This episode focuses on a topic that we haven’t talked about too much before: disease management. Specifically, we’re talking about a couple of diseases in corn and in small grains to be aware of, challenges with fungicide resistance, how soil health practices affect disease management, and what it looks like to take an integrated pest management approach to these diseases.
Dr. Andrew Friskop, cereal crop extension plant pathologist at North Dakota State University, joins us to discuss his research in disease management strategies for North Dakota producers. He says he’s always looking at both what the research says and what’s executable on the farm level. To accomplish this he partners with farmers and other regional research extension centers around the state to plant test plots every year.
“There's never a one size fits all approach, but be aware of what you're worried about during the season and put as many tools as you can in place to make it work.” - Dr. Andrew Friskop
Crop rotation and genetic resistance are the initial steps Dr Friskop suggests to mitigate disease risk. Besides Goss’s wilt, he recommends monitoring for evidence of tar spot. Fortunately it is currently not present in North Dakota but could be soon and needs to be scouted for. Ongoing research is working to provide best management practices for targeting this Tar Spot fungal concern. This emerging disease highlights the concern researchers and producers alike have for chemical resistance in regards to disease management.
“When you get a pest out there and you start using the same crop protection product on it for several years or decades, you're going to be able to start selecting for some of those resistant populations.” -Dr. Andrew Friskop
