Zack Bateson is the Research Manager at the National Ag Genotyping Center based in Fargo, North Dakota. You heard a little bit about the work the National Genotyping Center is doing in episode five with Dr. Brian Jenks.  In this episode we dive deeper into the services they offer to provide DNA testing for farmers and agronomists. Bateson got his start in DNA-based testing working in wildlife biology with prairie chickens and lizards, but says all of the skills can be applied to any organisms including variety detection, herbicide resistance, and soil pathogens, which is where he focuses today. 
“Growers can send us kochia and we can genotype them for the resistance to group 14. Then they're able to have a discussion with either their agronomists or other consultants to see whether it can be another actionable spraying opportunity or if there's something else that they can do about these resistant weeds.” - Zach Bateson
The National Ag Genotyping Center is a private nonprofit diagnostic lab that provides genetic testing to identify pathogens, pests and genetic traits such as resistance to herbicides. This valuable information can help growers determine next steps in treatment of fields without having to rely solely on potentially costly trial and error practices. Alongside these established practices they are also developing identification testing for different causes of root rot.
“The work involved is simpler for a person to do, especially with robotics, we can not only do tens of samples per day, but we can extract from hundreds of samples per day. We can test for multiple genetic markers throughout the day, so we're talking hundreds and almost thousands of data points that can be processed and reported out.” - Zach Bateson

Dr. Brian Jenks is a weed scientist at North Dakota State University based in Minot. He has been in this role since 1997 and over that time he has seen an alarming rise in resistance to many of our herbicides from certain weeds, especially in kochia. In this episode Jenks discusses the resistance problem and some of the work underway to help farmers manage these weeds that are getting tougher every year to control. He also shares an exciting new offering from the Ag Genotyping Center to identify resistance.
“I've been polling farmers this winter and the most common answer I get is about 80%. Farmers think about 80% of their kochia is roundup resistant. So it's a majority of the kochia and we know that there's group 14 resistance out there to Aim and Sharpen. So if we want to control kochia in a burn down, we need to know  if Aim and Sharpen are going to work for us.” - Dr. Brian Jenks
Spray droplet size, travel speed when spraying and the height of the kochia when treated are all factors that greatly affect the success of herbicide use. True resistance however will be able to survive each of these adjustments. Developing new mechanisms of action and products to circumvent the resistance is a lengthy difficult process with no clear immediate solution in site. With resistance observed in many commonly used herbicides, gramoxone seems to be the only one that remains consistently effective. Unfortunately resistance is likely to emerge here too without other measures being taken.
“The worst thing we can do is probably a two year rotation where we're using the same herbicides and the same crops over and over.  I'm optimistic if we can diversify our crops to get a minimum of 3, 4, 5 crops in the rotation,  and then use 5, 6, 7 different modes of action with our herbicides.” - Dr. Brian Jenks

Dr. Chris Graham is an associate professor at South Dakota State University. He’s also the manager of the West River Research Farm near Sturgis, South Dakota. At that facility they focus a lot on regenerative agriculture, including doing a lot of work with peas and other pulses to extend crop rotations in that semi-arid region in the western part of the state. Graham shares about pulse production in South Dakota, focusing mostly on field peas. He also shares some of the complexities of nitrogen fixation, including what it might look like to have farm-specific microbial inoculant mixes in the future. 
“When you look at the growth of wheat, generally the yield is set first and then the protein is made later in its life cycle. And so we often see peas, obviously they're harvested and they start to decay, and that slow decay releases nitrogen  later in the wheat growing season. And so we often see a protein bump with wheat following peas.” - Dr. Chris Graham
While there isn’t a lot of acreage in pulses in South Dakota yet, Graham calls field peas the “nickel slots” of the pulses. In other words, a great place to start incorporating them into a rotation with a low barrier to entry. He highlights that your soil nitrogen content will likely not increase but your input needs may decrease when pulses are used.
“It's still nitrogen that you didn't have to apply and it's also nitrogen that the plant did not necessarily take up from the soil. And so it's conserving some of that nitrogen that's being made available just on that baseline level.  ” - Dr. Chris Graham

