Meet Manitoba Crop Alliance’s 2024-25 high school bursary recipients

MCA_2024-25 HS Bursary Recipients Graphic_X

Manitoba Crop Alliance (MCA) is proud to support agriculture’s next generation. MCA’s bursary program is designed to assist with the financial needs of students pursuing education in a field that will benefit the agriculture sector.

Six graduating high school students from Manitoba have been awarded with bursaries valued at $1,000 each. The six bursary recipients are Rylan Wubbe from La Riviere, Peyton Tolton from Kenton, Caroline Anne McConnell from Cromer, Taylor Unrau from Douglas, Dane Bergen from Carman, and Elizabeth Woodason from Erickson.

“I’d like to congratulate this year’s high school bursary recipients and wish them all the best as they continue their education,” says MCA chair Jonothan Hodson. “MCA is proud to support agriculture’s next generation, and I can’t wait to see these promising, young individuals make their mark on our industry.”

To qualify for these bursaries, applicants did not need to be continuing into an agriculture-specific program. However, they did need to clearly articulate how their continued studies would help them benefit the agriculture industry.

Sunflower Survey 2025

In partnership with National Sunflower Association, every other year Manitoba Crop Alliance and Agriculture and Agri-Food Canada participate in a Sunflower Survey. The collaboration includes several states in the U.S. where sunflowers are grown, so participation in Manitoba is beneficial to the dataset. 

Some of the factors included in the survey are:

  • Field analysis: population, head size, seed fill, yield calculations
  • Weed pressure: weed prevalence
  • Insect Pressure: insect incidence and damage severity
  • Disease Pressure: disease incidence and severity
  • Blackbird Presence: percent blackbird damage estimate
  • Other Limiting Factors: environmental, uneven growth, herbicide damage, plant spacing, and more.

Sunflower diseases make up the bulk of the survey since, agronomically, they are the greatest concern to the crop. The requirements are to assess ten diseases in incidence (number of plants) and severity (% damage to affected plants) of sunflower rust, specifically. 

MCA is funding the participation of AAFC’s oilseed and Pulse Crop Pathologist, Dr. Ahmed Abdelmagid, on this project. Dr. Abdelmagid participates in the field survey and also analyzes stalk disease samples from each field to determine various strains present in Manitoba sunflowers.

This survey is important in a “minor” crop for Manitoba in order to help farmers understand the specific pressures they are working against. Together with AAFC and Manitoba Agriculture, we can use the survey data to create extension for farmers and agronomists that will strengthen the crop’s success on the Prairies. Paired with the U.S. data, we are able to make fair comparisons and and identify Manitoba’s successes and areas that need improvement. This leads to more directed research projects in the future and extension work with farmers on specific topics.

The 2025 Sunflower Survey will begin in late August. MCA is looking for several sunflower fields across the province to include. Please contact Morgan Cott at morgan@mbcropalliance.ca or 204-750-2489 if you or someone you know would like to be contact this summer to be involved in the survey. This tends to be a quick visit to collect data on all points mentioned above and the farmer will be kept informed throughout the short process.

Jitendra Paliwal, Vice President of Research and Innovation, University of Winnipeg

Jitendra Paliwal is vice president of research and innovation at the University of Winnipeg (UWinnipeg) and an adjunct professor at the University of Manitoba (U of M).

Paliwal earned his bachelor’s degree in agricultural engineering in India, followed by a master’s and PhD in biosystems engineering at the U of M. He lives in Winnipeg with his wife. Their two children are following a similar path to their father: one is studying engineering, while the other is studying geology at the U of M.

Where did you work before UWinnipeg?

I arrived at the U of M as a graduate student and never left (until last year). I was there for nearly 30 years, including my time as a student, then a professor in the Department of Biosystems Engineering and eventually associate dean (academic and graduate programs) in the Faculty of Agricultural and Food Sciences. It has been a rewarding journey, and I’ve met many wonderful people along the way.

Tell us a bit about your research over the years.

My research focuses on the storage and quality monitoring of crops grown in Manitoba. I primarily employ optical techniques, using visible and non-visible light to monitor and enhance the quality of various agricultural commodities.

In one project, “Decontaminating stored flax,” which is funded in part by Manitoba Crop Alliance, we are using what is known as advanced oxidative processing. Through this process, we combine UV light, ozone and hydrogen peroxide to zap microbes, so the crop stays free of any kind of microbial growth.

