    Default Potato scab

    Good morning you lovely experts
    Hopefully I have attached some photos, can you wise people tell me if you think it's potato scab or not? Common scan or powdery scab? As I'm not sure in the slightest xx

    Common scab, I think - there's a lot of it on stored potatoes, caused by very dry weather last year.
    It also effects potatoes planted on limey soil, so if you add lime to your brassicas bed, don't plant potatoes there the following year.

    I'm sure it's common scab, it seems to be around on all allotments at least to some degree. As Thelma says, lime / alkaline soil makes it much worse. Also, thin-skinned potato varieties seem to suffer more. I don't worry about it much, it's unsightly but doesn't show once the potatoes are peeled.

    Plant uninfected seed potatoes each year and do crop rotation to minimise the spores in the ground surviving from year to year.

    What do you do if the seed potatoes you bought - from reputable suppliers, mind you - are scabbed? Do you plant anyway or bin them? If I bin them I'll have no main crops of the variety I like. Bah.

    These are my seed potatoes.... That's why I'm concerned. Would you plant these or not?

    They look fine to me, the seed potato rots away anyway. Id have no hesitation about planting those.
