My (supposedly fairly blight-resistant) Fantasio Tomatoes have been hit by what looks like the blight.
None of my Crimson Crush are showing any signs of disease so far (cross fingers).
If you don't mind looking at the pictures, and offering advice please. Should I just cut off the horrible looking parts (barring the brown stems) or should I just leave well alone? Or dispose of them? They are not touching the Crimson Crush so I hope there will be no cross-contamination.

If they were mine, I'd cover each blighted plant with a plastic bag (to keep spore dispersal to a minimum) while removing them. 
Fingers crossed the Crimson Crush, will stay healthy.
Unfortunately the weather this year, has been ideal for blight

Thanks Mumsofstig. You mean remove the plants completely or just affected parts?

Once you can see any blight, it will kill the plant in a couple of days - it's very rare that removing leaves works.. The longer you leave the top growth there, the more chance there is of infecting the tubers.

If you remove the tops and leave the tubers below ground for a few weeks, before digging, there's a good chance you will get some tubers to eat

Sorry Mumostig, but are you talking about potatoes now? If so, I was referring to my tomatoes.

OOPS Sorry!
That'll teach me to pay more attention, won't it 

This bit is still relevant though

No problem. The  plants are still there. I've  removed all the contaminated leaves. I will let you know what happens.

Normal advice is to ensure good airflow around plants.
Can’t see from photos but if the crimson crush are in pots I would move them away from the blighted tomatoes and ensure they have lots of space around them too.
If they are in a bed just cross your fingers I’m afraid. As Mum says perfect blight conditions I fear! Good luck HH

Sorry Anton but you need to remove the affected plants completely. They are highly contagious and it will spread to the crimson crush. Also, once you have touched the affected plants do not touch your crimson crush, it will pass blight into them. You need to think of blight as plague for tomatoes , it’s that contagious and rapidly devastating.
Is Bordeaux mix legal in Belgium? It’s been banned here but I know it’s still used in France. If it’s legal I’d do a spray on the not yet affected tomatoes. Good luck!

[Anton]

Thanks for the replies. No the copper mix is banned here in Belgium. I have sprayed all the plants with bicarbonate of soda but that is probably magic thinking. The Fantasio plants are still producing flowers and tiny tomatoess. The Crimsons are not in pots but so far are unaffected apart from some dodgy looking leaves at the very bottom, which I see every year.
