Peach Leucostoma Canker: A Guide for Home Orchardists
Peach leucostoma canker is a common fungal disease that affects peach trees and other stone fruit trees, such as apricots, plums, nectarines, and cherries. It can cause serious damage to trees, leading to reduced fruit yields and even tree death.
Symptoms of Peach Leucostoma Canker
The symptoms of peach leucostoma canker include:
- Gum-like sap seeping from the tree near a previous injury
- Dead or dying branches
- Cankers (sunken areas) on the bark
- Wilting leaves
- Reduced fruit production
Causes of Peach Leucostoma Canker
Peach leucostoma canker is caused by a fungus that enters the tree through wounds or injuries. These wounds can be caused by pruning, storms, or other orchard maintenance activities. The fungus then spreads through the tree’s vascular system, causing cankers to develop.
