Rust Fungus

Rust Fungus is a big problem in Colombia and beyond, found in many coffee producing countries. Known as La Roya in the Americas, this disease diminishes fruit production and ultimately kills the plant. Combating the disease with selectively-applied fungicides, especially in seasons with heavy rains, is key to saving the coffee plants. Natural techniques to combat Roya are to prune shade trees and create more light for coffee, prune coffee to create light and air flow within and between the trees, and to keep the ground clean of affected leaves.
