During my search for a biological control for rose crown gall, I found a
company that sells all sorts of strange little buggies, including this one.
As Dan said, this stuff is pretty expensive. For one thing a lot of it has
to be shipped overnight.
Particularly suited to cold northern soils, Scanmask is a large strain of
Steinernema carpocapsae, similar in appearance to S. feltiae, that remains
active down to 50 F. First collected near the arctic circle in Sweden, the
name of this cold-hardy product is a combination of "scan" for Scandinavia,
and "mask" which is Swedish for nematode.
Target Pests: fungus gnats, grubs, black vine weevils, wood borers
(from IPM Laboratories catalog - phone # (315) 497-2063)
When I asked them about the crown gall bacteria, they sent me some very
interesting 'additional information'. Maybe they have articles on how
effective this stuff is also.
