Tyrone Hayes, the Berkeley researcher whose atrazine research made him persona non grata at an MPCA meeting a few years ago, will be on Minnesota Public Radio’s Midmorning program (91.1 FM in the Twin Cities) Wednesday, Oct. 10, beginning at 10:06 a.m. The interview should be a good warm-up for the Senate hearing at 1 p.m. that day on pesticides and attempts by government and corporations to intimidate scientists who study the environmental impacts of agrichemicals. A recent article on the Twin Cities Daily Planet website provides nice background on how pesticide research conducted by former MPCA hydrologist Paul Wotzka led to his current role as government whistleblower.
