It’s easy to take coffee for granted, as it’s so readily available. The reality, however, is that the coffee industry in Central America is in turmoil. Coffee growers are experiencing the worst epidemic of coffee leaf rust, or ‘roya,’ that they’ve seen since this disease was first discovered in 1976.

Leaf rust is a fungal pathogen that infects coffee plants and causes them to shed their leaves. This inhibits photosynthesis and the plants die. It also prevents the current season’s berries from ripening and lowers carbohydrate accumulation in roots and shoots, which is where the next season’s berries are supposed to grow.
