spotted leaves, browning stems, bacterial spot?

12 years ago

Hi Tomato Experts,

Well, I threw out three transplants early in the season because of spots on their leaves. I kept the ones that had no spots, but now they are developing them... any idea what is causing this and how to deal with it? I have been spraying with Serenade as a preventative, once a week. It has caused some minor leaf burn, but nothing major. The spots are limited mostly to bottom leaves of 2/3 of my plants except for Stupice which seems particularly susceptible. Otherwise the plants seem in good form. Sun Gold seems unaffected. Some of the spotting has migrated to stems. Please see pictures below. Any and all help will be greatly appreciated....
