Hi all:
        I was wondering if anyone knows whether I can be as bold as the
manufacturer suggests when the growers I pollinate for are using carbaryl in
the new sevin xlr plus formulation.  (They say they must spray these flea
beetles now or lose the crop.)  The label says that "precautionary measures
(they are speaking of beehives) may be discontinued after spray residues
have dried."
I phoned the canadian agricultural research branch of the chemical's
manufacturer and he assured me that as soon as the spray has dried I would
have no problems, it would be stuck to the foliage and foraging bees would
not take it back to the hive.  But he also said that the spray was only
toxic to larvae not adults, and so I am having some difficulty believing
him, since the Hive and Honeybee gives LD50 (and an extremely small dose)
for carbaryl and I thought that these were measured on adults.  A prompt
response if anyone knows anything would sure be appreciated because I have
to move bees out or cover them, and I have already been putting bees into
fields that are sprayed, but dried, and I must say with many many misgivings.
Thanks,   Stan
P.s.  I know about pollination contracts and spraying, and I have looked at
the pollinators homepage, etc., but these are the same people I have steady
contracts with and they say they have no choice.
