BARK CANKER Meaning and
Definition
-
Bark canker refers to a specific type of disease or infection that affects the bark of trees. It is characterized by the formation of open sores or lesions on the bark, which may manifest in various sizes and shapes. The cankers usually appear as raised or sunken areas on the tree's outer layer, often disrupting the natural patterns of the bark.
Bark cankers are commonly caused by fungal pathogens or bacteria that infiltrate the tree's bark tissue, leading to damage and decay. These pathogens are typically introduced through wounds or injuries on the tree's surface, such as pruning cuts, insect feeding sites, or mechanical damage. Once the pathogens enter the bark, they start to multiply and spread, eventually causing the formation of cankers.
The symptoms of bark cankers may vary depending on the specific pathogen involved and the tree species affected. Some common signs include bark discoloration, oozing of sap or resin, and the presence of fungal fruiting bodies or spore-producing structures. In some cases, the cankers may enlarge and girdle branches or even the main trunk, leading to reduced sap flow, wilting, and dieback of the affected tree parts.
Bark canker can pose significant threats to the health and vigor of trees, as it weakens their structural integrity and hampers their ability to transport nutrients and water. It can also serve as an entry point for secondary pathogens or pests, further deteriorating the tree's condition. Therefore, timely identification, prevention, and appropriate management practices are essential in minimizing the impact of bark canker on trees and maintaining overall forest and landscape health.

Etymology of BARK CANKER
The word "bark canker" is composed of two separate parts: "bark" and "canker".
1. "Bark": This term comes from the Middle English "barke", which can be traced back to the Old English "bærk". It has Germanic roots and is similar to words in other Germanic languages such as Dutch "schors" and German "Rinde". Essentially, it refers to the protective outer layer of a tree trunk, branch, or stem.
2. "Canker": The word "canker" has a different origin. It comes from the Old English "cancer" and has its roots in the Latin "cancer", which means "crab" or "cancer". In this context, "canker" refers to a progressive, localized disease or decay in plants, characterized by the death and destruction of tissues.
