What trees does fire blight affect?

Fire blight, caused by the bacterium Erwinia amylovora, is a common and frequently destructive disease of pome fruit trees and related plants. Pear (Pyrus species) and quince (Cydonia) are extremely susceptible. Apple, crabapple (Malus species), and firethorns (Pyracantha species) also are frequently damaged.

Pears are the most susceptible, but apples, loquat, crabapples, quinces, hawthorn, cotoneaster, Pyracantha, raspberry and some other rosaceous plants are also vulnerable. The disease is believed to be indigenous to North America, from where it spread to most of the rest of the world.

Secondly, what can I use for fire blight? During spring and summer, prune out infected branches 8 inches below the damage. Avoid pruning when the plants are wet. Dip pruning tools in 70 percent isopropyl alcohol (rubbing alcohol) or 10 percent bleach solution (1 part bleach to 9 parts water solution) between each cut. Wash and oil shears when you are finished.

How do you stop fire blight?

Avoid heavy pruning or excess applications of nitrogen fertilizer, both of which encourage new growth. Avoid planting close to wild plants of hawthorn, apple or pear. As soon as fire blight is discovered, prune off infected branches 1 foot below the diseased sections and burn them to prevent further infection.

Does fire blight stay in the soil?

In the spring, the bacteria are dispersed by insects, rain, wind, and animals. The bacteria build up on the plant hairs, stigmas, and other flower parts. Note that the bacteria do not survive free in the soil. The symptoms of fire blight include the rapid killing of branch tips and leaders, especially during flowering.

Will vinegar kill fire blight?

Treating fire blight is accomplished with pruning and the application of a white vinegar solution to create an acidic environment that the bacteria will find inhospitable. Examine the tree for any twigs or branches that are affected by the fire blight.
