USDA withdraws corn regulation with event MON 95275

The United States Department of Agriculture (USDA), through APHIS, announced the deregulation of MON 95275 corn, developed by Bayer CropScience for the control of Diabrotica virgifera virgifera. The decision exempts the material from the regulatory framework applied to organisms obtained through genetic engineering.

The agency concluded that there is no phytosanitary risk greater than that of conventional corn. The analysis considered data presented by the company, scientific literature, and public contributions received during a consultation that began in July 2025.

The MON 95275 event incorporates three insect control mechanisms. The material expresses the insecticidal proteins Mpp75Aa1.1, derived fromBrevibacillus laterosporus, and Vpb4Da2, originating from Bacillus thuringiensis. The event also produces DvSnf7.1 interfering RNA, targeting the Snf7 gene of Diabrotica virgifera virgifera. These components work together in a complementary way.

The combination promotes control of root damage by feeding on larvae. The system includes action through protein toxins and gene silencing via RNAi. The main target involves populations with a history of resistance to previous Bt technologies.

Regulatory assessment

Regulatory assessment indicated genetic stability of the event. Sequencing analyses confirmed unique DNA insertion and stable inheritance across generations. Studies also did not identify adverse effects on agronomic traits, metabolism, or stress response.

The APHIS study analyzed impacts on non-target organisms. Tests indicated no relevant effects on pollinators, natural enemies, and soil organisms at expected exposure levels. Results pointed to a negligible risk for beneficial species under field conditions.

The agency also did not identify an increase in invasive potential. Corn maintains a low capacity for persistence outside of cultivation. Dispersal and competition characteristics remain unchanged.

The technical report does not indicate any changes in agricultural practices. Management remains aligned with current systems, including the use of hybrids with multiple events and resistance management strategies.

The MON 95275 event is not expected to reach the market as a standalone product. Bayer anticipates combining it with other traits, including herbicide tolerance and control of aerial pests.
