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.
