Tree Rust Control

Tree rust control is needed when infected trees show yellow to orange leaf or needle pustules, or branch growth swellings with horn-like projections. Repeated outbreaks can result in severe defoliation, which can weaken trees and make them vulnerable to winter injury, insects and other diseases.
