Bacterial leaf spot in tomatoes?

Asked June 29, 2018, 10:50 AM EDT

I think I have identified the problem but wanted confirmation if possible? I believe this is bacterial leaf spot on my heirloom tomato plants. If so any recommendations for an inexperienced Gardner?

Tomatoes are susceptible to several leaf spot diseases. This looks like a fungal disease, septoria leaf spot. On leaves that already show symptoms, a fungicide would not be effective to control or clear up the problem. The best you can do is prune out the symptomatic leaves and discard them in the trash. See the following page for additional information on septoria leaf spot and how to control it:
