Allotments 4 All

I've asked this question on a general thread and I suspect it got lost, so: I have white rot on half a row of onions. I have pulled the affected bulbs; will it inevitably spread to the rest?

It may.. which sounds a pathetic answer, but a lot depends on how fastidious you have been in cleaning shoes tools and hands after examining the onions that have it.

our allotment site has been gradually getting more white rot affected plots, so it seems the spores are either being wind transported or people and animal spread. Or all these ways!

One of the grow your own farms nearby has had 25% of its onions affected. Their response is to move their onions for next year three fields away; a luxury us allotment holders simply don't have.

Bad news I am afraid.
Lift and burn the crop, Dust seed drills with Calomel dust, and do not grow onions there for at least 8 yes Eight years.
Apologies to advise you of this.

I've lost a row of spring onions :(
We don't grow any other onions, why I thought spring onions would be ok escapes me ::)

QuoteCalomel dust,

I'm afraid this is a banned substance now adays  :'(
