Faulty Science

- 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
