I learned of a possible folk treatment for verticillium wilt recently. This is not something I've tried myself, and I've found very little reference material on the subject, so I can't vouch for it in any way. The person I learned it from has a yard with verticillium wilt in abundance. He was told 
to water with diluted urine in the areas with a lot of verticillium
die-back. It seems to help in his case.

Has anyone else heard of this remedy?

My guess is maybe Verticillium or some other systemic fungal infection, or bacteria Agrobacterium tumefacens , which causes crown gall disease. I've seen something similar to what you describe in Hedera colchica in the Madrid
area, only in summer and in watered plants. In those cases, little could be 
done to save them.

My take also Francisco
As you say there is almost nothing is likely to help the dying vine. There 

is the added problem  that once the soil becomes infected with such a
pathogen it is likely to remain a danger for some time lurking in the soil and it would be most unwise to attempt to replant in it. I am wondering if anything can be done to discourage the problem from now spreading through the soil to the healthy neighbouring vines. I have rather lost touch with this field in recent years and perhaps there is some suitable treatment for
the infected ground which I don't now know about. Any information anybody?

One of my wisterias--Japanese, 30 years old--started to shed it's leaves at accelerating speed last week, and now definitely looks moribund. I can't 
understand it.  We've had no extreme heat this summer, and it bloomed
normally last spring. It can't be old age because several other ones growing
near it are nearly twice as old. Does anyone have any ideas about what it 
might be or whether anything can be done?
