I have just dug up my onions and shallots and about 30% of the onions have it (all the white ones, some of the brown/normal onions and only a couple of red ones). The shallots had none!!! I am forgetting onions sets in future and will carry on growing the shallots.

My onions are dying down as if they have got it but when you pull them its keel slugs eating the rooots and a little of the bulb that has then gone rotten but no snotty noses as we call onion white rot here!!

I have white rot in my soil and around 60% of my onions were affected. It was the same last year but more were affected last year. I have dug up my onions this year early, and the ones with white rot on just the roots, I have peeled, chopped the top and bottoms off and sliced them. I then froze them and last year I tried around 10 bags (2 onions per bag) and they were fine to use except in salad. This year I have around 50 bags. The rest I have drying inside the greenhouse on bread trays. They are only slightly smaller than when left to mature so there is a way around it. I check the onions when they get to a reasonable size and when they come out of the ground with little resistance then I bring 'em all in.

i was reading about potatoes and blight somewhere the other day, sorry can't remember where, but it was along the lines of, if some onions (potatoes) don't get it, then let them seed, then sow the seeds from these next year, then keep doing that every year, till they breed a resistance into them ...... presumably if some of the onions aren't getting it, then this would work?

but you only know they've got Rot when you pull them up ... it's in the roots.
