Compendium of Coffee Diseases and Pests

Coffee Leaf Rust, also known as Roya in Central and South American countries, is a fungus that has been grabbing headlines in recent years for its devastating effect on coffee crops totaling more than $1 billion in losses since 2012, according to USAID.

In addition to Coffee Leaf Rust, there are many other diseases as well as insects, mites, and nematodes attacking coffee crops. These disorders have hurt growers, as well as consumers, making coffee beans more scarce and, in turn, more expensive than ever across the world.
