Randy Kutcher, Chair in Cereal and Flax Crop Pathology, University of Saskatchewan

Randy Kutcher is the Ministry of Agriculture Strategic Research Program (SRP) Chair in Cereal and Flax Crop Pathology at the University of Saskatchewan (U of S). Kutcher completed both his BSc and MSc degrees in Agriculture at the University of Manitoba (UM). His master’s degree focused on blackleg of canola. Kutcher then moved west to complete his PhD at the University of Saskatchewan on barley diseases, followed by a post-doctoral fellowship at Agriculture and Agri-Food Canada, between Regina and Saskatoon, focusing on biological control of weeds using plant pathogens.

Where did you work before U of S?

Before joining the U of S, I worked in private industry for four years at Northern Sales Co. in Winnipeg and then after my PhD, as a Federal Government Research Scientist with Agriculture and Agri-Food Canada for approximately 15 years. I joined the Crop Development Centre (CDC) in the Department of Plant Sciences at the U of S in 2011.

What got you interested in this area of work?

I grew up in rural Manitoba (my grandparents and relatives farmed) surrounded by crops, where agriculture is top of mind. I always liked science, and having that interest, it was logical to get into agriculture.

When I went back to graduate school, I wasn’t sure I wanted to be a plant breeder, but I enjoyed working with fungi, bacteria and viruses (to a degree). I like fungi because you can see them growing in plates and you can trap the spores; they’re really neat organisms to work with. Once I started shopping around for a masters program I got along really well with Roger Rimmer (UM) and I’ve been enthusiastic ever since.

Tell us a bit about what you’re working on at the U of S.

My mandate is cereal and flax pathology, with a cereal focus on Fusarium head blight (FHB) in wheat and barley. Our priority at the CDC is to develop new varieties. In terms of FHB, my crew and I support the breeding program by managing the disease nurseries and evaluating the material in order to provide information to breeders, allowing them to make informed decisions on which lines should go forward. For any disease, relying on one strategy is probably not going to last in the long term so an integrated management plan is needed. The Manitoba Crop Alliance has contributed towards our Canadian Agricultural Partners program where we are looking at the impact of the crop sequences grown prior to wheat or barley on diseases such as FHB and the leaf spotters.

We do a lot of applied plant pathology work in terms of crop rotation, fungicide timing, and use of clean seed; in addition, we look at agronomic aspects of disease mitigation, for example, the impact of seeding date. Recently we have looked optimizing fungicide timing to improve FHB mitigation, and how that fits into an integrated pest management program. Things like trying to decide if and when fungicide will be of benefit, and determining the response to a fungicide application.

Another disease we are looking at (one which I like working on but we have not had severe problems with in the last few years, in Saskatchewan at least) is stripe rust. In 2011 we had a stripe rust epidemic in Saskatchewan. It was the first time a lot of people had seen it so there were a lot of questions about what varieties might be less susceptible and should we spray a fungicide? When should we spray? Is it too late to spray? Should we spray next year? We support the breeding program by looking for new sources of resistance for stripe rust and other management strategies. Unfortunately, because the rusts generally blow in from further south, rotation is not effective so that is why we have looked at fungicide control as another option when resistant varieties are not available.

One other disease we’re working on is bacterial leaf streak in barley. Over the last few years, we’re seeing it pop up across the prairies more and more, with some growers in Manitoba having issues with it last year.

What can you say about the value of farmers providing funding and support to your organization?

Farmer funding is critical. The Ministry of Agriculture provides a set amount of funding for the CDC, but to expand our research endeavors it is critical we have outside funding. Most of the funding for the applied plant pathology work comes from the grower groups to deal with issues on the farm. We’re very grateful for the funding and support we receive from them. We’re doing the best we can to provide the results as fast as we can to help improve farming operations.

How does that farmer funding and support directly benefit farmers?

