What does gummosis mean?
Gummosis is a technical plant-disease term for a condition in which a tree or other woody plant exudes a sticky, gum-like substance, usually from its trunk, branches, or other affected tissue. The flow may accompany infection, insect damage, mechanical injury, or other stress, although the symptom by itself does not reveal its underlying cause. Gummosis is especially associated with citrus trees and with stone fruits in the genus Prunus. Severe cases can produce open wounds, weaken branches, cause dieback, and sometimes kill affected parts of a plant. The word belongs to plant pathology and horticulture rather than everyday vocabulary. It should also be distinguished from a tree's normal production of gum, which can occur during ordinary growth or as a response to wounding. Knowing the term is useful to gardeners, orchardists, and readers of agricultural reports because it identifies both a recognizable symptom and the broader diseased condition associated with it.
nounA plant disease characterized by the exudation of a gum-like substance from bark or other tissues, commonly as a symptom of infection, injury, or other stress.
- A plant disease or pathological condition marked by the exudation of gum-like material from affected tissues.
"The oozing of sticky sap from the trunk was a clear sign of gummosis."
"Citrus trees affected by gummosis may develop lesions around the trunk and branches."
"The orchardist suspected gummosis after noticing dark, sticky patches on several trees."
The word is generally treated as a mass noun when naming the disease, but the standard plural is used when referring to separate cases.
"The survey documented distinct gummoses in several orchards."
Gummosis turns a tree's injury into a sticky ooze—its name points directly to the gum that leaks out.

Where does gummosis come from?
Gummosis was formed in the 19th century as a scientific term for a condition involving the production or exudation of gum. It combines the established English word "gum," which came through Latin gummi from Greek koummi, with the Greek-derived suffix "-osis," used in the formation of names for diseases or abnormal conditions. Its relatives include gummy, gummiferous, and gummite, all of which draw on the same ancient root for gum or gum-like resin.
How gummosis is actually used
This is a specialized term used in plant pathology, horticulture, and agriculture. It names a diseased condition rather than the gum or sap alone, and it is uncommon in general prose.
