Regional Crop Update: August 26, 2025 - September 9, 2025

As we approach the end of the 2025 growing season, several stressors such as the excessive moisture in July and disease pressure have accelerated crop development across the state, particularly in corn. With silage harvest either well underway or wrapping up in many areas, combines are beginning to roll through corn fields. Read on for more details about what ISU Extension and Outreach field agronomists are seeing and hearing from fields across Iowa.

Researchers identify role of genes that boost disease resiliency in rice

Researchers at Iowa State University have identified two genes that can help rice defend itself against diseases, including the devastating fungal blast pathogen. The research team is led by Reuben Peters, Distinguished Professor in the Roy J. Carver Department of Biochemistry, Biophysics and Molecular Biology, and his laboratory advisees, Yiling Feng, PhD student in the Interdepartmental Plant Biology Program, and Tristan Weers, sophomore in biochemistry.

Food security: discovery of a gene for immunity against a disease that ravages rice and wheat crops

The fungus Magnaporthe oryzae ravages rice and wheat crops and poses a formidable threat to human food on a global scale. Researchers from INRAE, CIRAD and the Université de Montpellier, together with the Hunan Hybrid Rice Research Centre (HHRRC) and the International Rice Research Institute (IRRI) have discovered a gene in rice for resistance to this pathogen, challenging the findings of a study that remained the reference for 25 years. Published in Nature Plants on 4 June, these results pave the way to new solutions to improve disease resistance in crops that are compatible with the development of sustainable agriculture.
