The ivy plant, or English Ivy, is an evergreen vine native to Europe, north Africa, and western Asia. It is susceptible to several diseases which damage the leaves on the vine.
The primary cause of ivy plant leaf disease is fungal or bacterial infection. Over 40 species of pathogens have been linked to ivy plant leaf disease.
The leaf diseases which affect ivy plant are Xanthomonas leaf spot, Colletotrichum leaf spot, Botrytis blight and Phytophthora leaf spot.
The signs associated with ivy plant leaf disease include dark brown, black lesions on leaves, spores within lesions and yellowing of the leaf.
Planting ivy plants under a covered structure and utilising drip irrigation reduces the risk of contracting leaf diseases. Infected leaves should be removed. Applying fungicide also combats leaf disease.
Plants with severe infection should be removed completely from the garden. It should be placed in a plastic bag, along with the soil near it.
