Potato - blisters on tubers

[chris]

Hi folks,

Just emptied a couple sacks of pink fir, and approx half of the tubers have blisters on them. They're potato under the blister, so I'm not sure if it's scab.. could it potentially be a sort of wart virus?

Any reason for them not to be edible, if I cut the blisters off?





TIA!

the pictures aren't working!

How strange, it's loading for me.. Wonder if the host filter by country. I'll download and attach them when I get 5 mins!

Yuk, Chris! Glad you said it was a potato as I might have thought it was something else

[chris]

Right, added them as attachments too.

I find this on most of my soil grown potatoes (not so much on the buckets) and was told in the past by some knowledgable folk on her that is it most likely due to erratic watering. And with our weathe the past few seasons - it makes sense.
Still edible, but they don't store very well.

[chris]

Ah, I did read similar thanks janeyo.. which would have been when we had the hot spell..

I think I'll peel them

Don't think it's anything to do with country Chris, I can see the pics.
'fraid I can't help on the potato blisters though

Can you do a macro shot of the black area Chris,that may be wart developing

Have a read of .......... http://www.fera.defra.gov.uk/plants/...sheets/pwd.pdf

It's not a good look tho.

[chris]

Yup, can do - but probably not until the weekend (am knocking a wall down after work up until the weekend! - so doubt i'll have change to find my slr - everything is in boxes!!)

[chris]

No growths like that on the root system, nor is it just coming from the eyes though! Cool pics mind

[bearded bloke]

Cool,was the black colouring that concerned me,I got the brown scab from erratic watering this year I obviously need a better regime for watering them in tubs

[chris]

I think the black might have been compost, it was late and I only quickly rinsed it I'll have another look when I get chance and take a better photo

Did you ever get to the bottom of this one?

I've just harvested some spuds showing exactly the same features. Only a small number are affected, and it scraps off easily, but would be good to find a reason to stop it in the future.
