>> Organosiloxane surfactants, the most novel class of non-ionic
surfactants in agrochemical formulations, have been widely used around
hives or in honey bee foraging areas as pesticide spray adjuvants.

hive samples and environmental matrices.
Now, this will be most interesting, and may reveal more ingredients of
the chemical soup in our hives. I wonder what kind of interactions are
possible?
We have been speculating about the question of so-called inert
ingredients for years. It has been reported here, for example, that two
different brands of a fungicide had differing toxicities to bees. We
have wondered who decides than an ingredient is indeed inert --
especially if it is an important part of the formulation and contributes
to efficacy. While water is a carrier, the other components obviously
-- to me at least -- are active in some fashion and should be considered
alone and in combination.
While a perceived overly-accepting approach to new pesticides by the
regulators and approval of new products on the basis of non-public
research selectively supplied by applicants has been widely criticized,
the apparent free pass given to so-called inert ingredients may be the
real worry.
