Bacterial Blight Reported In Manitoba Oats

Jun 26, 2018

Bacterial blight has been reported in many oat fields in south-central and south-eastern Manitoba.

"Oats are a little more susceptible to it than your other cereal crops, although it can occur across all of them," said Manitoba Agriculture Plant Pathologist Holly Derksen. "Typically it's just in the lower canopy. It likes a little bit of moisture and cooler temperatures. It can spread pretty easily in the field, especially if there's traffic."

Derksen notes typically the plants grow out of bacterial blight and it is not normally a yield limiting issue. It can't be controlled with a fungicide since it is a bacterial disease.

She adds environmental stress symptoms, such as leaf tip scorching, have also been reported in oats.

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.
