Apple Scab Treatments
Protect Your Crabapples, Hawthorns, Serviceberries and Apples from Apple Scab/Rust
Apple scab/Rust is one of the most common fungal diseases affecting crabapple, hawthorns, serviceberries and apple trees in Northern Illinois. It causes dark, velvety spots on leaves and fruit, leading to premature leaf drop and weakened trees. Repeated infections can reduce flowering, stunt growth, and diminish your trees’ beauty year after year.
Our Treatment Program
Crabapple spraying for apple scab in Northern Illinois typically starts in early to mid-April, around bud break or when green tissue first emerges. This timing is crucial because fungicide applications are most effective when applied preventatively before primary infections occur.
