Best Treatment for Probable Fire Blight

Asked July 4, 2016, 11:09 AM EDT

We have one 30ft Oriental Cleveland Pear tree. Some of it's leaves are turning black and falling. Can we save the tree? It does not seem wide-spread...yet. This is a tall tree, would an expert arborist be helpful in saving this tree?
Respectfully,

Hi Paul -

Fire blight can be managed with two different fungicides in the spring. The product of choice will contain the antibiotic streptomycin. This product is sprayed when the plants are in flower. The other option will be a copper-based fungicide. You'll also have to prune out the infected branches about 8" below the area showing the sign of the disease and disinfect the pruners in a 10-1 bleach solution (10 parts water 1 part bleach). Please visit the link I am including and let me know if you have further questions
