Pear tree problems

Asked June 21, 2020, 11:12 PM EDT

I live in Seattle WA and have a mature pear tree that's developed orange spots on it's leaves and thick fungus type of growth on others. The tree had hundreds of pears on it until about a week ago when 98% of them fell off. We have sprayed it with fungicide but it persists. Do we need a different treatment?

My guess is you have pear rust. Sprays to control this disease are put on around bloom time so your sprays were applied too late.
Here is a link to a Washington factsheet on the disease.
