I'm sorry to hear your borers are back.  They can be such a bother!  Do 
you find them in your MDBs and SDBs?  I don't know as I've ever found 
evidence of borers in anything smaller than an IB here.  They just don't 
seem interested in the littleuns.

Because I live in such a remote spot (nearest neighbor is over a mile 
away through the woods), and since I have read borer moths are very poor 
flyers, I am hopeful that I will be able to eliminate my borer population 
entirely within another year or so.  I figured I'd apply Merit several 
years in a row to try to make sure I've caught all of them, then quit and 
see what happens.  If I'm very vigilant about inspecting all new irises 
that come in, I *should* be able to prevent reinfection with the nasty 
buggers.

That's the plan, anyway.

Laurie
