Glyphosate, invented and still largely made and sold by Monsanto, is one of the most widely used herbicides in the world. You can read more about it here, along with reporting on Germany's proposed restrictions on glyphosate, and Monsanto's attempt to sue California to keep glyphosate off a state list of probable carcinogens.
NOTE: Monsanto at UC Davis
The University of California, Davis receives millions to fund agricultural research from Monsanto and Bayer. Just recently, US Right to Know donated a huge collection of agrichemical industry documents to the University of California, San Francisco, a pre-eminent research institution and medical center, to be part of their free on-line Industry Documents Library.
These documents shine a light on the public relations, scientific, legislative and regulatory tactics the industry has used to defend their products and profits. “They offer an inside view of the agrichemical industry communications about the health and environmental risks of its products,” said Gary Ruskin, co-director of US Right to Know. “We hope they will prove to be a valuable resource for policymakers, investigative journalists and the public at large.” According to Right To Know, many of the documents known as the “Monsanto Papers” will also be made available which are surfacing in litigation over whether Monsanto’s glyphosate-based herbicide Roundup causes non-Hodgkin lymphoma.
