treating fire blight on young fruit trees

Asked March 4, 2016, 3:49 PM EST

I've got a number of 3 to 4 year old apple and pear trees that have fire blight damage to the lower trunk and limbs. Some trees have died. Can this be effectively treated and the trees saved. If so, what is the best treatment? Are there apple and pear tree varieties that are less susceptible to fire blight?

Fire blight is a bacterial disease that can affect apples and some pears. Here in Columbia County, Asian pears seem most affected. I would be happy to visit your trees and look at the symptoms to make sure it is fire blight on the apples. Last year, the weather and humidity conditions did favor the disease. Many years, they do not. Give me a call at the Extension office to set up a visit (Chip Bubl, OSU/Columbia County Extension office 503 397-3462). Here are some discussions from our Plant Disease Handbook relative to fire blight:
