To get rid of peach leaf curl, you need to treat affected trees with a fungicide in the fall, after the leaves have dropped. This prevents the disease from taking hold the following spring.
Effective Fungicide Treatments for Peach Leaf Curl
Peach leaf curl is a fungal disease that causes leaves to become distorted, thickened, and reddish. Successfully treating it requires preventative measures, primarily a well-timed fungicide application.
Here's how you can approach it:
- Timing is Key: The most crucial step is applying the fungicide in the fall, after the leaves have fallen off the tree. This is the time when the fungal spores are most vulnerable.
- Fungicide Type:
- Historically, both lime-sulfur fungicide and fixed copper fungicides have been effective.
- When using a copper fungicide, ensure it contains at least 50% copper.
- Application: Thoroughly spray all parts of the tree, including branches and trunk, to ensure the fungicide covers all potential infection sites.
Summary Table
| Action | Timing | Fungicide Options |
|---|---|---|
| Apply Fungicide | Fall, after leaf drop | Lime-sulfur or Fixed Copper (min. 50% copper content) |
By following these steps, you can effectively manage and get rid of peach leaf curl on your peach and nectarine trees.
