Isn't that a good thing?  Neonicotinoids DO have the beneficial property of
low mammalian toxicity.  But they have some really bad properties as well
(such as very long soil half life).  One of your earlier posts indicated
that sulfoxaflor does not have a long residual life.  Is also has more
reversible binding.  So isn't that good if we enact laws to ban a
problematic class and invent others with similar modes of action but
improvements?
