Safe, organic treatment for Septoria?

13 years ago

My tomato plants have Septoria leaf spot. Removing the affected leaves by itself doesn't seem to be halting its spread, even though the weather has been warm and dry. I'm very reluctant to spray with a chemical or copper-based fungicide, but am open to remedies such as a baking soda spray, etc. Or I could continue removing spotted leaves, harvest what I can before the plants are defoliated (and hope the fungus slows down by itself). I'm also considering rotating out of tomatoes (i.e. not growing them) for a year or two to try to rid my soil of the spores. Can anyone offer advice?
