Can anyone identify this?
The heirloom variety is Livingston's Paragon. I have been dealing with tomato pith necrosis. Is this brown line travelling up the stem just another symptom? The plant has 2 stems. The other stem doesn't have this. Any ideas would be appreciated. LOL I must say that many tomato diseases appear to have very similar symptoms. It's getting late in the season here. The plant has given me fruit so I can't complain. I'm just trying to get a "heads up" for next year. Thanks