Dr. Breanne Tidemann is a research scientist with Agriculture and Agri-Food Canada based in Lacombe, Alberta. As a weed scientist, her job is to explore new and novel ways to manage weeds. Her focus is to research applied management strategies, weed biology and ecology, and screening for herbicide resistance. In this episode, Tidemann discusses the work she has been leading in Canada on the effectiveness of weed seed destruction technology including the use of mills and shares that this approach can be a very helpful tool in the toolbox especially in pulses.
“By and large, on the vast majority of weed species that have been tested in Canada and the United States, we're seeing greater than 95% control of what goes into those mills…There's the odd one here or there that's a little bit lower, but when I say it's a little bit lower, we're typically still talking greater than 80% control.” - Dr. Breanne Tidemann
Tideman shares the concern that at the end of the season the remaining weeds have managed to survive everything the farmer has put them through. They are therefore the fittest weeds that are the most difficult to get rid of. She proposes that rather than spreading those weed seeds all over the field with a combine we need to focus on destroying them. This process may not solve any weed problems for the crop you're harvesting, but it does start the weed management for the next year early and can have real impacts on future production. 
“So there's six main methods of harvest weed seed control. Some of them are things we would consider using in North America, like the weed seed destruction technology.…it's basically trying to turn the combine from a weed seed spreader into a weed seed predator” - Dr. Breanne Tidemann

Farmer and Northern Pulse Growers Association president Sam Arnson and executive director Shannon Berndt join us to talk about their work at NPGA, the importance of bringing the industry together to fund research, marketing and education efforts, and how other pulse growers can get involved. They share what NPGA has accomplished and what the future holds for northern pulse growers in the region.
“This is an exciting time to be part of this industry because we are still a fairly small industry, but we're growing. We're seeing a lot of additional states coming on board with acreage and production that face some of the same challenges that North Dakota and Montana producers face. And so as a collective group of growers, I think it's important that y'all have a voice.” - Shannon Berndt

The Northern Pulse Growers Association is a nonprofit association representing dry pea, lentil, chickpea, lupin and fava bean growers from Montana and North Dakota. Shannon Berndt has been serving as the assocation's executive director since 2007. When not acting as president for NPGA Sam is found farming northwest of Williston, North Dakota.

“People are overall excited next year for pulses to be put into their rotation if their rotation allows it. And I mean by that is their crop rotation and or chemical herbicide usage if it's opened for pulses. I think a lot of acres are gonna go in next year.” - Sam Arnson

In this episode we’re looking at a new pulse crop: sweet white lupins. Dr. Mike Ostlie is the director of the Carrington Research Extension Center at North Dakota State University. In the early 2000s a private company that was developing lupin varieties had gone out of business and the germplasm was given to NDSU to work on varieties. Now they’re close to releasing new varieties and Ostlie joins us to share why this is exciting for growers and for the pulse crops industry in general. 
“It's actually really an exciting time to be in the lupin world right now because there's a lot of interest in it I think all around in people looking for some new food ingredients, for instance, on the buyer side. As well as some farmers that are interested in getting something a little bit different in their crop rotation.” - Dr. Mike Ostlie
While these varieties of sweet white lupins will be new to many US growers, there is also an initiative in Canada to develop and release blue lupins which have a lot of the same qualities. These qualities include being a strong nitrogen fixer, a phosphorous scavenger, and a high protein legume. Ostlie noted that there is some existing production of sweet lupin in Australia that mainly goes to the pet food and livestock feed industries there. 

“The lupins have pretty wide adaptability in the northern plains in the fact that they produce reasonable yield under those very large drought conditions. When they're provided water, the yield potential is quite high….We've seen yields get up to 60 to 70 bushels an acre with lupins, which again, is very competitive with a lot of crops in the area.” - Dr. Mike Ostlie
