Determination of Nonregulated Status: Bayer/Monsanto; MON 87429 Maize Genetically Engineered for Dicamba, Glufosinate, Quizalofop, and 2,4-Dichlorophenoxyacetic Acid (2,4-D) Resistance with Tissue-Specific Glyphosate Resistance Facilitating the Production of Hybrid Maize Seed

Title

Determination of Nonregulated Status: Bayer/Monsanto; MON 87429 Maize Genetically Engineered for Dicamba, Glufosinate, Quizalofop, and 2,4-Dichlorophenoxyacetic Acid (2,4-D) Resistance with Tissue-Specific Glyphosate Resistance Facilitating the Production of Hybrid Maize Seed

We are advising the public of our determination that MON 87429 maize, which was developed using genetic engineering for dicamba, glufosinate, quizalofop, and 2,4- dichlorophenoxyacetic acid resistance with tissue-specific glyphosate resistance facilitating the production of hybrid maize seed, is no longer considered regulated. Our determination is based on our evaluation of information and data Bayer/Monsanto submitted in its petition for a determination of nonregulated status, available scientific data, the plant pest risk assessment, and public comments received in response to a previous notice announcing the availability of the petition for nonregulated status and a draft plant pest risk assessment. This notice announces the availability of our written determination and supporting documents.
