Rachel and Gordon Grandison <scicon@xtra.co.nz> I asked Gordon Grandison, formerly nematologist DSIR (now Plant and Food Research), Auckland, New Zealand about nematodes with the proliferating lenticels, and this is his reply:


Re the potato enquiry, I agree with you that the problem is most probably caused by storage in damp bags. It is sometimes called lenticel oedema. This problem is not caused by a nematode.

Root-knot nematode causes a more warty-like swelling and associated with tuber deformation. Lesion nematode causes a darkish scruffy extensive lesion.

Thanks for contacting me. 
All the best for 2019
Best regards
Gordon

Dear Graham,
To be sure, the best way is to remove the potato skin and you will see the Meloidogyne females..if that is the real problem.

Cheers.