The benefits to growers might be quickly applied, such as improved manage of diseases from fungicide timing studies (stripe rust epidemic in 2011, and FHB more recently), to delayed benefits, where we’re looking for new sources of resistance that won’t be available to growers for another ten years when the new varieties become available. Therefore, there are a wide variety of benefits that growers can use almost immediately to results that are going to take some time down the road before they see the benefits.

Breeding for genetic resistance to diseases is perhaps a little behind the scenes and longer term, but very important, while sometimes results from integrated disease management research can be given to growers within a year or two of starting the research. After three years of research, we usually have a pretty good idea how to improve management of a disease with fungicides, or possibly even the impacts of crop sequence, as opposed to fundamental knowledge, which usually takes longer to develop. It may take time to diagnose a new or uncommon disease and determine if it is due to a new pathogen or new race of an existing pathogen, or if a previously uncommon disease has become more of an issue due to changes in weather or agronomic practices. We need resources to develop an understanding of the pathogen and the disease, what conditions they need to become a problem, figure out why a disease has suddenly become a problem, and then figure out how to deal with it.

How do you spend your time outside of work?

I have too many hobbies! I really enjoy music, I recently volunteered at the Jazz Festival, and travelling – previously as a student and occasionally through my research collaborations.

What gets you excited about the work you do?

The very nature of the job. Every morning when I come in there is always something to do and it is often very different from the previous day. At the University, I get to work with young, enthusiastic students and I often get phone calls from growers to hear what issues they are facing. These are the kind of things that really make my job interesting. There are some routine aspects to science, but generally there is always something new happening.

What is the best piece of advice you’ve received?

Tenacity. Not everything is going to work out, but if you give it a good try and if you stick with it, things will work out in the end. Really, that is what research is all about, looking at the problems from different angles and talking to many people; there’s always some aspect of plant disease control you can improve to make a difference.

Yvonne Lawley is an Assistant Professor of Agronomy and Cropping Systems in the Department of Plant Science at the University of Manitoba (UM), and has been working with the University for ten years. She obtained her PhD from the University of Maryland in Natural Resource Management specializing in soil science, an MSc from the University of Saskatchewan in plant science, and has an undergraduate degree from the UM in agronomy. Lawley now lives in Winnipeg with her family.

Where did you work before UM?

Before joining the UM, I was a Research Agronomist with North Dakota State University in Carrington, North Dakota for two years.

What got you interested in this area of work?

I grew up in Winnipeg and always had an interest in going to visit my grandparents’ farm near Manitou, Manitoba. My interest in agriculture really grew in high school where I thought, if I can learn how to be an engineer, I can learn about agriculture, and off I stormed into my undergraduate degree. I started off in agronomy and then moved into plant science and that took me over to soil. The more I was learning about plants the more connection I saw between plants and soil management.

Tell us a bit about what you’re working on at UM.

I have had a good relationship with many of the organizations that now make up the Manitoba Crop Alliance and I feel connected to their membership. I have several projects (current and past) that have received funding from MCA. Most of them fall within the general area of crop and soil management. One unique part about the research I’ve done with MCA is that we’ve done both traditional small plot agronomy experiments as well as on farm experiments.

Some of my research has focused on corn and wheat agronomy as well as residue management including vertical and strip tillage. One of my current projects is focused on managing lodging resistance for high yielding wheat, kind of ironic to be working on lodging management in times of drought. I’m also doing a lot of work relating to cover crops. This involves a survey, on-farm experiments, and a crop rotation study at sites across the Prairies where we have some of the crops represented by MCA as part of the rotation. The rotation study is looking at how cover crops influence crop productivity, nutrient cycling, soil health, greenhouse gas emissions, water use, and soil carbon over time. For the extreme moisture project, we’ve been looking at the management of overwintering cover crops like rye to utilize water when it is wet in the spring and then later in the season how the residue from that cover crop could help conserve soil moisture during times of drought.

