Checking on the garden this afternoon, I found brown/black spots on the lower leaves of my tomatoe plants. I think it's either bacteria spot or bacteria speck. Either way both can be treated the same..at least that's what I found on the web. From the Kansas Status University Extension site:
"Copper-based fungicides, including basic copper sulfate, copper hydroxide, and copper resinate, may be effective in suppressing bacterial speck and bacterial spot. Make applications at the first sign of leaf spotting or at the time of first blossom. Continue applications at 7 to 10 day intervals."
Now to figure out if any of that is organic, and if not then what is that can help control it.
