Black Spots on Tomatoes

Can anyone identify what is going on?

did you get hit with hail? that doesn't look like disease to me.

Looks like a worm took a bite, and now it is starting to rot around the damage.

My suggestion is typical anthracnose which happens for many when the nights start getting colder and/or late ripening fruits..

Look at the concentric circles inside the lesions you show,which is typical of anthracnose.

Agree, that looks like anthracnose in the third pic especially.

I have anthracnose on one plant. Bad too, I should call the darn thing. When I see it on supermarket tomatoes I know its been there too long for me. With regards to the blemished unripe fruit, I am guessing it is critter damage. Is there any outward sign of anthracnose on unripe fruit?

As Carolyn said, the concentric circles of spreading damage suggests anthracnose -- but my first thought on seeing your pics was that you might want to also do a search for tomato fruitworm.

Two small dark spots, formerly worm-entry-door and worm-exit-door. (Unless more than one attacked the same tomato.)

By the time you see two little spots like those in your pics, the worm (caterpillar -- baby moth) is long gone.

Might be both -- tomato worm then anthracnose establishing at the wound site -- but when I've seen it, typically there are nice looking fruit with just those two small spots . . . and inside the mess the worm left behind while in residence.

It's frequently said that they enter at or near the calyx, but in my experience -- and in pics a search should find, they enter wherever they want to without a lot of preference -- but usually just two spots (unless more than one worm was present). Conspicuous surface damage beyond the entry and exit dots is rare, here. Perhaps entry spot and secondary infection liklihood varies with climate or time of season.

Fortunately, while they often get a few fruit, the parent moths must be rare, here, (thus far), as they don't normally attack too many.

Anyway -- might be worth checking -- if you do a search for some tomato fruitworm damage images you can see if they match what you're seeing.

Much empathy, anyway -- it's so frustrating to see nice fruit destroyed.

It looks like worm damage to me too. I am seeing some of it in my garden too and I have actually seen a couple of worms.

From the first picture, with green tomatoes, It seems that it was a worm hole and subsequently started rotting as the air got into it.
If you a cut through the spot it might show something.
