This year has been a particularly bad one for fire blight on Pear and Apple trees. Fire blight is a bacterial disease that affects plants in the Rosaceae family, causing a characteristic blackened wilting of leaves and twigs. This family of plants is also popular for its landscape value, both for flowers and fruit production. Pear, Cherry, Rose, Apple, Serviceberry, Cotoneaster, Hawthorn are just a few trees and shrubs that are very familiar to us. Have you noticed a profusion of dead, blackened leaves in your neighborhood? In your trees?

- Cherished for its white flowering show in the Spring but dreaded for its poor structure, weak stem attachment and susceptibility to fireblight (a lethal bacterial disease) and lecanium scale (a challenging insect pest to manage).
This tree has reached epidemic proportions through over planting and by the high volume of escaped seedlings along highways, abandoned fields and unmanaged areas.
Ohio added Callery pear to the Invasive species list in 2016.
