The message
from Martin contains these words:

AFAIR from childhood, the leaves etc. had died back by the time potato
harvesting/spud picking began. Have things changed so much?
Is the acid treatment reserved for crops of new potatoes

Yes, and no.

Harvest your maincrop early and you get a better price, and if the
weather becomes wet, a better yield.

The idea is for the tubers to remain in the ground for a week or two so
the skins harden, which improves their keeping properties.
