This is my first post and first full year of ‘no dig’. I have a big infestation of aphids on the three varieties (International Kidney, Charlotte and Mayan Gold) of seed potatoes currently chitting on a windowsill. The Mayan Gold seem worst affected and are getting very shrivelled. I think the aphids may have transferred from some pelargoniums overwintering nearby. My question is: can the aphids introduce disease to this year’s crops?; if so, am I best to ditch these and get new stock now while there’s still time? Many thanks in advance for your advice.
