The fruit itself - again what is the variety name? please include that info in your posts - is yellowish (is it supposed to be yellow or not) and shows signs of BER so likely should have been picked and pitched long ago.

Splitting is normally due to water issues of some kind but in this case given the location on the fruit it looks more like cage damage, perhaps from heavy wind.

The plant as a whole is in bad shape and looks to have going downhill for some time. It needed an intervention some time ago. It could have been EB or Septoria or grey mold or any one of several other diseases. But in such an advanced stage of decline it is impossible to ID what may have started it or what clues the leaves might have given a couple of weeks ago. The classic leaf symptoms of the common diseases that we use to differentiate the diseases have long since shriveled and died.

The only real clue in the photo is the yellowing of the stem sections I see and the fact they are yellow and not black. So if I had to bet on what the original problem was I say the odds favor Early Blight with some nutritional issues thrown in.

Sorry I can be more specific but at this stage the plant is a lost cause.

Looks like the birds took a few bites out of that tomato, or some other animal.

As for the leaves, looks like russet mites, or possibly spider mites

dig dirt, you are good, the plant did have BER.I was told to leave it alone and it would go away and the tomato could be eaten. I was waiting for it to turn red.Plant produced good eating tomatoes but have been scarce and it seems to me that it takes a long tome to mature. IF YOU LOOK AT THE PICTURE YOU WILL SEE (SORRY FOR CAPS) a green one trying to turn red. Hope its before the cold weather comes.

fungus thanks for the input Ill follow up.

BER will usually go away in later developed fruit but not in fruit already showing the symptoms like this one is. Plus leaving BER fruit on a plant only stresses the plant more and wastes plant energy. The standard recommendation it to pick and pitch them as soon as you see them.

Same goes for all that infected foliage on the plant - it should have been removed as soon as the first symptoms appeared.

And eating BER fruit is questionable - most won't as it has a very bad taste.

No idea where you live but there is a lot of season left before cold weather for most of us. It's unlikely that plant will survive long enough to ripen that single green fruit (trying to turn red?? not from the photo). Rather whatever killed the plant will likely rot the fruit.

I don't think they taste bad, .I salvage what i can.Still looking the name tag it was buried in the dirt. Poor planning beginners mistake.
