What's causing this Tomato rot on the vine??? :(

gssgarden · June 22, 2015

Any ideas? Just seemed to happen to a couple of Shannon's and Anna Russian. There is a plant between them.

Bug?? No signs of stress at all. Plants look good considering the constant 99 degree heat lately!

Any ideas?

Thanks!

Greg,

Not seen this before - but appears to be nasty. Looks like entire branches have died as well. Have you considered pulling those affected plants before it migrates to your healthier plants?

Hopefully, others here can give you their expert advice.

I can't see your pictures well at all, just a little bit in the third pic. From my screen it looks like you have black around the bottom of the tomato. You might google different places and try matching up pics of Black Mold with what you have.

edited to add try googling Black Mold on tomatoes, so you don't get hits on other plants.

The bottom pic looks like blossom end rot.

Did you cut open the rotting fruit to see what's inside?

I've been getting a few of these,too. I kind of thought it was a combination of sun scald and extreme heat, since we've been high 90s and low 100s for over two weeks.

It is just BER (blossom end rot). It is in advanced stages because the fruit was left on the vine far too long and continued to rot rather than getting pitched when it first developed. In the last picture the green fruit next to the one you are holding has it too and should be removed now.

Once BER develops in a fruit it can't be stopped so no reason to leave it on the plant. Plus you have several dead branches showing in the pics. Why are they still on the plant?

Dave, it didn't act like BER. It just happened, quickly! Those dried up leaves have nothing to do with it. Just broken branches while tying up a few days earlier. Other wise, the plants are tall and healthy!!

Sometimes BER sneaks up on us overnight. Other times it seems to happen quickly when in fact it was there all along and we just didn't see the beginning small blotch. As I said the green fruit in the second pic next to your thumb already has it. You can see it in the pic.

It looks like BER and it is paste fruit very prone to BER, but look at it from the process of elimination -it is not Buckeye Rot, it isn't Bacterial Canker, it isn't Late Blight, it isn't Anthracnose, it isn't Black Mold, and it isn't TMV. None of those symptoms on the plants themselves. So what are we left with?

BER.

No I know the dried up leaves in the first pic have nothing to do with the BER but they appear to have been dead and dried for some time. And in the second pic there are yellowing leaf tips and a couple of leaves with yellow and brown patches that could be indicative of other problems as well.
