Shot hole is usually bacterial spot which is a bacterial disease that few sprays work well on. Myclobutanil is a good spray for many things, but not for shot-hole. Re: the all purpose fruit spray, nothing in there really helps against anything. The best spray for shot-hole is copper at leaf fall and again in spring just before leaf-out.

Your curling pear leaves I can't tell for sure what is happening. That is often caused by aphids so I would look for aphids in the curled-up bits. Your all-purpose spray may actually work on that, aphids is one of the few things such a spray will be good for. There are several other causes of pear leaf curling besides aphids.

I had read some where that shot hole could also be due to fungus and given the wet weather we have here, I thought
that would be the most likely cause.

I can give copper a shot at leaf fall since it is too late now.

I did not see any insects on the curled pear leaves. For now,
I have just removed & disposed the ones that looked real bad.
