Re: Nematodes

Rick and Ross and everyone.  Rosalie Figge, who is unable to get the Iris-L
in anything but digest form (won't someone help her??), followed up on the
University of MD study.  See her post to me below.

Ross,

It would also be of interest (I hope) to the Scientific Committee of the
American Iris Society and would probably make a terrific article for the
AIS Bulletin.

If you are an AIS member, the addresses for the above are on page 2 of
the October Bulletin and if you are not I will supply them.

from Rosalie:

 Hi, Kathy - I just read list  823 Where you talked about  nematodes and
mentioned the  U. of Md.  I phoned Joan Roberts - who lives just across the
Mason-Dixon line in Penna. - and used to live down here and specializes in
rebloomers.  I remembered she had had something to do with that research in
that her garden was used by Stan Gill  to collect  borers and try out
nematodes.  She said he had published - she thought - an article on this in
the Bulletin a year or so ago, she wasn't sure - he had sent her a copy of
what he was writing as a couertesy - and that it was too techinical to be
helpful to most people. He had someone with him in her garden and she pointed
out there were no borers among the new seedlings nor  in the display beds nor
in the line-out beds.  However they found them in the older seedling bed that
had been crowded  with weeds, showing that clean gardening was a help.
 toward prevention.
Since he had done the research, and if you wanted to contact him:
