Canker Control in Your Garden
Cankers are serious diseases of woody plants and shrubs, caused by either fungal or bacterial pathogens. Canker refers to a symptom of an injury, often associated with an open wound that has become infected by a pathogen.
These pathogens invade wounded plant tissues – caused by either natural or mechanical means – and typically results in excessive gum exuding from entry sites (gummosis), wilting and death of branches, and eventual death. The severity of canker depends on the environment, the age of the plants, and if the plants are under any other stress – these factors can all reduce plant defence reactions. Here, we explore the most common canker diseases and how to control them.
