Anner.... this is a very intriguing idea!  A new line of attack.... the egg
itself.  I can tell you that one of our NY hybridizers, Dana Borglum, burns
off his irises each year.  This is NOT effective on borer (although he
thought it was till Carol Warner nailed him at a conference).

But I AM very interested in your dormant oil thoughts...   we DO have a large
borer problem here (large problem AND large borer).  But I don't want to take
the chance and be the experimenter... UNLESS I were to try it in one bed I
don't particularly care about.  The other front of attack, of course, is the
moth.  Love to hear of someone who finds an irisborer moth predator or

Kathyguest... who hopes she can remember this vow all the way to November!
