Hi. I noticed today that the pears on our pear tree are diseased, seem to be shriveling up, look mottled and have black areas on them. I'm confident they got pollinated. We have treated the tree last fall and this spring for pear blister mites which we had last year and then we also had to treat it for green worms eating holes in most of our leaves this spring. We've used neem oil, insecticidal soap and another treatment for the blister mites problem that I cannot remember the name of. Not sure if any of those things could be the cause of the problem or if it's yet another problem. I've attached a couple photos. I know they're not too good. Let me know if you need better photos. Thanks!
