Robert Kremer is a microbiologist with the US Department of Agriculture’s Agricultural Research Service and an adjunct professor in the Division of Plant Sciences at the University of Missouri. He is co-author of one of five papers published in the October 2009 issue of The European Journal of Agronomy that found negative impacts of Roundup herbicide, which is used extensively with Roundup Ready genetically modified crops. Kremer has been studying the impacts of glyphosate, the primary ingredient in Monsanto’s Roundup herbicide, since 1997.

The Organic & Non-GMO Report interviewed Mr. Kremer about his research and the reluctance of the USDA to publicize the findings of the five papers.