One thing that excites me about working with the MCA is the Whole Farm initiative. I’m a ‘whole farm thinker’ when I approach my research so I’m excited to see how the Whole Farm initiative grows and evolves. I think this new MCA initiative is going to enable researchers like myself to look not at just commodity specific questions, but whole systems wide projects.

What can you say about the value of farmers providing funding and support to your organization?

It is really enabling to have farmer funding. It’s motivational and it’s essential. Funding from farmer organizations like MCA enables me to pursue important research questions that other funders may not be interested in. It also allows me to train graduate and undergraduate students, which brings value back to farmers. These students are the ones who end up being future agronomists and researchers.

Another thing that’s really enabling is the interaction that comes with having funding from farmer organizations through extension events. They provide a ready venue for researchers like me to connect with farmers, or the graduate students I am training. These events inform me because I get to have conversations with farmers. Those conversations inspire new questions and also help me stay current in the classroom as I can gather feedback, questions and ideas to take back to campus when I’m talking with students.

How does that farmer funding and support directly benefit farmers?

Our aim and hope is that the research questions we’re asking in our projects are relevant to the questions farmers are asking on their farm. I also think there is value to farmers in investing in research that makes its way into the classroom. Having research at universities is important for training, and students get to learn about current research that is happening right now while they’re studying. Whether its at the diploma, undergraduate, or graduate level, new information and ideas go with those students when they graduate.

Government funding is now looking to organizations like MCA to match dollars invested in research and I think this helps gives farmers a voice. These check-off programs are going to be essential for funding agriculture research in the future. As government funding pulls back, that check off is going to be the way farmers have voice in directing funds to the research that matters to them.

How do you spend your time outside of work?

Research and family life have kind of crowded out most of my hobbies over the past ten years, but the ones that have survived are my interests in nature, food, music and travel. My husband and I are both professors at the UM and we have two enthusiastic school age kids that keep us pretty occupied after work!

What inspires you?

The conversations I have with students and farmers are very inspiring. It has been hard to stay excited and inspired in times of COVID, but the conversations I’ve been able to have with students and farmers really keep me grounded and connected. They motivate me to keep moving forward with research under difficult conditions because you can hear the impact and value that new information and ideas bring in these conversations.

What is the best piece of advice you’ve received?

When I was starting out as a new professor, a colleague said to me that you have to trust your gut. If you have an instinct about a project or you observe something that doesn’t seem right, you have to trust it, go after it and pick it apart. Life and research are full of surprises, you have to have confidence in what you’re seeing to be able to ask yourself, why did that happen?

Estimating Yield and Physiological Maturity

Producers and agronomists should be assessing each grain corn field now for yield estimates. Pollination is long since complete and we have an excellent idea of how many kernels have been pollinated.

The following is taken from Dr. R.L. (Bob) Nielsen on estimating corn grain yield prior to harvest. Dr. Nielsen has some excellent articles on corn production that are worth looking into. (www.agry.purdue.edu/ext/corn/news/timeless/YldEstMethod.html)

  1. At each estimation site, measure off a length of a single row equal to 1/1000th acre. For 30-inch (2.5 feet) rows, this equals 17.4 linear feet.
    TIP: For other row spacings, divide 43,560 by the row spacing (in feet) and then divide that result by 1000 (e.g., [43,560 / 2.5] / 1000 = 17.4 ft).

Corn maturity 04

Figure 1. Row length required to measure 1/1000th acre in various row widths – Ontario Grain Farmer (ontariograinfarmer.ca/2017/06/01/cropside-corn-stand-checkup/)

