Is this Scab Disease on my young Comice Pear Tree? #873772
Asked June 19, 2024, 12:26 PM EDT
Hello, I filled out the information on the OSU Extension, but the submit button didn't seem to work, so here I go again. I have a 3 year old Comice Pear Tree, it has bear fruit, but most of it has dropped as it looks like either the birds, or squirrels were trying for it. The last couple of weeks, the tree has changed completely to some brown/black spots to full-blown spots on the leaves and now they're dropping. The tree is ill and I would like to know what I should do? I applied Captain Jacks for organic gardening and have sprayed the leaves only once. What kind of treatment spray does the tree need and when and how? It was healthy prior. It is planted next to a very old apple tree that has numerous illnesses, but seems to produce a few apples each year. Not sure if it caught something from the apple tree?
Thank you for your time,

Thank you Patricia, a friend of mine has an orchard of mostly 400 different varietal of apple trees and some pear. She is also having these same issues with her trees and believes it is pear scab. We had plenty of heavy rain for 2 weeks and I would imagine that impacted the trees. I've never sprayed the tree and the leaves are definitely impacted with brown spots all over. They have not turned yellow either and I've lost about half.
Thank you for your input-
