Hi all,
I have grown Cara maincrop potatoes in my allotment for several years now, and the variety produces very good yields.  However, over the last few years I am finding that many of the tubers suffer from spraing.  Without knowing precisely which virus is causing this, the fact that I see very little powdery scab leads me to think that Tobacco Rattle Virus is the culprit, which I know is spread by free living nematodes.
These are practically impossible to eradicate, so I am looking to change my maincrop variety.
Can anyone suggest something similar to Cara please ?
Thanks, David

I threw a whole bag of Cara out last week, hadn't ever heard of spraing, thought it was blight😂😂.  I wonder was it in the seed?  I had already ordered Cara so will try them again but I am also trying Setanta and Maris Piper to see how they go.

Have you noticed the TRV virus on the leaves of the growing plants to confirm the diagnosis?
