    Let's stay on microbes for convenience. Resistance is a huge
    problem and kicked into gear with the introduction of systemic
    fungicides in the early 70's. Despite warnings from scientists
    aroud the world, EPA yielded to manufacturers (who interestingly,
    argued that EPA did not have the right to regulate a
    mutagen,referring to the fungicide). What I'm looking at is the
    overlap between pharmaceuticals, ag chemicals, and "anti-
    microbials" incorporated into paints, coatings and materials.
    That is, where the same active ingredient is common to all.

    If resistance leads to dominance, what happens when you kick in
    the balance and/or effects on non-target organisms. What are the
    effects of fungicides on bacteria, for example. One fungicde for
    example, causes mutation in bacteria at .5 ppb. So, while we're
    targeting fungi on plants, mold on building materials, or fungal
    infections in humans, what is happening to the bacteria, and the
    natural.sought balnce in microflora/fauna? Going a step further
    and according to a manufacturer's senior toxicologist, the human
    metabolite of their fungicide is now ubiquitous in the environment
    and at a steady state of 5 ppb in the world population. My guess
    is, get a fungal infection and the pathogen is already resistant
    by way of the 5 ppb continuous exposure. Then, treat it with the
    same compound?

    Well, you can see, as we agree, it get's a little more complicated
    than "it ain't mold" group wants to admit. They need a simple,
    neat, clean answer to pull it off. And, as far as I can tell,
    the "it ain't mold" guys aren't even hitting on all the organisms
    they should be concerned with. Throw in the synergistic effects
    of mutiple toxins from multiple organisms, fungi, bacteria, and
    cyanobacteria, and you can easily see why Mr. Connell has a long
    way to go.

    Thanks for your comments, especially on canker. Did it ever occur
    to anyone that fungicidal treatments could fuel the canker
    problem? I think there is benefit in looking at plant pathogens,
    treatments, resistance, etc. Pathogens common to both worlds
    likely respond in the same way when hit with the same chemicals.
