I really need an arborist, but I can never forgo a Seinfeld reference:

I sprayed my apple twigs a couple days ago and now I've got black spots. At first I was like "I think I sprayed them with Round Up. I'm going to kill myself", but I've got a sprayer dedicated to only tree spraying so unless I bought the wrong stuff or measured wrong I know that couldn't be it. I re-read the package and know for certain I measured correctly so I think I can forgive myself. I'm starting to believe it was a gift from a late Spring frost.

Here's a picture of a leaf

And here's my daughter taking a picture with a Ipod and a microscope. Notice the bruised cell structure.

And the edge of a ripped leaf with the guts hanging out.

Ha I like the reference. I actually have a B.S. in bio, though I focused in micro bio/bio chem(and it's been a few years). At first glance it looks like fire blight or apple scab, but I'm not an expert, and a lot of these diseases look very similar when they start. If it was fire blight there would probably be a canker on the bark somewhere. If you google apple disease pictures there are a lot of good web pages, I find state universites have the best.

Could also be frost damage, or a disease that took advantage of the tree's weakened state after the frost.

Unfortunately I don't have any experience treating these diseases, but there are a lot of handy people on these forums that probably do. Good luck!!
 
it just so happens i met a real full fledged marine biologist today! and he also happens to be a hearth.com member (how bizarre is that!) hahaha.... his name here is Defiant

read about my road trip to meet him here https://www.hearth.com/talk/threads/road-trip-today-to-meet-a-great-hearth-com-member.86559/ then PM him to see if he can help (i know he is headed under the Tappan Zee Bridge this weekend to do whatever the heck biologist people do but maybe if you PM him you can catch him today!

Looks like golf ball damage.

I'll be certified to be a wildlife biologist in December, but it's not December yet. And plants don't have legs or even fins.

However, every time I've used glyphosate the affected leaves did not do that. They went limp and shriveled up while staying green.

Re: the Tappenzee bridge, he might be working on the replacement of it that is scheduled to start next year. I can't imagine the permits required to do the job.

Need to spray with an adelgid type detergent (used primarily on Hemlocks), I have an apple tree and I have not bothered to spray because the deer eat all the apples. Just my .02.
