How Does Coffee Leaf Rust Affect Coffee Production on the Big Island
Sep 26th 2022
Coffee leaf rust or CLR is a fungus that kills coffee trees worldwide. As of today, there is no real protection against it, only products that slow down the infestation for a limited time.The impact of this disease is very fast defoliation of trees and very rapid death if not treated. Coffee leaf rust causes coffee yields to be reduced substantially. Coffee leaf rust was not found in Hawaii until just about 1 year ago. This makes Hawaii the last coffee region in the world to be impacted by CLR.
