Some some my tomatoes are sort of shrivaling and rotting in on themselves. Forgot to take pic, but it's not like a spotting rot, but more of a collapsing in/oosy rot and has a wrinkly look. Any thoughts??

Too much constant rain causing cracks and rot pathogens getting inside?
I have been picking mine at first blush all season to prevent cracking or other damage. |

Very hot and dry, then wet, humid, very hot for weeks in the NEast. Texas heat.
Usually still harvesting beauties but this year all is about over but a few dozen holding on. Not exactly what you are describing but I've picked a few the past week that went straight to the compost. I did expect it seeing an exterior dark spot. |

It’s the same problem as blossom end rot, only it’s internal.
Same causes. KarenO |

Your location gave it away it for me. There's too much rain happening there in PA this year. What Oakley showed in the picture - I also saw here in 2015 when it rained way too much.

It does indeed look like ber. When there's a rot but doesn't spread around like you'd expect, it's something that happened when the tomato was immature (like ber)

It is Internal blossom end rot. Rather a misnomer because it’s not really rotten and it’s not on the blossom end but nevertheless that’s what it is. KarenO |

Correct, it is Internal Blossom End Rot.
In most cases the rot usually forms at the base of the columella, the weakest part of the tomato, but not in this case. |

Well if it is internal blossom end rot and is caused by uneven watering and stress we certainly had those conditions in PA this year. We had unending rain except for when we had blazing heat and high humidity.
My tomato harvest was about 50% lower than usual but I picked most of my tomatoes at first blush and brought them inside to prevent cracking or predation by insects or animals. This is the only way I was able to have a decent harvest this year. I am also glad that I use tall tomato cages because it gave the plants good airflow and helped them to dry off. |

The causes of external BER and internal BER are very different.
I tried to find to find the article that Mike Dunton at Victory Seeds asked me to write Well I found it,at least the first version and amended it to discuss internal BER as I recall \\http://www.webgrower.com/information/carolyn_ber.html Internal BER occurs when not enough calcium makes it the blossom end where one can see the typical external symptoms. One can't see internal BER until the fruits are cut open. Maybe this might help as well https://www.google.com/search?q=inte...&bih=788&dpr=1 Carolyn, hoping that the links work since I can't see that when previewing a post.Mike was generous in saying I'd grown 1000 tomato varieties but that's up to about 5,000 by now. ![]()

Don't know if your answer is scientific, but I think you got the closet. Definite outside visual signs of rot and it seems to be starting around the cracks. Thanks all. Found this pic on line and it is as close as I can get.

What I see now in your picture was mentioned above,I see splitting opening a huge fissure,that has allowed probably one or more species of fungi,or even yeast to colonize it. Lots of different bacteria,fungi,yeast,etc.in the air Due to rain. Stop the rain,ahem,or over watering,if that's happening as well.And as the rain falls the bacteria,yeasts, etc,become trapped in raindrops that fall on your plants. If no surface wounds on the fruit,not a problem,but if any open wounds,that's the problem. How many plants do you have out there and which varieties are showing those symptoms more often than others.? Carolyn