  1. Count and record the number of ears on the plants in the 1/1000th acre of row that you deem to be harvestable.
    TIP: Do not count dropped ears or those on severely lodged plants unless you are confident that the combine header will be able to retrieve them.
  2. For every 5th ear in the sample row, record the number of complete kernel rows per ear and average number of kernels per row. Then multiply each ear’s row number by its number of kernels per row to calculate the total number of kernels for each ear.
    TIPS: Do not sample nubbins or obviously odd ears, unless they fairly represent the sample area. If row number changes from butt to tip (e.g., pinched ears due to stress), estimate an average row number for the ear. Don’t count the extreme butt or tip kernels, but rather begin and end where you perceive there are complete “rings” of kernels around the cob. Do not count aborted kernels. If kernel numbers per row are uneven among the rows of an ear, estimate an average value for kernel number per row.
  3. Calculate the average number of kernels per ear by summing the values for all the sampled ears and dividing by the number of ears.
    EXAMPLE: For five sample ears with 480, 500, 450, 600, and 525 kernels per ear, the average number of kernels per ear would equal:
    (480 + 500 + 450 + 600 + 525) divided by 5 = 511
  4. Estimate the yield for each site by multiplying the ear number (Step 2) by the average number of kernels per ear (Step 4) and then dividing that result by a kernel weight “fudge factor”. Unless your seed company can provide some insight into kernel weight values for their hybrids, I suggest simply performing separate calculations using “fudge factor” kernel weight values equal to 75, 85, and 95. This range of values probably represents that most commonly experienced in the central Corn Belt.

Corn maturity 05

Figure 2. Grain corn yield estimate formula – Iowa State University (crops.extension.iastate.edu/cropnews/2017/08/estimating-corn-yields-using-yield-components)

Example: Let’s say you counted 30 harvestable ears at the first thousandth-acre sampling site. Let’s also assume that the average number of kernels per ear, based on sampling every 5th ear in the sampling row, was 511. Using “fudge factor” values of 75, 85, and 95; the estimated range in yield for that sampled site would (30 x 511) divided by 75 = 204, or divided by 85 = 180, or divided by 95 = 161 bushels per acre.

Repeat the procedure throughout field as many times as you deem representative. Tally and average the results separately for each “fudge factor” used for the calculations.

Remember that this year we have very uneven uniformity in most corn fields, which will influence the accuracy of any yield estimation technique. The less uniform the field, the greater the number of samples that should be taken to estimate yield for the field.

Corn maturity 03

Figure 3: Measurements for each reproductive stage of corn development and how a killing frost would affect yield at that stage.

In early September, we tend to estimate when the corn will reach physiological maturity even more than we estimate yield in each field. In recent years, Manitoba has been getting early to mid-September killing frosts, so the chart above has been a very well-used reference. If you need help determining stage of corn, visit Grain Fill Stages in Corn (Purdue University), or a simple Google search for countless resources on how to properly identify milk line or physiological maturity (black layer).

Economic Benefits to Winter Wheat Even in a Dry Year

By Karli Reimer, Ducks Unlimited Canada

Manitoba’s Interlake region is no stranger to extreme swings in weather. More often than not, the area experiences high moisture levels and flooding, but that hasn’t been the case for the last three or four years. Now deep in drought, East Selkirk farmer, Doug Martin, has been weathering these storms since the mid-80s and remembers all too well the impacts of a dry 1988. But despite the year-to-year uncertainties, Martin has adapted and built an operation that is more resilient to change by implementing practices that better manage his risks. One of the things that helps him do this is growing winter wheat.

Despite the harsh growing conditions all crops faced this season, winter wheat has come out ahead in many areas. On Martin’s farm, his Wildfire winter wheat yielded 60 bu/acre while his spring wheat only hit 45. On top of the increase in yield, Martin cites a few other reasons why the crop is a mainstay in his annual rotation.

“Our winter wheat produced a lot of straw and straw is worth a lot more this year. It produced twice as much as our spring wheat,” Martin says, adding it didn’t take him long to sell the medium square bales that came off his 500-acre winter wheat fields.

Not only did he make money selling the straw, adding to his bottom line, marketing the crop is also easier than it used to be.

“Once harvested, the crop went straight in the bin and then right back out,” he says. “That’s just part of what makes it a good fit on our farm.”

