The only thing to do with tomato blight is to bin the lot and not on the compost heap.
The French use a purin/tea made from soaking bruised horsetail stems in water for a couple of weeks and the straining the resulting liquid - as you would with home-made nettle or comfrey tea for fertilisers. The resulting tea is then diluted and sprayed as a funficide on fruit and veg in spring and autumn as a preventative but can be used all summer if needed.
1kilo fresh horsetail 9 litres of water
Combine the two in a plastic bucket - not metal - and leave for 2 weeks. Stir occasionally. It's ready when the water has gone black. It will smell so you may want a lid.
Strain the resulting liquid, put the goo on the compost heap and dilute the rest 1 part to 9 parts water and spray. Not harmful to plants or insects.
Good against mildew, rust, peach leaf curl, vine leaf blister and so on. I wonder if it works on black spot in roses.

Is this horsetail? Luckily I have some in the pond so I’ll give the tea a go!
Technically, it's Equisetum, which horsetail also is, but it's not the one @Obelixx is meaning. The one which invades any crack in a pavement, or gardens, is the one she's talking about. The pond varieties are slightly different, so may not do the job.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
Just found a few other natural recipes. Apple cider vinegar mixed with water and diluted aspirin are 2 I might try. Surprised to see the baking soda, oil and dish soap coming up time and time again though. Just wondered if anyone has tried it with success as it seems a common recipe?
Vinegar will be bad for the soil's fauna... unfortunately all those "recipes" are nothing more than content by bloggers and silly instagrammers. I would take advice from official sources with professional qualifications especially when a home made concoction can harm the soil. Have a look at professional organic growers or the RHS for solid advice that is evidence based.
So true @amancalledgeorge. Many garden sites are plagued by unsubstantiated ‘advice’ taken from the internet but almost certainly never objectively tested by the posters to see if their words of wisdom are actually bunkum.
Many people swear by Garlic as a natural fungicide as it contains sulphur. It also doubles up as a pest deterrent. Blitz peeled cloves in a food processor or grind with a pestle and mortar then add some water to make into a soupy paste. Leave overnight, strain well through muslin, dilute and spray. Can’t remember the exact recipe but probably loads online. Rather easier to come by than horsetail. The latter is sometimes sold as a readymade concentrate. No idea which is the more effective.

It looks like my raspberry is also affected. Only a few leaves though

What you want is this stuff - https://www.rhs.org.uk/advice/profile?pid=257 which is much more fluffy in appearance.
After looking at the RHS site it seems that growing success fungus stop might be ok
