APPLE CANKER Meaning and
Definition
-
Apple canker is a plant disease that affects apple trees, caused by various species of fungi belonging to the genus Nectria. It is characterized by the development of lesions, or small open sores, on the bark, branches, and trunks of apple trees. These lesions often appear sunken, discolored, and cracked, with a reddish-brown or black coloration. The presence of cankers weakens the affected parts of the tree, leading to reduced growth, vitality, and overall productivity.
The primary mode of entry for the canker-causing fungi is through wounds or openings in the bark, such as pruning cuts, insect damage, or natural cracks. Once inside the tree, the fungi establish themselves and begin to spread, causing further damage to the plant tissues. In severe cases, cankers may girdle branches or even the main trunk, resulting in dieback and potentially leading to the death of the apple tree.
Favorable environmental conditions such as high humidity, moist conditions, and wounds from pruning or mechanical injury increase the vulnerability of apple trees to canker development. Therefore, proper orchard management practices, including timely pruning, removal of dead wood, and good sanitation, as well as the use of resistant apple varieties, can help prevent and manage apple canker infestations. Fungicides, when applied according to appropriate timing and dosage, can also be effective in controlling the disease. Prompt identification and management of cankers are crucial to minimize losses in apple orchards and maintain tree health.
