6084 Mike here in Winters, California. These photos were taken on a Salvia Clevlandii leaf, date and time as noted on photos. They were taken with an Aven eScope, so I don’t know the magnification, but these were not visible to the naked eye. Any help greatly appreciated as this has turned into an infestation of over a dozen previously healthy plants. Thank you.
These appear to be scale insects of some kind; try applications of an insecticidal soap for control. Ed Saugstad, retired entomologist; Sinks Grove, WV.
