The fungus is windborne and rainand is favored by wet weather. See Table 2 . Leaf infection produces brown lesions with dark brown borders. The fungus can also invade branches, twigs and tendrils causing brown cankers that kill distal plant parts. See Table 2.
Affected plants exhibit increasing periods of wilt until plant death occurs.
During moist weather, the stem cankers may exhibit a white to pink fungal growth. Root knot nematodes may accelerate disease. Cultivar exhibit more vigor if grafted onto yellow passion vine root stock. No EPA-registered products exist. Root disease can be expected to be more severe with root knot nematode parasitism on the same root system.
