Kinnikinnick: Leaf spot
Leaf spot is a fungal disease. Symptoms include development of brown, necrotic spots on leaves. The fungus most likely overwinters on infected leaves and possibly on twigs. The disease is favored by cool, wet conditions and is spread by splashing water.
Use Integrated Pest Management (IPM) for successful plant problem management.
Select non-chemical management options as your first choice!
- Rake and destroy fallen leaves.
- Remove and destroy infected leaves from plants, where practical.
- Avoid overhead irrigation.
- Space plantings and prune to improve air circulation. Avoid planting in moist, shady areas if leaf spot is a problem.
- The variety ‘Massachusetts’ is reported to be resistant to leaf spot.
