Nitrogen is not totally inert, reacts with some metals that can be used as
pigments.. Fungi acceleration is after opening the chamber, not in the
chamber. More researchs needs to be done in this area, hopefully it will be.

Dear pestlist friends,
From our experience, when it comes to funghi anoxia doesn't interfere with
them (at least at a point that could be considered a treatment). For this
kind of problems mixing insects and funghi, we use anoxia and for selected
critical items with fungus we find freezing and

I want to put in a word for thermal treatments.
Argon is a by product of collecting nitrogen, no extra cost involved. Yes,
nitrogen is used most often based on cost and easier to contain in a
chamber. Nitrogen does not penetrate as well as argon, look at your periodic
table for weights. Use your FTIR to test argon verses nitrogen on real

Friends -
I recall many years ago, when ethylene oxide was in vogue, the Italians
reported fumigated articles were more prone to fungal development after
fumigation than before. Perhaps someone is confusing the nitrogen/argon thing
with the old reports generated when ethylene oxide was the
I know of one italian study by Flavia Pinzari that investigated the effect of
low oxgen environmentes (they used nitrogen, I do not believe that argon was
tested at all) on fungi. There was indeed one Aspergillus species that produced
more spores after the anoxia treatment than its untreated
