    One of the tomatoes I harvested when culling my plants on Friday has an odd appearance - is it botrytis?

    It is the only one that seems to have this effect, although there were a couple of fruits that I ditched that were completely brown and rotten looking which were tucked away at the back of the plants.

    I take it that this fellow should be lobbed?

    I don't know much about growing tomatoes - I had a miserable crop this year. But I did have some similar tomatoes as yours but mine had more of the black spots. I wondered if it could be Bacterial Speck. Hopefully someone with more knowledge will enlighten us.

      I'd say it probably is botrytis , think the spotting on the fruit itself is also botrytis based.
      Ghost spot.

      Anne black spots are possibly blight.

      It's not the sort of Botrytis I normally get, usually it's obvious with a grey fluffy mould on the stems and leaves and the fruit go all mushy, and once it starts it gradually gets into all the plants. If it's only one or two fruit just bin them and don't worry, there's so many things it could be.

        I agree. Botrytis is usually fairly obvious, as John said...

        Thanks :)

        It might well explain the mouldy leaves that I had on most of the plants though.

        Botrytis is a real problem for me every year around this time, I keep on snipping off any leaves showing symptoms.

        I'm wondering if it all started earlier on in the year in the polytunnel as I had quite a lot of leaves rotting and falling off even back then.

        Good find there pete. From that web page:
        "Ghost spots develop when the fungus initiates infection, but disease progress is stopped by adverse environmental conditions.This spotting may adversely affect market quality. A change to favorable conditions allows Ghost Spot to proceed to fruit rot."

        Aye, looks about right to me. I was watering in the evenings mostly, humidity in the poly was high, air flow was poor and this particular tomato was on one of the plants that I ditched out of the polytunnel into the great outdoors which appears to have stopped it in its tracks. Oddly enough, the leaf rot/drop also pretty much stopped as soon as I got them outside too.

        I take it that its inedible then?

          Thanks pete! :dbgrtmb:

          I've got a load of others ripening in my home made ripener - Help! Off-plant ripening - and they will probably end up in a tomato sauce to freeze and use for curry or pasta etc, so it can join them :)
