Hi Threeb. Good to hear from you!
Isn't
septicide the crime of killing seven people?
I can see it as the name for a
veterinary product, but that's a registered trade mark, and written, not just with an initial capital, but all in capitals in the manufacturer's information sheet. There seem to be some other products using the name too - including one from around a hundred years ago that was claimed to cure many diseases: "Septicide was an impudent fraud made in Milwaukee and sold as a cure for practically everything from 'cancer' to 'chapt hands'..."
However we're looking for words, not brand names. The botanical term
septicidal is in a few dictionaries, and I would probably accept it if it weren't too long.
Wordnik says that
septicide means the same, with the source being the Century Dictionary, which was apparently an absolutely enormous dictionary published around the 1890s-1910s. I find that a bit too obscure.
So thanks for the suggestion, Threeb, but I don't think so.
But I do have to agree with Linda about
digerati - it's definitely not common, and I will change that in due course.
