Paw Paw Black Spot Disease

This year my paw paws seem to have black spot disease. Usually the black area starts where the leaf attaches to the branch and fades from there, although some leaves may have light spots. I sprayed with lime sulfur but I think I may have burned some of the leaves. A week to 10 days later sprayed "spray oil". I was thinking of spraying at 10 days with sulfur (no lime)- or maybe Serenade? I am also picking the leaves off the plant when I see the black spots. Would appreciate any information you can give me. Both of my paw paw tress have it although by Overleese has it worse than Sunflower.

On another note, I have a solitary banana plant where I had both Basjoo Musa and an ice cream banana plant. My Basjoo has a dripping fat yellow bloom. The bloom from this banana seems narrower. Thinking that if the blossom is red or different then it could be an ice cream banana plant. Anyone grow any other bananas aside form Basjoo? If so how did the blooms differ?

I have never seen or heard of this disease before. Maybe I should read up more on my diseases.

I found this for Bordered Leaf Spot on NA Pawpaw:

I've not experienced this, but reading the article, what caught me first of all was that wet/humid spring, dense foliage and lack of air circulation are contributing factors. Suggested pruning to correct, I think that's where I'd start. I, so far, don't have the patience to do the necessary research and reading of the spraying products and protocols that it takes to apply such things in the responsible method or manner.