Like many operations, the cost of machinery and labour can add up. Especially when trying to expand a business.

“We’ve expanded the farm the last few years, but I didn’t want to buy another combine and add to our costs,” he says. “I knew I had to spread out the harvest window to use our existing equipment better.”

Having winter wheat in his rotation is key to Martin’s plan of growing crops in harvest windows or in stages. “Growing winter wheat just spreads out our risk and our workload. It’s nice to have it in the ground every year.”

But will it germinate?

The canola is coming off the fields early this summer, and because of this, there has been an increased interest in planting fall-sown cereals. Early to mid-September is the ideal window to get winter wheat in the ground, and crop insurance in Manitoba now allows it to be seeded even later, with full coverage until September 25.

Thankfully, recent rains in some areas have given the parched prairie ground some much-needed reprieve, leading itself to good winter cereal growing conditions, but the crop doesn’t need much moisture to get started after seeding.

“Winter wheat can germinate with only one-third of an inch of rain,” says Ducks Unlimited Canada agronomist, Alex Griffiths. “What I tell producers is to never wait for rain. Get it in the ground as soon as you can and then the next shower will get it started.”

The trick to this, is seeding shallow. “Don’t seed deep,” explains Martin. “It has better germination that way and often small showers are enough to get the crop off and running.”

Winter wheat experts such as Griffiths say .5 to one inch is the maximum depth to seed the crop.

Last fall, some of Martin’s winter wheat didn’t germinate until later in the season, but once it did, it continued to grow and still came through the winter well. Agronomically, winter wheat is a very competitive crop, but he credits new varieties like Wildfire for their excellent winter hardiness package.

IMG 1464

To test or not to test?

Both Martin and Griffiths encourage producers to get soils tested this fall. With the dry conditions, there could be a great deal of residual nitrogen leftover from the previous crop and it’s good to know what’s there and what is needed.

With fertilizer prices on the rise, Martin says split-applying nitrogen, half in the fall and half in the spring, may also be a good strategy. This is just another way to manage risks and to operate more economically.

For anyone new to the crop or for anyone who hasn’t grown it for a while, Martin stresses to manage your stubble properly.

“Watch your stubble as it can break,” he says. “Stubble management is key. Without proper stubble, it reduces the ability to trap snow and to protect the crop over the winter. You may have to slow down on the field especially when desiccating and straight cutting.”

One last practice Martin incorporates to manage costs is controlling weeds after seeding. Because winter wheat is so competitive, producers may not have to spray in-crop for weeds if they are taken care of in the fall.

“This can also save you on inputs if you don’t have to apply a broadleaf next year,” he says. “All these things add up.”

Prairie wheat research groups commit $3.5 million to the University of Manitoba for wheat breeding activities

By Canadian Wheat Research Coalition

August 31, 2021 (Calgary, AB; Saskatoon, SK; Carman, MB; Winnipeg, MB) – The Canadian Wheat Research Coalition (CWRC), alongside the Western Grains Research Foundation (WGRF) and the Saskatchewan Winter Cereals Development Commission (SWCDC), have committed funding to a core breeding agreement with the University of Manitoba (UM). Valued at over $3.5 million over five years, this agreement will ensure the continuation of the successful Fusarium head blight (FHB) nursery program, along with the winter wheat breeding program.

The primary objective for the UM’s FHB screening nursery is to continue evaluating breeding lines for their reaction to Fusarium graminearum – the most common causal agent of FHB. As one of few FHB screening nurseries in Canada, the UM program returns vital information to the network of western Canadian breeding efforts, and is the key to developing future wheat varieties with FHB resistance. While the focus for winter wheat research will be the delivery of field ready cultivars, development of new genetic tools to help improve winter wheat quality will feature heavily. The agreement, which is an increase of $1.6 million over the previous core breeding agreement, also includes the training of students as future scientists in wheat research.

