I wouldn't be too keen to add onion white rot to my heap - even though I
can get it up to quite a high temperature most years. Anything else I
consider fair game though I will burn blighted plants if I happen to
have a fire I have never been sure that the smoke isn't capable of
spreading the infective agent as spores.

White rot is very different but, in most gardens, the soil either has
it or does not - in mine it does, so the allium vegetables are a
waste of time. Chives and decorative ones seem OK.

The smoke can certainly spread spores, but I don't know which will
survive it.
