I am sure it is not fireblight. The problem I think is related to the soil, possibly a poor drainage problem or a mineral unbalance in the soil. Sorry I could not be more help. Al

I have a similar problem in an area with poor drainage and pH of 8. We had a wet ("El Nino") spring, and the last rain was around June 1st, very unusual for California. If I find out what the problem is, I'll try to navigate back here to post it.

I think tree contain some fungus or bacteria in the phoem due to weather conditions like rain etc. Because of this, lack of nutrient supply. So, you have to buy some medicine or any product which save life of your pear tree.

It could be sunscald. Look if the leavers under the canopy are not as damaged. From the pictures it looks like only the upper leaves are affected but its hard to tell for sure. Cool cloudy weather followed by a period of hot sunny weather can scald leaves.

Hi,

I see you live in the Netherlands. I live near Kobenhaven.

My pears (nice mature trees and 1 years olds) all are diplaying the same symptoms. We have been having such a crazy spring and earlier summer that I would bet that is it some environmental variable causing the problem. Sun scald or too much rain are likely.

Scott, I have been following the forum for several years and I realy respect your opinion. What do you think about wind damage?

Sincerely,
Sam

Not fireblight.I happen to have currently a 20 feet high Comice tree with firebligh braught likely by insects or birds from neigborhood backyards with apple and pear trees showing fireblights.Very hard to control in an urban setting beacause people do not know nor take action to stop it.Close to this pear tree I have one Warren pear tree and one Flemish Beauty pear tree. Totally free from fireblight. They must be resistent to fireblight bacteria.
You likely have one of the following issuess:fungus
mites or lice, soil elememts deficiency or watering issue due to poor drainage. I suggest you take your leaves to a nursery for an expert to diagnose the problem.You also might send to a lab a sample for analysis.Eliminating the first 3 possibilities you might do a drainage test for your soil.The info to do it is in the net.Just google it.The result will give you an idea how to water the tree.
Good luck.Jaime.

A small update: by the looks it was indeed a sunscald. Since I was not sure what was causing the problem I did not do anything and it seems it was a good choice. The tree grew considerably this season and did not seem to be annoyed by the weird leaves.

I had something similar but it was BLACK SPOTS on the leaves. This is not fire blight. Fire blight cooks the stems and leaves and it has a shepard's crook look.
