Re: OT-BIO-Gene Buhrmester


From: Wjobe@aol.com

Gene,

Welcome to the iris-talk group!  You will enjoy being on it. There is always
lots
of helpful information from the many members.  You don't say where you live,
but
the description of your iris damage also sounds like borers.  They chew on the
edge of the leaves and leave brown streaks too.  They then invade the rhizome
itself and hollow it out.  I say they, but it starts out as 'they' in the
leaves, but
the dominate borer is the one at the end that does the most damage. It , if
I'm
not mistaken, eats the other borers on the way down.  Anyway, by the time the
rhizome is invaded you will only find one borer. Sevin and fungicides won't
even
come close to killing borers. You have to use either Nematodes or Cygon 2.
To find out if it is borers, at the first sign of damage you can open the
leaves and
see if there is any little borers in there.  Tell us where you live and what
zone you
are in. Sometimes that information can be helpful in determining problems.
