BLACK CANKER Meaning and
Definition
-
Black canker is a destructive plant disease caused by various species of fungi that specifically affects woody plants, particularly fruit trees, such as apple, pear, and cherry trees. The term "black canker" is derived from the characteristic dark, sunken lesions or cankers that develop on the bark, branches, or trunks of infected plants. These cankers are typically accompanied by other symptoms like browning, wilting, and eventually death of the affected tissues.
The fungi responsible for black canker invade the host plants through wounds or natural openings, such as leaf scars or pruning cuts. They then establish colonies in the affected tissues, growing and spreading to nearby healthy tissues. This leads to the development of the characteristic black cankers, which often exude sticky black fluids or resins.
Black canker poses a significant threat to tree health and productivity, as it can cause extensive damage and even death if left untreated. The disease is highly destructive to both young and mature plants, impacting their growth, yield, and overall vigor. Moreover, it can contribute to the vulnerability of the plants to other diseases and pests.
Preventing and managing black canker involves several measures, including practicing good sanitation by removing and destroying infected plant parts, promoting proper tree care and nutrition, and employing appropriate fungicides or other control methods as recommended by experts. Timely and accurate diagnosis of the disease is crucial to initiate effective management strategies and minimize its impact on affected plants.
