@TerryDaynard@calestous Half-life of#neonics in soil is ~200 to >1,000 days, so they degrade VERY SLOWLY, and accumulate over time. -
@DaveGoulson@calestous EPA reports lower half-live limits (Xerces review). Long-term accum not supported by 2013 Ont field trials. -

@TerryDaynard@calestous Long-term accumulation of#neonics in soil clearly demonstrated by Bayer's own data, see my 2013 review. -
@DaveGoulson Do you have a link for that? -
@Kate_de All my papers can be downloaded from my#bumblebeelab webpage: http://bit.ly/1sZPrua See Goulson 2013 J Applied Ecology -
@DaveGoulson@Kate_de@TerryDaynard Also see EPA's memo on clothianidin, p20, for half-lives in diff soil conditions: http://www.epa.gov/pesticides/chem_search/cleared_reviews/csr_PC-044309_20-Feb-03_a.pdf … -
@LarissWalker@Kate_de@TerryDaynard Thanks, half-life of clothianidin up to 6931 days = ~20 years! Ouch. - 1 more reply
