Definitions
Blight canker is a plant disease caused by a fungus that attacks the bark and cambium layer of the plant, leading to the formation of cankers or lesions on the trunk or branches. The cankers are often sunken, discolored, and cracked, and may ooze sap or exude a foul odor. The fungus responsible for blight canker can spread through wind, rain, insects, or pruning tools, and can affect a wide range of trees and shrubs, including fruit trees, ornamental trees, and conifers.
Origin
The origin of blight canker is not clear, but it is believed to have been present in various parts of the world for centuries. The first recorded outbreak of blight canker in the United States occurred in the early 1900s, when it affected apple orchards in the Pacific Northwest. Since then, blight canker has spread to other parts of the country and has become a major problem for fruit growers, nursery operators, and homeowners.
