I will pass on Kathy's message concerning borer and funding sources to
the scientists at Agriculture Canada. My main interest would be to test
the nematodes under different climatic conditions. Our season is short
and the questions arises whether the nematode has time to build up an
effective population and whether there is any chance of it
overwintering. It has to do both to be an economic and effective
alternative to cygon.
As to trapping the moths in summer, the problem is that they are not
keen fliers and so traps, even if they work, are only likely to be
effective over a short range.
On the matter of mulch, I am still wondering why this is necessary. I
do not mulch and my winter climate is far colder than most of the people
on the list. The irises seems to be happy with a lot or a little snow
cover. I suffer more losses from dry conditions in summer than cold in
winter. In nature, most of the irises experience cold or very cold
winter conditions and no one is mulching them. Why, therefore, would
one mulch in the colder regions?
Ian, in Ottawa where we still have not experienced a real frost.
