Not on the allotment - all potatoes and tomatoes on my plot are still fine!
(although apparently everyone else's tomatoes have been blighted out
already!) ... but in the greenhouse! :-(
It's the plant nearest the door, touch wood it's not spreading as of yet.
And it's a fruiting branch, too.

Do I remove the whole plant now, whilst it's not spreading, or can I get
away with just cutting away the affected branch? And how's best to dispose
of? (presumably not in the compost or the food waste bin!)

Dammit, only just getting my first tomatoes ripe, too!

I use "Bordeaux mixture", it won't cure blight but it will prevent
it if applied before the blight attacks.
I've used it for two years now and seems to work.

That's what always happens, it a miracle that the ones on your allotment
haven't got it too. We gave up trying to grow any Toms that were not Blight
Resistant some years ago so instead of varieties like Roma, cherry type etc
we now only grow Ferline, Fantasio and Legend. And, we also spray with
Bordeaux Mixture (copper sulphate and lime) to prevent Blight. Belt and
braces I know but there is nothing worse than year after year watching Toms
get nearly ripe and then losing them all, no crop whatsoever, a complete
waste of all that time and effort.

Regarding your present situation, you need to remove the infected plant
totally and burn it or take it to your Council recycling plant and put it in
the general waste NOT the green waste. Keep a good eye on the remaining
plants and do not get water on them when you water to ensure the leaves stay
dry, Blight needs damp leaves to infect.

Partly due to inexperience and indifference, I once grew tomatoes in my
little greenhouse, and when they started to ripen I just couldn't be
bothered to water them. I had a smashing crop and AFAIK no blight

On another occasion, I had to leave my greenhouse for a few days, so
inserted plastic pop bottles neck down full of water, one by each plant.
The water slowly emptied into the soil ad watered the plants, but nothing on
the leaves

Ignorance is sometimes bliss :-)

Er, no. That is almost wholly wrong.

Firstly, as far as I know, all local authority recycling plants use
high temperature composting, which will destroy much tougher organisms
than blight, even if blight transmitted through dead material (which,
in the UK, it does not). In fact, I believe that there are some
regulations that require them to, because of pathogens that often
occur in food and are harmless to humans.

Secondly, blight does NOT need wet leaves to infect, but high
humidity - not watering may have a secondary effect, but no more.
Even if it did need wet leaves, almost all leaves that close to
the ground are wet in the UK each morning, from the dew, and you
can't stop that.

Thirdly, removing blighted material is of marginal benefit, anyway,
as it overwinters in a large number of common plants and weeds, and
transfers by the wind. Yes, it's worth doing, but it won't make
much difference; spraying with Bordeaux mixture at the right time
will.

That's not a problem in this case, cos it's a growbag. Just have to
remember not to throw it on the ground, and not to grow potatoes in that one
over winter!

Don't worry about it - as I said, in the UK, blight overwinters only
in living plant material.

Bordeaux mixture may not be 'organic', but is just copper, which
is a required nutrient anyway. Unless you go absolutely bananas
with it, there won't be enough accumulation to make any difference.
More effective treatments that used to be used include benomyl,
and that should be kept a long way from all women between 6 and 60.
It's now banned for domestic use.

But if I throw it onto the ground, surely it will then overwinter in any
leftover bits of plant, such as tomato seeds that may grow, or existing
potato plants that tend to hang around in the flower beds.

In fact ... surely if it's a fungal disease, it will happily hang around in
dead bits of leaf, etc, and will resurface from that? I'm not sure i follow
why it wouldn't.

Is it available to buy? Nick was under the impression it was one of the
limited or removed availability products. (My Nick, not you :-)

Blimey, that's a bit ... kind of specific, but also non-specific, if that
makes sense! What does it do? Some kind of hormonal imbalance mutatey
thing?

Humph! I've just suffered a total loss of my tomato crop as a result of
two days very humid weather at the beginning of this week. At least, it
took the humid weather to bring it out. First time I'd grown tomatoes
for many years and someone gave me the plants otherwise I wouldn't have
bothered. They came on beautifully and, a week ago they were looking
fine. Then came the humid weather and within a day they were looking
sick.

Not being in the habit of growing tomatoes I didn't realise that a dose
of Bordeaux mixture before the event would have helped, of which I have
plenty (I buy a kilo at a time for regular treatment of my vines). I
tried spraying as soon as the blight appeared but, as most of you would
have told me, by then it was too late. At least with vines, if you spray
*immediately* any sign of mildew is apparent, then you can just about
get away with it. Not so with tomatoes/potatoes, it seems.

Ironically I have had no sign whatsoever of vine mildew this year!

Tbh, I don't /normally/ have a problem with it, but I also don't normally
put tomatoes on the allotment. I just thought it was a good way of getting
rid of the last tomato plants that didn't sell in the summer.

A-ha! Nick says it's his fault, cos he's been using the sprayer hose and
spraying the leaves. Lesson learnt!

I forgot to post this. Try Tuckers - I can strongly recommend them.

No, I've seen it in all the GCs I've visited lately, sold under the Vitax
brand. It washes off the fruit. which is why I went and re-applied it
yesterday. Organic? No idea but it used to be in an Organic Gardening
catalogue I used to get. It's a powder, but whilst you can puff it on it's
much better to use it in a sprayer, instructions on the plastic bottle (can
be difficult to wet initially).
If you can't find any it's probably because they have sold out. We buy it as
a matter of course during the winter.

Are you sure it is blight? It might not be.
You will most likely have more experience than me and know if it is or
isn't blight.

I have many problems this year with the tomatoes and most of it is neglect
by me with other pressing issues.

What I have done is take off the dodgy looking leaves/foliage and all
sideshoots and give them a good dose of tomato plant food. Within 2 days
they look like they ought to be in a show, foliage wise.
I hope the fruiting follows suit. I know it's going to be a dodgy crop with
the intermittent, or irregular care I have given them this year and many of
them will split or get end rot.

Nick is now undecided about /all/ of it being blight, but I'm pretty sure
that the first plant is (unless I've been mistaking something else for it
for many years!!), which maeks it quite likely that it all is, I guess.

Well, I am not an expert by anyones imagination, but from your origional
post you say that in your greenhouse you are only just getting ripe
tomatoes. Could it be watering/feeding or lack of? Ventilation? Not blight?

I have one of those crappy little polythene greenhouses with 3 Gardeners
Delight plants in and have had tomatoes from June.
The rest are outdoors and have been neglected but still have had tomatoes
ripening, not many but they are there.

If it were me in your situation I would take off the best trusses and put
them in a dark place, a drawer to ripen and take off all the affected
leaves on the plants and see what happens. What have you to lose, now you
are convinced it is blight?

Whichever way I hope its going to turn out right for you.
