abstract: Genetically Modified Organisms (GMOs) have a polarizing effect in the US. The first commercially viable GMO was Roundup Ready Soy, introduced by Monsanto in 1996, to be used in conjunction with Roundup herbicides. This thesis investigated and delineated the development and deployments of the discourse of Monsanto’s agricultural assemblage of Roundup Ready seeds and Roundup herbicides and its resistant discourses. Monsanto builds its discourse around the safety and necessity of Roundup Ready seeds through federal regulation and toxicology studies. Resistant discourses deployed by Monsanto’s critics problematize Roundup safety and reject Monsanto’s contention that GMOs are necessary for meeting world’s food demands. The discourse analysis pursued in this thesis explored interactions between the dominant discourse and counter discourses and charted their deployments in Colorado’s and Oregon’s 2014 ballot measures that would have required mandatory GMO labeling. Analysis suggested counter discourses were successful in mobilizing people to engage civically. / Dissertation/Thesis / Masters Thesis Communication Studies 2015
