Hi there! I have some kind of bug I think on both my Bartlett Pear Trees. One is over 4 years old and the other is 2 years old and has just developed what looks like the same problem. I"ve scanned leafs from the tree to help with ID. The older tree has had this problem every year, and eventually all the leaves get it and wither. This year it seems to have less, but my 2year old tree now has what looks like the same thing! I have Anjou pears as well, and they don't have this problem. Thanks for any help you can give!
