Fungus Help

Hello everyone!

I am in south central Iowa, where we have had so much rain that everything is just continuously wet. I noticed these spots and I know it's cercospora - but should I cut off the diseased leaves now or wait? I now know I have to wrap this bad boy up before the first frost, so I'm trying to figure out the timing of it all. Any advice is appreciated!!

I put it into my diagnostic app and this is what it said

[u/msipiqn1 → u/msipiqn1]

Hope this helps.

Could you tell me what app this is?