Known for her contributions to FHB research, UM’s long-time winter wheat breeder Dr. Anita Brûlé-Babel is set to retire this December, with Dr. Curt McCartney assuming the role. Prior to joining the UM, McCartney was a research scientist at Agriculture and Agri-Food Canada (AAFC) in Morden, Manitoba, where he focused on cereal genetics targeting resistance to FHB, leaf and stem rust, and orange wheat blossom midge.

“This foundational funding of UM’s wheat breeding program ensures the continued evaluation of FHB resistance of breeding lines from across the Prairies,” says McCartney. “Dr. Brûlé-Babel’s research has been critically important for developing varieties with improved FHB resistance and has provided excellent training for graduate students. With this new agreement, I plan to build upon her successes through the development and implementation of genomics-assisted breeding techniques.”

The CWRC is a collaboration between the Alberta Wheat Commission, Saskatchewan Wheat Development Commission and the Manitoba Crop Alliance with a focus on funding genetic and agronomic wheat research for western Canadian farmers. The UM agreement represents the fourth and final core funding agreement with the public wheat breeding programs in Western Canada. Previously announced agreements include $22.6 million to AAFC, $9.6 million to the University of Saskatchewan’s Crop Development Centre, and $2 million to the University of Alberta. These core agreements provide support to key capacity in the breeding programs. In recognition of the winter wheat and FHB focus of the UM program, WGRF and SWCDC are providing $935,000 and $50,000, respectively, over the term of the agreement.

Quotes

“FHB is a growing concern across the Prairies as it not only compromises yield, but also end-use quality and food safety. As a farmer, my best line of defence starts at variety selection, so having access to FHB resistant wheat varieties is key for my farming operation.”

  • Fred Greig, CWRC Chair

“The University of Manitoba is an important piece of the western Canadian wheat breeding network. Renewing this long-term agreement creates stability for the winter wheat breeding program and ensures access to a coordinated FHB screening nursery that will continue to provide benefits for the wheat breeding programs across western Canada.”

  • Dr. Keith Degenhardt, WGRF Chair

“Winter wheat is a sustainable crop that promotes good environmental stewardship. Breeding for winter wheat varieties that better survive prairie winters is critical to continued uptake and adoption by producers. A better understanding of the genomics which influence winter survival and improve quality will lead to cultivars I can incorporate into crop rotations to enhance my farm’s profitability.”

  • John Burns, SWCDC Chair

“The producer-funded support from the CWRC, WGRF and SWCDC will be critical for supporting a strong program of winter wheat breeding and FHB resistance research at the University of Manitoba. As Dr. Brûlé-Babel capably passes the torch to Dr. McCartney, I know we can look forward to continuing to develop profitable and climate resilient wheat genetics for western Canadian farmers.”

  • Dr. Martin Scanlon, Dean, Faculty of Agricultural and Food Sciences, UM

Where did you work before?

I started working with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) as a summer student in Ridgetown for a couple of years. After I finished my undergrad, I was hired as a Research Assistant with Tracey Baute, Field Crop Entomologist with OMAFRA. That’s when I met Dr. Art Schaafsma, Field Crop Pest Management Professor at Ridgetown Campus. He asked me if I was interested in doing my Masters with him, which I was. The day after my MSc defence I started working for Art as a Research Technician and I’ve been here ever since. I’m now a Research Scientist and I am managing the entomology research at Ridgetown since Dr. Schaafsma retired earlier this year.

What got you interested in this area of work?

It wasn’t until my third year of university that I took my first entomology course. I grew up on a farm and I always knew I wanted to do some kind of research related to agriculture. Entomology really grabbed my interest and it all fit together nicely. The entomology world is endlessly fascinating and always changing. There’s a never-ending number of questions we can study when it comes to pest management.

Tell us a bit about the Mitigation and management of Cry1F resistance in European corn borer in Canada project.

