Hi All

Here I am sitting on the fence between the OBA who want a total ban  
on neonics and many on this list who say that neonics are no  
problem.  The 1000s of documented colonies lost in Ontario and  
elsewhere due to corn planter dust occurred because pneumatic  
planters were used.  The Scott Dupuis study, which Randy was invited  
to witness, was carried out on canola where conventional seed drills  
are used.  The statement above therefore becomes true only if one  
word is removed.  It is        reasonable, therefore, to conclude  
that crop-applied pesticides in general, or neonicotinoids in  
particular, are a major risk factor for honeybee colonies, given the  
current approved uses and beekeeping practices.
