Quick Summary

Gummosis is a plant disease characterized by the pathological production of gummy exudate. This gummy substance is often collected from the bark of trees and shrubs, such as those in the pea family (Fabaceae).12

Trees may produce gum as a protective response to damage or attack from bacteria, insects, or fungi. Gummosis can manifest in various plant diseases, including those affecting citrus trees and sugarcane. While some gums are used commercially in cosmetics, pharmaceuticals, and foods, they are chemically complex compounds derived from carbohydrates.23
