Which Potato Disease

[mpeill]

I'm new to veg gardening, and am growing Charlotte potatoes for the first time. They are tasty, but the potatoes have rather unsightly scabs, and the leaves have white patches. I'll include images of both. Can anyone diagnose the problem and can it be fixed (for this crop and for subsequent years)?

the first one is good old potato scab, and you get it from sandy soils - other stuff as well, but can't remember the rest.
The second one, can't help sorry.

Thanks for that. We do have quite a light soil, and also a bit of a dry spell early on in the plants life, so maybe that was the cause. I had thought the two symptoms (potato and leaf) were one in the same problem, but you're suggesting not. Hmmm.

Yep scab on the first, apparently still eatable, I got it on my Sharpes Express but my leaves were yellowish

Are the white patches very dry, or moist, or powdery?
If they're dry, then I would suggest that it's scorch - from having the sun on them straight after it's rained, the bits that were wet would be burnt worse than the dry bits giving the patchy white appearance. If the white bits are powdery then it may be mildew, although I've never seen potatoes with that before, but that can be caused in other plants by them being too dry, which is also consistent with the scab on the potatoes.
Scab, I think, can also have something to do with the Ph of the soil, might be worth making the soil slightly more acidic for the next crop.

I'm on snady soil and its been a quite dry spring and early summer so theres the scab. I tried to water as much as I could but other than COPIOUS ammounts of water not much you can do. Its only superficial but puts one of jacket potatoes a bit.

I would say it was scab on the potatoes. Could be the soil is too alkaline. You can still eat them - it just means taking the skin off.
The leaves just look scorched - sun shining on wet leaves. I wouldn't worry about the state of the leaves - you're not going to eat them.

Scab is caused by alkaline soil (spuds prefer it slightly acidic, so adding grass clippings may help a bit).

As others have said: it looks very much like scorch on the leaves, caused by strong sunlight on wet leaves
