That doesn't look good... so sorry!

What do your plants/leaves look like?

[pipefitter508]

I have been removing all the bad leaves some plants are striped of all leaves
The 4th of July, New girl improved and burpees big boy are doing great
I am getting enough tomatoes for the vegetable stand
We have had a very wet July along with 90 dg temps and now very cool nights 48dg
I have started picking as soon as I see a bit of blush

It looks like you've got Botrytis cinerea (Gray Mold). Are you getting gray mold on the stems and leaves too or are you getting other diseases that are defoliating your plants?

Here are some other pics
Where I striped all the dead leaves i had to cover the plants with my shade cloth I use for my greenhouse 's i was getting sun scaled

Wow. Not sure what to say. You are in Mass. ?
Clearly you are experienced with such a good set-up.

I think RayR has it with the grey mold.
I get it on one of my wine grapes 3 out of five years and this year it is here once again.
Not the same but similar favorable conditions that this particular variety does not like
the fluctuating heat/hot/humid conditions along with damp soggy dewy mornings.

Confusing it is so rampant in your garden. And others look great.

I am in mass near the providence R.I line
Last year we were in drought this year we had a very wet cold spring and early summer then a 2 week heat wave heavy rains
Now cool nights lots of due in the more hot humid day temps
Last year I was out of tomatoes buy the second week of August
This year there just starting to ramp up
And I was in the ground April 28

acid rain
I swear the tap watered plants do better than the rain watered.
I should take ph readings.
I have plants that got wiped out before they even made it into the ground.
I had seeds I started late and the plants were still in trays/potting soil and they croaked.
The sad ones were the sungold @ 35cents per seed.

Bob saw this earlier.
Cut the rotten places out and make salsa.

I'm seeing a fair number of yellow leaves and I'm not sure if that's a symptom of gray mold or not. Just for the heck of it, if you have a plant ready to be pulled, cut diagonally through one of the main stems a few inches above the soil line and look for brown streaking in the inner tissue. I hope you don't, but those yellow leaves are concerning... I've seen way too many of them over recent years.

I think that you should have started doing something a bit earlier, like spraying some antifungal. And those plants are rather crowded. It's gonna cause problems in a wet year (which it already has). I can't really tell from those pictures what it is, but RayR is most probably right about the gray mold, considering also the fruit symptoms.

I agree with Gray Mold. You can check here http://vinesgardens.org/wp-content/u...-Disorders.pdf for a good description of this condition. Copper, daconil and bleach are a good way to control it if you start early.

[pipefitter508]

Thanks everyone for your help next year I will be taking early preventive steps
Are the above prevention consider organic ?

Copper is 'organic gardening approved'. Not sure about bleach. Daconil certainly not.

I did see some gray mold on some of those plants but you have other problems as well. I agree your plants are way too crowded for a wet season. You might get away with that in very dry conditions but not when the humidity is high and with lots of rain. You could also have some form of soil born disease as well as some pests like mites or whiteflies increasing your problems.

I know that copper is considered organic and I believe bleach is also approved for some uses in organic gardening but I'm not sure. I know too that you have waited very late to start treating the plants but it may not be too late. Besides removing the diseased leaves you might consider removing some of the stems and maybe a few plants that aren't doing well just to allow better air flow and sunlight.

If you have enough rain that kind of rotting is not uncommon as I see it every year that we have lots of rain and this year has been one of the worst for that problem down here. We have only had a few days without any rain at all the past two months and it has created real foliage and fruit problems for me also. I have sprayed with the diluted bleach spray, copper and Daconil in an effort to keep the diseases under control. I have also made a lot of salsa and put a lot of those tomatoes with those rotting spots in the sauce pot. Rainy conditions mixed with hot weather will create conditions for all kinds of problems with tomatoes.

Good luck.
