Aphanomyces Episode 1: The scope and impact in North Dakota and Montana

In the pulse growing regions of Montana and North Dakota, Aphanomyces root rot has caused a crisis in a crop that is vital to farmers and the region at large. In this first video Sean Haney from Real Agriculture visits with Blake Rasmussen, a farmer in Plentywood, Montana, and Jeanie Rude, Agronomist at Pro Co-op Ag Center, to shed light on the historical context of this problem and the widespread impact this disease has on it has not only on Blake’s farm but the community, as well..

This video is a collaborative effort between Real Agriculture, the Pulse Crop Working Group, North Dakota State University, and Montana State University, with funding provided by USDA NIFA-CPPM through the North Central IPM Center.

Aphanomyces in North Dakota and Montana Episode 2: Where do we go from here?

In Montana and North Dakota, Aphanomyces root rot is wreaking havoc in pulse crops that provide immense value to farmers and the region at large. Join us in this second video as we hear from Blake Rasmussen, a Sheridan County farmer, and Jeannie Rude from the Pro Co-op Ag Center, shedding light on the extent of the damage and its implications for pulse crop production in the region. They also discuss how collaboration between farmers, campuses, and extension services can help identify and combat the disease while promoting best agronomic practices to ensure the sustainability of pulse crops in the rotation.

Observations from the road: Lentils

This week the Extension Plant Pathology Lab at Montana State did a tour of lentil production areas of Montana. We observed some agronomic and insect issues while searching for root rot.

Presented by Mary Burrows, from the Schutter Diagnostic Lab.

Wheat streak mosaic virus tools and management for fall planning

This week we discuss cereal viruses, their management in spring 2020 in Montana, and a tool called AWaRe (Assessment of Wheat streak mosaic Risk) to help growers think about risk factors this fall.

Presented by Mary Burrows, from the Schutter Diagnostic Lab.
