A new infection of Fireblight bacteria is killing the end of the limb, wilting the leaves. Most likely a bee pollinated a diseased tree, then went to this tree and spread the bacteria. Can it be “saved”? Yes. Cut off the diseased parts when the tree is dormant, in the winter. Disinfect tools between cuts to avoid spreading it more. Treat in the spring and fall with Reliant and Pentrabark, or call us to do it for you. It can be found at Amazon as a bundle. Do it every spring and fall for the life of the tree since it is such a continual problem in Montana. \
The most common disease in Billings is Fireblight, as seen in this photo.
