USDA Unleashes Monsanto's Multi-Herbicide-Resistant Super Maize on Farmers

## Summary

The USDA says Bayer/Monsanto’s MON 87429 maize, a special corn engineered to resist several herbicides and help make hybrid seeds, is no longer regulated starting August 5, 2026. This means farmers and seed producers can grow and sell this corn more easily without extra government rules. It’s a big win for agriculture, helping farmers protect crops and boost seed production without extra costs or delays.

## Abstract

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.

## Effects PRIA read

- MON 87429 Maize Deregulated by USDA: benefit, medium. If you grow, produce, or sell seed for MON 87429 maize (a genetically engineered corn), it is no longer regulated by APHIS under 7 CFR part 340 as of August 5, 2026. That means MON 87429 is no longer subject to APHIS rules governing introduction, including importation, interstate movement, or relea…
