There are a number of rots which can effect fruit.

Based on your weather I would suspect that is grey wall.

Sometimes BER can be internal only.

Cut a fruit in half and take a picture.

It is not BER; But you might wish that it was. IT has a resemblence of Early Blight. If this is an isolatated incident just watch for more problem leaves and fruit. A preventative fungicide spray would be warranted (between the raindrops).

Bill,

It could be side wall BER or some other fruit rot. The environmental conditions you describe are conducive to Early Blight (which we hope it isn't). Have you noticed dark brown spots on the leaves or any stem issues?

Good luck.

Hi Bill, have you considered Buckeye Rot?

Here is a link that might be useful: TAMU Help

Bill,

I've noticed the same thing on a few fruit and live fairly close to you and have had lots of rain as well. But those spots on the sides are exactly what I have seen on a few fruit and wondered what was causing it. I've not seen it on the side like that prior to this year. I also have BER on the bottom of some fruit.

You guys are having the weather we had last year. I say its BER with a twist of mother nature..

Bill you make the best detailed posts ever when you are asking a question...:)

Doesn't look like BER to me.

The good news is that your plants look good and your rains are stopping. Good luck...

It doesn't look like BER to me either.

Wow! Thanks everyone for the great response, and so fast too. Other than that, it just ain't been my day, the batteries fell out of my camera when I went to put the chip back in and I lost my date and time settings, could not get a decent picture showing detail on the rot after cutting that tomato in half etc.
However I do really appreciate the response and here is some further information.

is the best shot that I could get of the tomato, and I do not know if it is good enough to reveal anything more. is what the leaves look like (I wonder if it is Septoria leaf spot), but the good news is that there is no indication thus far of any problems with any of the on this plant or any of the others.
Perhaps that will help the investigation.

I changed my mind. Its not BER. lol

Bill you are the very BEST ;-)

You have had a work out, oh, before I forget I thought I saw another ripe one in the beefsteak pic. ha

I too doubt that your soil is lacking calcium but keep in mind it's the uptake by the plant that has an impact on the fruit. What have your low temps been like? Anything in the 50's since the plants have had fruit? Water soaked roots?

I know you are a big part of the GW forums but am thinking maybe you could bring this (the cut tomato) to your local aggie and get their take on the problem?

Let's all hope it doesn't lead to world hunger!

Good Luck,
and I know you will keep us posted.

Could it be an injury that ocurred during one of the storms we have been having , since it was touching the stem , a bruise maybe???

Thanks Gumby! ":^) Thus far, there is no indication that it is spreading, but if it looks like it will reach those proportions, I will get out my flame thrower and annillate the whole patch. The damaged part is already in my compost bucket under the sink and the "good" pieces are in a zip lock bag in the fridge to see if they will go ahead and ripen, I may take them out of the fridge, but that might hasten their rotting, being in a plastic bag.

Possibly CDGTXS, the tomatoes were resting against each other and were positioned to where they probably held a few drops of water long after every thing else had dripped dry. I have shook the cage vigorously and have noticed some slight marks on some that were resting against the wire of the cage, but do not think that these two had flexibility to allow movement to bang against each other. If it is not something that might be a result of the leaf problems, I am beginning to lean toward the grey wall rot. It also resembles the Buck Eye Rot that Trudi posted a link to, except that I saw no evidence of any concentric rings in it.

Gee Wiz!!! You got bumped into page 2 already G-Fish.....
I was gona make a comment wednesday night, but got tied up, and now here it is Sat...So many posts ago, let me put ya back on page 1 my friend

I have been battling BER again, Ive tried everythang in the world to get it right, but seems like theres gona be 1 or 2 that get it. My Arks, Cherokee Purples, and some on my Better boys. I did notice less of it this year since I started tillin in the Epsom-Salt, but anyway were finally pickin Maters Woo-Hoo! and keep on a growin Good Gardenen to Ya!-Blane

Thanks Blane. That is the only problems thus far and I am looking forward to it being a good year. We should all get plenty of tomatoes. It looks like our weather patterns are changing and the rains are letting up some.

You are probably about like me and have a few early in the year. each year, that goes away after the weather warms up. I have only seen one small tomato that shows some cat facing (a different problem), but none that looks like the typical BER so far. The only ripe ones that I have had so far is a few of the cherry tomatoes, but many of the different varieties are loading up with little tomatoes pretty good.
Regards and good gardening to all of you.

Hey G-Fish! Not to change the subject....but, Has your neighbor got the SVB yet? ouch!

Can't say much for Texas gardening but I noticed something in the pic and you said so yourself that your plants were touching. I give my plants 4 feet in all directions and cage mine as well to avoid touching unless they are bush variety. I am by no means an expert and you could have space limitations but to keep the disease from spreading you might go at least 3 feet next year.

Take care and God bless,
suterstomatoes

Who cares what it is... It'll probably clear up a little later. In the meanwhile... OMG! That's gotta be the most weed free garden that I have ever seen! Good work, my friend!

Bill,

That almost looks like a powdery mildew on the leaves. I think I wouldn't take any chances with it and yank it out of there. Better to lose one plant than the whole bunch. Hope you figure it out soon and come to a solution.

Bill S.

Bill been surprised someone didn't blame it on the rust on the CRW cages. I've seen them blamed for about everything else.LOL. Your garden looks great and hope it only affects those two fruit. Looks like a rot to me. But nothing I've ever seen for sure. Great gardening and keep us informed. Jay

Thanks Guys. Not that I can tell Blane, I have not seen Tom out in several days, grass and weeds are

as you can see. You can tell the difference in the yellow crook neck squash plants in the foreground and the Zuchinni plants beyond. I was worried about Tom so I called him to be sure that he was up and around, and was relieved that he answered the phone and seemed in pretty good spirits.
Those SVBs may just not be able to find Tom's plants in that jungle, or it might be that the unusually wet weather drowned most of them.

Thanks for the suggestion suterstomatoes, but I just do not have room to spread my tomatoes out that much, and generally have had good crops.

Thanks Brian, like you, I think that with the abrupt change in the weather to hot with some wind, things will change right away.

Bill S. I don't think that it is powdery mildew, the plant may lose most of its leaves but it is loaded with good sized tomatoes and I do not want to lose lose them. The cutting that I took from the plant has rooted and been put into the ground, seems to be doing fine.

Thanks Elkwc, I hear you on the rusty cages ":^) Wouldn't surprise me either.
