| OK, thanks to all, I have untertaken a repot and have used a weak soln of systemic. My choice: Ortho systemic with acephate. I gave the other plants in the collection a quick shot of it as well, just to try to clean the whole collection. The (second) yellow leaf fell off on its own accord during repot, but I have four good leaves and a number of healthy-looking roots -- not as many as I'd like for a plant of this size (leaves 7" long) but enough to think that if we kick fungus and bugs we should be good through the end of spike and dormancy.
Now: There have been two parallel conversations here, one about rot and one about insects, with no clear answer about which caused the rapid yellowing. The repot was a good thing anyway, since the medium was almost soil-like in its compaction and the roots probably wanted more airflow...
But what about the fungus amongus. Y'all know I've been using physan. And I'm sure the repot/cleaning helped. It was, as always, a delight to have Cynthia weigh in, and to correct the misimpressioin re: crown rot/other rot. (I don't have crown rot.) Don't want to ignore the fungus issue. Should I stick with Physan regimen (misting every day or two) in the places where I think the problem was starting -- e.g. where the leaves meet the stem?
Thanks again to all. You make my (orchid) life worth living.
