Purdue University’s agriculture and engineering researchers are collaborating with Insignium AgTech to innovate early detection of tar spot disease in corn.
This initiative, backed by the Indiana Corn Marketing Council and Indiana’s Innovation Voucher, leverages advanced DNA technology and hyperspectral imaging to spot disease signs before they become visible.
Kyle Mohler, CEO of Insignium and a Purdue alumnus, emphasizes the creation of a gene in corn that signals infection by changing the color of leaves to purple, allowing early intervention. Meanwhile, Purdue’s C.D. Cruz and his team are experimenting on Insignum’s corn varieties to refine disease detection under controlled conditions.
Jian Jin has introduced LeafSpec, a cutting-edge leaf scanner, to analyze early disease markers in plants. This tool, combined with drone technology, could revolutionize how farmers monitor crop health, offering a rapid response to potential outbreaks.
Tar spot, caused by the Phyllachora maydis fungus, poses significant threats to corn by reducing its ability to photosynthesize, thus lowering yields. Since its detection in the U.S. in 2015, it has rapidly become a major concern due to the lack of resistant corn varieties.
The collaboration aims to equip farmers with the tools to detect and respond to tar spots more effectively, ensuring better crop management and sustainability. Expected to continue through 2024, this partnership highlights the importance of integrating agricultural technology and research to address critical farming challenges.
