Summary. Tyrone Hayes is a researcher at the University of California-Berkeley who claims his research shows that the herbicide atrazine harms frogs.

Faulty Science

• Hayes has a history of:
  • Sub-standard procedures. Not following Good Laboratory Practices;
  • Secret methods. Not sharing his methods with other scientists; and
  • Secret data. Refusing to provide his original data to the U.S. Environmental Protection Agency.

Agenda. As an anti-atrazine activist, Hayes:

• Recruits members to his anti-antrazine AtrazineLovers’ Network;
• Encourages people to complain about [[atrazine]] to the EPA, Congress and Syngenta;
• Has received funding from anti-pesticide activist groups like the World Wildlife Fund and the W. Alton Jones Foundation;
• Is promoted by the anti-pesticide Natural Resources Defense Council;
• Has received awards from anti-pesticide groups like Beyond Pesticides and the Pesticide Action Network (UK); and
• Works with Environmental Media Services.

Hayes is also the subject of an filed by atrazine manufacturer Syngenta concerning taunting and obscene e-mails sent by Hayes to Syngenta.
