Problems with potato storage - blight?? - pictures

Hi,

I pulled up my potatoes (Nadine - second early) about 5 weeks ago and have them in storage in hesian sacks in my garage.

I have noticed that a few of the tubers are going slightly soft to the touch. I was even concerned that I saw some black spots on a potato that could be blight.

Any thoughts?

Photo not the best but you can see dark spots.

Thanks

the soft ones look like too much dayligh , maybe try paper sacks inside the hessian sacks

Blight on stored potatoes appears as a greyish shadow ,it quickly breaks down in that area first and when pressed your fingers with go into it and it will smell.Checking your potatoes every couple of days mean that you will only loose the affected ones,this is easier in a newspaper lined box and it is easier to check any tubers in contact with the blighted ones.
