I still need help with the fungus on my tomatoes.
One plant, a Beefmaster, was dead by first of Sept. All others, except the cherry tomatoes, were half-consumed by season end. Cherry tomatoes only slightly.
What else can I do?
Any suggestions will be appreciated.
Sorry, not sure what happened. I possibly hit the wrong button.
Plant diseases are sometimes difficult to diagnose. When a plant doesn't respond to a treatment, there may be resistance to the treatment or more likely the diagnosis is incorrect. Brown edges and stem lesions on the plants seem to indicate that this is a bacterial problem. Most likely this is bacterial canker; however, the spotting on the fruit is not evident. Pathogen source can come from seed, weeds, plant debris, transplants, etc. (see links). Crop rotation can be a big help. Other bacterial diseases could be suspect. Although bacterial canker is hard to treat, for other bacterial diseases, a copper-based fungicide (also a bactericide) can reduce the progression of the disease. It could be the photograph, but the plants look like they could be shy on some nutrients. A soil test should answer that question. Check out the following links:

Again, sorry for the delay. I hope this is helpful.
