Thanks, Ed, for your comments on the Bayer Advanced Rose & Flower
Insect Killer, differentiating between it and. other Bayer insecticides on the
market. I was just about to post saying that we had been using the Rose &
Flower Insect spray (which says "also for houseplants" on the label front) for a
month or so now, with little indications of adverse human reaction. We may be
good "mine canaries", as I do have rapid reactions to a number of chemicals,
including many commonly used in the home and in public places, and my
husband has a kidney condition, which means we pick our chemicals carefully. So
far, neither of us has had any problem from the B.A.R.&F.I.K., using it as
Ed describes.
As to Merit, we have been impressed with its effectiveness when applied
at the roots of our hemlocks (for woolly adelgids and scale) and locusts
(for a recurring leafhopper infestation), both of which only needed one
application to eradicate these pests which have not recurred for almost nine
years now. We originally chose the Merit because it could be applied underground
and taken up systemically which seemed to be the best way by far to limit
exposure for us. In the orchid spray, so far it seems to be equally
effective....
One other comment about the original posting on this subject, which came
from an article in the Washington Post: we have had problems with using any of
the oils as a dip. They settle out very fast and we have had orchid damage when
we tried using them as a dip. I suppose if you have a slave ( who undoubtedly
used to wave fronds interminably over potentates' heads)
constantly agitating the mix, you'd be alright--but this slave's
arms couldn't take that method very long! Maybe this will not
happen to your plants, but a word of caution.
