anti-microbial agents & arabidopsis

[Joshua Levin 919 541-8528]

i would like to find out about growing arabidopsis from seed in petri plates
without sterilizing the seeds.  (please do not reply about using bleach or
microwaves.)  does anyone have information on concentrations of fungicides and
antibiotics that are effective against microbes, but do not alter/harm the
growth of our friend arabidopsis?  i will post a summary of responses to the
net.
thank you,
