===> Borers seem to have at least two hatchings, one in early spring and
their offspring later on.
When life settles just a little, I'll report on the report I have
received on the "Evaluation of Biological and Chemical Applications for
Control of Iris Borer". The results suggest that entomopathogenic
nematodes STEINERNEMA CARPOCAPSAE and HETERORHABDITIS BACTERIOPHORA
produced significant reduction in borers (100% and 87% respectively).
"These insect specific pathogens have many positive aspects for growers
including their ability to kill hosts within 48 hours, ease of
application, safety to humans and wildlife, and exemption from EPA
regulation. Chemical pesticides may offer an advantage in that they are
not susceptible to cool soil (below 10C, 50F) unlike nematodes. Multiple
application of nematodes may improve control in some cases."
The reliability of suppliers seems to vary considerably. I have a list
of about 50 suppliers, wholesale and retail, some with internet access,
in many states & Canada (haven't noticed an Oz source -- are borers down
there?)
Most of the following are popular and well known sources:
