Christy Morrissey presented these results to the Ontario Beekeepers  
AGM in Nov 2013.  One result she expanded on there, that was only  
mentioned in the paper, was a test field that was planted once with  
seed treatment then left fallow(I believe) for four years. The  
chemical degraded only to 80% of original in those four years.  She  
was pointing out that soil types affect degradation rates.
