That looks like tomato anthracnose a soil-borne fungus disease, not severe in your pic, rainy areas are not good for it but good cultural practice such as not watering from above, not much help in rainy areas, and also mulching, looks like you have that covered. I had it once and it never got much beyond what you have and only on a few ‘maters. Still good eating though, just cut the bad part out.
Google or whatever it.
Thanks. We had two rain storms totaling 11in. We do water through a drip irrigaton system that is under the landscape fabric. We had a lot of this in Mobile where it rains every afternoon in the summer.
Thanks again for your help.
