Re: Iris Borer and Nematodes


The genus and species for the iris borer moth is --Macronoctua onusta--.
meaning large night flying (Macronoctua)  (onusta -?????????). Used to have
problems with the borer when I lived back in N.J. - but since moving to
Oregon in '87 I have not seen one in any of my plantings.
