Management Strategies for Sooty Blotch and Flyspeck on Apples
Sooty blotch and flyspeck are fungal diseases that can affect apple crops, causing unsightly blemishes on the fruit. Implementing effective Management Strategies is crucial to minimize their impact on fruit quality and yield.
Key Takeaways:
Cultural Practices
- Remove alternate hosts, such as wild plants, from the orchard and its perimeter to reduce spore production.
- Thin fruit to separate clusters, promoting better drying conditions and reducing disease spread.
- Prune trees to open the canopy, improving air circulation and reducing humidity.
Fungicide Application
- Utilize fungicides during the mid-June to August period, focusing on targeting spores before they infect fruit.
Orchard Hygiene
- Mow regularly to reduce orchard humidity and discourage fungal growth.
- Implement proper orchard sanitation by removing fallen fruit and other plant debris that can harbor the fungi.
By adopting these Management Strategies, growers can effectively control sooty blotch and flyspeck, preserving apple quality and maximizing crop yields.

Disease Cycle
Sooty blotch and flyspeck are caused by a complex web of fungi that thrive in warm, humid environments. The disease cycle for both begins in the spring with the release of fungal spores from infected plant material, such as overwintering apple twigs. These spores are carried by wind and rain throughout the orchard and can infect young fruit as soon as petal fall.
Once inside the fruit, the fungi grow and develop, feeding on the fruit’s surface. This causes the characteristic black spots or smudges that detract from the appearance of the fruit. The symptoms of sooty blotch and flyspeck are most severe in late summer and fall when the weather conditions are most favorable for fungal growth.
Key Takeaways:
- Fungal spores overwinter on infected apple twigs.
- Spores are windblown into orchards, infecting fruit after petal fall.
- Sooty blotch and flyspeck are most common in late summer and fall.
- Symptoms include black spots or smudges on the fruit’s surface.

FAQ
Q1: How can I identify sooty blotch and flyspeck on apples?
A1: Sooty blotch appears as sooty or cloudy blotches with indefinite borders, while flyspeck manifests as sharply defined black specks. They are surface blemishes that do not cause fruit decay.
Q2: What are the most effective strategies for managing sooty blotch and flyspeck?
A2: Remove alternate hosts from the orchard, thin fruit to improve drying conditions, prune trees to open the canopy, use fungicides during mid-June to August, mow regularly to reduce humidity, and practice proper sanitation.
Q3: How do sooty blotch and flyspeck diseases spread in an orchard?
A3: The fungi that cause sooty blotch and flyspeck are windblown and infect fruit throughout the orchard, especially during mid-to-late summer. Spores are primarily produced from wild plants along orchard borders.
Q4: What is the disease cycle of sooty blotch and flyspeck?
A4: The fungi that cause sooty blotch and flyspeck overwinter on infested apple twigs and reservoir hosts. Spores are released in the spring and infect fruit through wind dispersal. The diseases develop on the fruit surface, causing blemishes.
Q5: How can I prevent sooty blotch and flyspeck in my apple orchard?
A5: Control strategies include removing alternate hosts, thinning fruit, pruning trees, and using fungicides. Proper orchard sanitation is also crucial to prevent the buildup of inoculum.
