How to Prevent and Treat Fire Blight in Southern California


What is Fire Blight?

Ornamental Fruit Trees are a beautiful addition to any landscape and yet, they are susceptible to diseases.

A disease such as Fire Blight, which affects all varieties of Pear and Apple trees, creates unsightly withered leaves and branches.

The University of California Agriculture and Natural Resources Statewide Integrated Pest Management Program describes Fire Blight as, a common and frequently destructive disease of pome fruit trees and related plants caused by the bacterium Erwinia amylovora. 

Pear (Pyrus species) and quince (Cydonia) are the tree most often effected by fire blight. It can also effect Apple, crabapple (Malus species), and firethorns (Pyracantha species). Less likely to effected are hawthorn (Crataegus species), Spiraea, Cotoneaster, toyon (Photinia species), juneberry or serviceberry (Amelanchier species), loquat (Eriobotria), mountain ash (Sorbus species), and other related plants.

The name “fire blight” comes from the scorched look of the dead, blackened leaves and fruit clinging to dead branches.

Moreover, it can eventually lead to the death of the tree and the loss of a significant investment.
