How to treat gray leaf spot

I think my problem may be gray leaf spot. I am using Neem oil, but it doesn't seem to be helping. Is there a better fungicide for this problem?

Leaf mold
by: Tomato Lady

My tomato plants have developed leaf mold due to the warm damp or just plain humid weather we've had for the last few weeks. We just got done popping off every leaf that showed signs of the fungus. Now I will be spraying with a non toxic product called Zero Tol. I've had success with this product for a few years now. It is a modified 5% peroxide with a suffactant in it. Maybe the public could use a store bought 3% peroxide.

One would have to adjust the amount of water added along with a drop or two of a mild liquid dish soap. Every year it's something different. Fortunately, when using this product I don't need to be very concerned with what it is because Zero Tol distroys fungus, algie most bacteria and some viruses instantly on contact. It's so fast you can watch it work. If interested and you have a business license I can give you the address.

I only have organic tomatoes so no help here
I avoid pesticides in my garden except for a weed killer Zero which I dab on to the weed plants it takes time but worth it

Bonide Copper Fungicide should work
by: Clark

I haven't had to treat gray leaf spot but I've had very good success treating septoria leaf spot with Bonide copper fungicide. It should also work to control gray leaf spot.
