From Allen: >Especially, note the document at > http://www.panna.org/sites/default/files/Memo_Nov2010_Clothianidin.pdf > which is mentioned in the article, though. Is it real? > These days how can anyone know? > > That is the document that we have been discussing in the last posts in this thread. Aaron sent the link to that a few hours ago. I had received it from a friend a few hours earlier. The article has reference numbers for the studies that were sent to the EPA. I have asked now in two posts if EPA lets out the studies that are submitted for pesticide registration. No one has answered yet (Randy said he didn't know), but ***that is how one could know whether it is genuine***. It certainly looks genuine, and if it took wikileaks to get a copy THAT is the scandal. It looks like something that is already in the public domain. But the half life information is shocking to me. The other link in the article leads to Cynthia Scott-Dupree's study on clothianidin on canola and bees of 2007. Stick that in the archives and you will find that we discussed that study on this list a fair bit. So, it is not breaking news. Field trial studies are usually published in a journal. But the soil half life studies are not "research". They just send the samples out to a testing company and extrapolate the half life from what remains after breakdown. Because the testing company was paid they don't release the results, and in Canada unless the chemical company chooses to release them, our pest management regulatory agency will not release them. In this report the results of studies on ten soil types are given. But not the detailed reports (getting those might need a wikileak). But the results at least will promote some discussion on this list I hope. I do wonder how they justify requiring more studies for oil mustard and cotton, and leaving it registered for all the other crops. The deficiencies and concerns are the same. So, don't panic Bob, but when you have a moment you can read the 90 odd page EPA risk assessment of clothianidin because it is good reading.
