Onion rot.

[telboy]

Not neck rot - (basal rot - roots).
Lost 50% of the crop, destroyed all the affected plants. Never had it before.
Interestingly, the affected sets were planted in a well manured site of a gooseberry bush that I dug up last year as the bush had suffered from sawfly & milldew for too long - time to get rid.

Any thoughts folks?

we've had onion rot for several years and tried to avoid growing them,read an interesting post about chopping onions and spreading on affected ground in warm weather it fools the infection to germinate and when there isn't a host plant it dies .I't's supposed to "clean"the ground to some extent but while it sounds reasonable i'm not sure how effective it is ?
