Apple Scab & Rust Treatment for Trees | Prevent Leaf Loss with Timely Fungicide Sprays
Apple scab and rusts are fungi that affect the leaves and fruit of the host trees. If left untreated, they can cause unsightly discoloration and premature leaf drop, typically by midsummer. This stresses the tree because it decreases the tree’s ability to create food for itself through the photosynthesis process. Two annual sprays are effective at controlling these damaging fungi. The first application is done when the leaves first start emerging, and the second application is done after the tree is done flowering. Once applied and allowed to dry (typically within 30–45 minutes), the treatment becomes rainfast—meaning it won’t wash away in the rain.
After a particularly tough year for apple scab in 2025, many trees suffered damage. Now is the perfect time to get ahead of the issue. Contact Garpiel Group today to schedule your preventative treatment and keep your trees healthy and beautiful all season long.
