New strawberry deaths again

This topic was considered here in 2010 and 2012. Did anyone find out what the cause was?
I've lost lots of new strawberry plants this year. (2013)
Established plants are OK.
I suffered vine weevil badly about 5 or 6 years ago, losing troughs of strawberries and various small fruit shrubs. Treated them with vine weevil nematode worms. They return every now and then as they have probably become endemic. I lost two crates of productive strawberries last back-end from them.
This die-off is different. The first lot were all from a local outlet, about 6 different varieties. Some I put in pots in the conservatory. Some in hanging baskets, others in troughs and soil beds. I also had plants from various internet suppliers, including Marshall's. Virtually all died as Beryl described.They can't have infected each other, as their source, location and timing have all been different. The odd one has survived, flourished and fruited.
In a trough which had a couple of different old sucker-grown strawberries, I planted one of a dozen Vibrant, and it died while its neighbours didn't.
I think it must be fungal: Black root rot, Verticillium Wilt, as oldherbaceous suggested, or red stele root rot (also known as Lanarkshire disease) although how it has simultaneously got into the stock of suppliers from all over the country is mysterious.
Perhaps research institutions at Rothamsted, Kew, Aberystwyth, John Innes Centre, Norwich, might know what's going on.
