My posting AND THE POSTING YOU QUOTED made it quite clear that I was
saying the SAME thing, based on a different source.

You wrote:
It does NOT have resistant spores, but overwinters in living plant
material. Therefore composting blighted potato and tomato haulms
will not transmit it. The statement that such material must be
burnt is an old wife's tale.

HDRA advise:
LIFE CYCLE
Disease suvives the winter in infected potato tubers in the soil or on
compost heaps. The foliage which grows from these develops spores
which spread on the wind.
and
GOOD HYGIENE
Remove potential sources of infection, especially ALL tubers.
Burn, dustbin, or bury at least 2 ft deep.
Same for tomato fruits.

Additionally, I cannot find any reference to Old Wives in the HDRA
statement. Now are you prepared to reveal your original source, and to
say if the author of it would support your conclusions of their work?
