Same here, blight just hit my tomatoes - you can see the first plant in the pic below. Spent all day long yesterday trudging back and forth with bags of tomatoes, washing them, drying them and laying out to ripen in trays (hopefully!)
Shouldn't really complain though, this is the latest date the blight has hit here in six years.

Not a pretty sight!

I had to pick all my tomatoes on Wednesday, but I'm now wishing I'd picked them at the weekend as I'm pretty sure that I'm going to lose most of them to blight. Last year I managed to pick them just in time, not so lucky this time!  Never mind thought, I have at least had some :-)

If you wish to be organic (or as near to organic as possible) you can use Bordeaux Mixture (which is basically a mixture of copper sulphate & slaked lime) or one of the several proprietary brands of copper sulphate sprays. The effect of these, unfortunately, only lasts until the next shower of rain, when it has to be repeated.

If you are prepared to shelve your organic principles for the sake of your potatoes (or tomatoes, for that matter) you can spray with Dithane 945, which is systemic, and the effects of which last for 10-14 days whatever the weather.

I would like to vouch for the Bordeaux mix.  I have used it religiously the last 2 seasons and have had amazing success, and although finally there was what I thought a touch of blight showing, I now just think the plants are dying from exhaustion!  Today I filled another bucket with lovely toms.

It may be accepted by the organic fraternity, but I won't put heavy metals into my soil.

I've seen Bordeaux mixture in available in orange bottles, do you have to
mix it with water and spray it on or is it some kind of powder that gets puffed
onto foliage?

Best as a spray - @35g/1.5l. Use immediately & spray under & over.

If you want to dust, you need a puffer thing.
