I’ve received some information from John Hoar. In January this year, a three day cross disciplinary summit was held in London to review the state of knowledge on the impact of pesticides on bee health. John has marked up the programme to highlight the key conclusions of each paper. This makes it very easy to read. Skim down and look for bits highlighted in blue or yellow:
– Items highlighted in yellow report finding pesticides (mainly neonics) are bad for pollinators. There are eleven of these.
– Items highlighted in blue report no problem. There are six of these. Four are at least part authored by Syngenta or Bayer researchers. One of the others is about a pyrethroid, not a neonicotinoid. (Pyrethroids are one of the things farmers are falling back on following the partial EU ban on neonics.)
John also drew my attention to bumblebee researcher Prof David Goulson’s blog. This is all interesting to beekeepers and very readable. The latest post concerns just how many chemicals a local farmer sprays on his fields (22 chemicals in all). Makes you wonder how the soil retains any fertility.
