Potato scab

[Bren In Pots]

. It's hard work collecting all that leafmold (30 sacks this year) and it really would be easier just to buy my spuds from the supermarket

But they wouldn't taste half as nice

I take it scab should not be a problem for me as all my spuds are in sacks with mpc...also my brassica are growing very well in my raised bed so I will not grow an potatos in there next year as I was maybe thinking of ...great thread so much information about one subject in one place.

I've been talking to some local farmers who grow potato and they say that scab is caused by a soil bacteria called streptomyces.

They deal with this by keeping the soil wet which means irrigating in dry conditions. This promotes the soil microbes that suppress streptomyces and therefore prevent scab.

I also found that the potatoes I grew with mycorrhizal fungi had no sign of scab whereas I had a small amount on the untreated plants.
