Well actually 'frogeye' is a leaf disease on apples actually. It looks like that though and it is the time of year for it. It might not be called frogeye on peppers. Well actually it kind of is:
Frogeye leaf spot, caused by the fungus Cercospora capsici, has distinctive symptoms on leaves, stems and peduncles of pepper and eggplant. Lesions are circular or oblong, tan in the center and sur…

A quart of 3% H2O2 per gallon is 0.75%. Hydrogen peroxide can actually be quite costly to use in my opinion but can work on some things.
I've never used neem or BT so I don't know. Other members use and recommend the stuff on certain things and their word is good in my book.
Regular is what the label says. I use chlorantholanil on my peppers and dont have ANY leaf problems on my peppers. I use that about weekly. I think of using chlorantholanil to the same as using 'Armor All' on your tires. It puts a layer of protectant on the leaf that can be washed off by rain or by the growth of the leaf stretching so you have to take that into factor to the application times.
Heat is one thing, but the humidity is another. Humidity makes fungi thrive regardless of the temp.
When I see a leaf with suspicious markings, or a new-to-me bug in my garden, I take a picture and Google it. That's helpful with identifying bugs. It's absolutely worthless when I'm trying to identify a plant disease. They all look so alike to me. When I Googled my pepper leaves, I found “Bacterial Leaf Spot” and thought...”That looks like it”. Then I clicked on your frogeye link and thought...”That looks like it”.
So chlorantholanil protects pepper plants against fungal disease? Does it protect other plants, as well? I'm in my garden several times a day, but I mostly wander around aimlessly wondering what to do. I have the time to incorporate preventative measures, the willingness, and I've even backed away a bit from my initial strictly organic mindset. But none of that matters when I don't know what the heck I'm doing.
I'm also reluctant to admit how small my garden is, lest “small” translate to “inconsequential” on a gardening forum where posters probably have acres to worry about. But my two 4 x 8 raised beds, and the 7 containers I added this year are hugely important to me. I have one pepper plant in a container and one in a raised bed.
If someone were to ask me today how I like fabric containers, I'd have to say “Not one bit!” I get a modest flow on my hose, stick it in a container, and within a millisecond water is flowing out the sides. It doesn't flow out the sides after the container is soaked good, it flows out instantly. So how soaked the container actually ever gets is a mystery to me.
My container pepper had three peppers on it. And when I picked one, I saw a disease I do recognize. Blossom end rot! My plants have never had BER and I thought only tomatoes got it. To my surprise, pepper number 4 had no BER. Then we got two huge rain events back to back, and I counted 13 little bell peppers dangling on that plant in like a day! I couldn't believe it. No idea if they will have BER, or not.
Now I keep a milk jug with a few holes to drip water in it continually in hopes that's a good idea.
Anyway, thank you. For taking the time to share a link, your experience, and your problem solving!
