2025 Field Crops IPM Course Updated and Available for Growers

Apr 07, 2025

By Monica Jean

An online, self-paced course is being offered by the Michigan State University Extension field crops team, providing farmers with an opportunity to earn restricted use pesticide (RUP) credits while reviewing integrated pest management (IPM) for the most common pest problems. In December 2024, Michigan State University specialists provided an update for growers and agribusiness on weeds, insects, disease and nematodes during our Crop and Pest Management Update Meeting. We have now recorded those sessions and made them available, for free, with 4 credits available for Commercial CORE, Private CORE, 1A or 1B.

The recordings have been made available through the Desire-to-Learn (D2L) platform as a course, along with supplemental handouts and videos. This course will run from March to November 2025.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
