Scab is a harmful disease that affects apple trees, reducing the harvest, causing branch death, and creating dark spots on the fruit. To prevent scab and ensure a healthy apple harvest, autumn treatment is essential. Here’s how to protect your trees effectively.

How to Protect Apple Trees from Scab in Autumn

  • Fungicide Treatment: Begin by using fungicides to protect your trees from scab. While this is an important first step, it is not enough on its own for long-term prevention.
  • Cleaning Leaves and Fruits: Collect and remove all fallen leaves and mummified fruits, as they may harbor scab spores. Burn them or dispose of them away from the garden to prevent reinfection.
  • Treatment with Iron Sulfate: Use a 5% solution of iron sulfate for autumn treatment. You can mix it with urea to boost its effectiveness. For better adhesion, consider adding citric acid and liquid soap to the mixture.
  • Spring Treatment: Don’t forget that spring processing is crucial too. Apply another treatment to protect the trees from scab and ensure the pathogens don’t become resistant to the chemicals.

Conclusion

By following these steps—fungicide treatment, cleaning fallen debris, applying iron sulfate, and ensuring spring treatments—you will help protect your apple trees from scab and maintain their health and productivity for the upcoming season.
