Phil,
I am still pulling occasional spuds out of store which appear to have ring rot/brown rot?
I appreciate RR is notifiable but wanted to be sure. Having read Rhys' thread of last September, I am now wondering if the problem is Internal Heat Necrosis after all, as posted by Kepouros. This could be logical with the summer we had. I have not suffered from many problems in my long allotment past, and considering the drought conditions, my crop was pretty d**n good.
Having done a good 'google', I may now have been confused by the similar internal appearance of the above mentioned.
