Pear disease and Insect identification

[clarkinks]

Was there glysophate or other herbicide like it used near the trees? Sometimes lawn chemicals etc. are applied. Do you have voles or other underground pests?

What is wrong with my trees?

I have a small orchard of about 50 fruit trees, mostly hardly local and heritage varieties. I am in the Castilla Leon region of northern Spain. This year many of my young pear, apple, plum and cherry trees have produced unusual spindly unhealthy looking leaves. I cannot find any pests on the trees. The locals say they have not seen anything like it before. I have attached a picture as an example. Is anyone able to help me identify what the problem is? Many thanks. [image]
