I would like to add an addendum to Dave Green's note regarding pesticide
applications to fruit trees in bloom lest anyone misinterpret the comments
and create problems for him / herself.  First the term pesticide is broadly
defined and includes everything from rodenticides, herbicides, and
fungicides to insecticides.  Second some pesticide applications can be made
legally during bloom.  These include the application of fungicides for
disease control as Dave indicated, but also streptomycin for the control of
fireblight.  Growers may also apply some growth regulators or foliar
nutrients. These materials do not cause bee kills.  Therefore, simply
observing a grower making a spray application during bloom does not mean he
or she is doing anything wrong or illegal.  Even a bee insecticide kill and
the observation of a bloom application by a fruit grower does not mean the
two are connected, since the insecticide could come from another source
(we've had such a case in Virginia).  Most growers and extension agents are
well informed as to the importance of bees for pollination and know the
dangers of applying insecticides to any plants in bloom, including ground
cover plants.  Occasional misuse does occur, but it is the exception rather
than the rule.  Spray recommendation bulletins are updated yearly in most
states, so no agent or grower should be following old information.  It is
good to be concerned, but also be sure of the situation before accusing
someone, or creating ill feelings because of a false accusation.  If you are
concerned about possible problems, talk to the grower.  Most of those with
whom I've worked in the past 15-20 years are interested in doing what they
can to protect bees and many are good supporters of the bee industry.
