In western Pennsylvania there are still bottled water suppliers that will
handle dry ice, and sell it to sober looking adults. I've heard success
stories of using CO2 saturation in a confined area to get rid of mites
before. If the plant is small enough, you might consider confining it in a
relatively air-tight box. If it is not, and you are considering treating
the entire greenhouse as it looks like has been suggested, then there are a
few otehr considerations to account for.
First the levels of CO2 which will kill off the nasty evil bugs will also
snuff out a human life rather quickly. I recall a few years back there
were several lives lost on a mushroom farm when worked went into
propagation tanks that had not been properly vented. I forget wether it
was carbon dioxide or methane that killed them, but the result would be the
same, severe oxygen deprivation.
Of course some plants suffer CO2 burn, or damage from high CO2 levels.
I've not heard of this happening from short term mite treatment, only from
long term CO2 supplementation (to speed growth), but then I've not heard
too many stories about CO2 and mites either.
If you succeed (or if you fail and are willing to tell us about it) I would
love to hear about it.
