It all started Tuesday morning when I noticed my only fruit on the Bobier 845 was flat as a pancake. Within 24 hours, 30 or more leaves in the center of the plant turned brown and died. The stump had water seriously leaking out in 3 or 4 places, followed by this white foam. No fertilizer since the end of June has been used, and systemic and applied fungicides and insecticides were used. Any experts have a clue?