Resistance to Bt corn in European corn borer (ECB) was discovered in Nova Scotia (NS) in 2018. The original Bt corn technology was designed to control ECB and has been highly effective since 1996. Up until 2018 there hadn’t been any field evolved resistance cases of ECB. It’s pretty interesting that it happened in Canada, and NS of all places, especially because of the magnitude of corn being grown in the US Corn Belt and only 35,000 acres of corn grown in NS.

We believe there could be a number of reasons why it may have happened. Originally, Bt hybrids only expressed one Bt protein against ECB. As time went on, more of these Bt proteins were developed and transformed into corn plants by seed companies. So, we have mainly adopted pyramid Bt hybrids in most of the corn growing regions where the plant expresses more than one protein against ECB. Therefore, you have multiple modes of action working against the pests and the chance of resistance happening is much lower. We understand now know that in some of these smaller, shorter season markets, single Bt protein hybrids were still being sold. As a result, there may have been more selection pressure placed on these isolated populations which could be one reason that led to the resistance in NS.

The Mitigation and management of Cry1F resistance in ECB in Canada is the first project we’ve had with Manitoba Crop Alliance (MCA). We really wanted to get Manitoba producers involved with this project because the corn hybrids that are available to the NS market are very similar to those available in the Manitoba market. There are smaller acreages in the province and shorter season hybrids (older genetics) which may still only have the single Bt proteins expressed. This could put Manitoba producers at high risk for resistance.

The project is funded through NSERC and partially financially supported in part by MCA. A new Alliance Program with multiple partners (NSERC matches funding two to one) includes:

  • Grain Farmers of Ontario (GFO)
  • Atlantic Grains Council
  • Manitoba Crop Alliance
  • Ontario Ministry of Agriculture, Food and Rural Affairs
  • Manitoba Agriculture
  • Centre de recherche sur les grains (CÉROM)
  • Perennia Food and Agriculture Inc.
  • Bayer
  • Syngenta
  • Pioneer
  • Ohio State University

All of these partners are also involved in the Canadian Corn Pest Coalition (CCPC) www.cornpest.ca.

Because ECB was controlled so successfully for the last 25 years using Bt corn, it fell off the research radar and we forgot about it as a major pest, which it still can be. Through this project we are stepping back to look at the general biology of ECB in Canada, specifically the situation in NS.

We have a number of questions about ECB, starting with the basics like biology, number of generations per year in Canada and what host crops they are using. We’re studying these resistant populations to determine:

  • Their life history characteristics,
  • Whether the field-evolved resistance is unique compared to resistance developed in the lab,
  • Are they susceptible to the other Bt proteins that are still available?
  • Will there be new Bt proteins we control with down the road?
  • Will alternate host crops other than corn have an impact on how we can control the resistant populations?

Finally, how can we manage the resistance populations is the biggest question because we don’t want the resistance to spread any further or evolve in other areas.

What can you say about the value of farmers providing funding and support to your organization/work?

I think it’s really important that farmers are involved in funding and supporting research. We’re really fortunate in Canada that this model is strong and we have good, strong relationships with farmers. Farmers can direct research they feel is important and direct the research priorities to make their operations more sustainable.

How does that farmer funding and support directly benefit farmers?

The goal of the research is to make the results practical and something producers can utilize. We can incorporate some of the basic research and underlying science to produce an applicable tool or practice for the growers at the end.

How do you spend your time outside of work?

Farming outside of my job keeps me busy. I also enjoy golfing, gardening, going to the beach and doing crafty things like stained glass.

How do you celebrate agriculture?

I grew up in a family of farmers on both sides so agriculture has always been a part of my life. It’s been one of the most rewarding fields to work in even though its very hard work. To me, celebrating agriculture is appreciating that and understanding how important it is in everyone’s lives.

What is the best piece of advice you’ve received?

My dad has always said, ‘It’s a poor day if you don’t learn something’. I think I got a lot of my love for science from him. He’s a farmer whose always been super curious and interested in biology and science.
