Andy i watched Beech grove on tv this morning he said scab was soil too wet ,we lost 50/60% of all our crop this year with the same scab but it was, believe it or not twice as bad as yours and we had to throw them
We did have some torrential downpours this summer.
Maybe because the affected potatos were grown under plastic with just a slit for the leaves to pop out caused them to scab and, rot (large amount) because there was too much humidity under the sheet and not enough air could circulate?
All my others without plastic were perfect!
