disease primarily affects cucumbers and melons, noticeable when plants collapse as if drought-stressed despite adequate moisture. The key diagnostic feature is the stringy or ropy sap when a stem is cut and slowly pulled apart. Additionally, if you place a bit of this ooze in water, it'll stretch out in a thread, confirming bacterial presence. Early detection and removal of affected plants are critical to prevent spread.