Flax is a high-lipid crop that must remain dry during storage. The goal of our research is twofold: to maintain dryness and, if microbial growth does occur due to elevated moisture levels, to eliminate it effectively. We are exploring non-thermal methods that avoid heating the crop, using environmentally friendly approaches that involve no hazardous chemicals. Our focus is on solutions that are not only effective but also cost-efficient and commercially viable.

In the last year of this research, we are optimizing a combination of UV light, ozone and hydrogen peroxide without overexposing the crop to any of these three. We are looking for that sweet spot where we can decontaminate the crop while preserving its mechanical and functional properties, which are essential in end-product development.

What got you interested in this area of work?

I was always interested in agriculture. Sure, flax was not originally on my radar, but I was always interested in crops, people having healthy food to eat and farmers getting compensated the best they can.

As the population grows, so does the focus on increasing production, but there is less mention of post-harvest management of crops. Crops can spoil in storage, and if we were to stop some of that spoilage, we wouldn’t have to put as much pressure on the production side. This has been one of the main driving forces of my research program (i.e., to contain spoilage and preserve quality).

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

Funding enables progress, but what’s especially humbling about support from farmers is the trust they place in our research to address the challenges they face. Every time they contribute a check-off dollar to a producer group, they invest in the hope that someone will turn that dollar into meaningful, long-term solutions. This kind of funding keeps us grounded; it reminds us to focus on delivering practical outcomes that ultimately support and benefit the farming community.

How does that farmer funding and support directly benefit farmers?

Much of the work we do has a direct impact on farmers, beginning in the lab and ultimately reaching the field. The techniques and tools we develop are only possible because of the support we receive. Farmers have placed their trust in the system, which means a great deal. They keep asking the tough questions and challenge us to push the boundaries of science. That’s how we continue delivering solutions and innovations that tackle real-world challenges on the farm. Thank you for supporting our research.

How do you spend your time outside of work?

I am a bit of a wellness freak, and I like staying active. Tennis keeps my aging body moving, yoga keeps my mind sane and nutritional supplements (like flax!) keep me hopeful, if not youthful. I also dabble a little in cooking, but my kids would argue that my food is more nutritional than tasty.

What gets you most excited about your work?

When you are working in the lab, the “aha” moment clicks when a student or a farmer says, “Well, this helped!” To me, that is a big win. Science is about discovery, but impact is about people. So, bridging the two really excites me.

What is the best piece of advice you have received?

My father telling me to work hard but stay humble.

Humility is one of the most important qualities. You might achieve great success or accumulate wealth, but it’s essential to stay grounded and acknowledge the people who helped you along the way.

Fusarium Head Blight In-Season Article Roundup

Fusarium head blight (FHB), a complex and potentially devastating disease, has been impacting Manitoba farmers’ wheat and barley fields for over 30 years. Although there is no practice to completely control FHB and its impact on grain yield and quality, there are practices that when used in concert can mitigate its severity. Practices should be implemented before, throughout and after the growing season. Practices include crop rotations with a 1–2 year break in between cereals, selecting resistant varieties, fungicide application, harvest management and more.

Manitoba Crop Alliance and the Manitoba Government have numerous articles covering all aspects of FHB management. Below are article links that cover topics specific to in-season risk and management considerations.

FHB Risk Maps

A new Prairie-wide FHB risk map was developed in 2024 for spring, durum and winter wheat, plus barley. The risk map models were developed in Western Canada and are important tools when assessing FHB risk.  The maps provide some insight into fungicide spray decisions, but in field scouting must occur to ensure all aspects of the disease triangle are addressed in the local area.

Fungicide Application and Timing

Fungicides are one prong of FHB management, but one of the few management practices that can be implemented in season. Currently, fungicides can only provide disease suppression. Once you’ve made the decisions to spray, there are a few considerations to think about, including fungicide choice, application timing and spray application technology.

Plant Growth Regulators and Fusarium Head Blight

Do you have questions about how the use of plant growth regulators (PGRs) might impact FHB infection? Research out of the University of Manitoba sheds light on the impact of PGR application on flower retention and FHB infection.

Nandika Bandara, Associate Professor and Tier 2 Canada Research Chair in Food Proteins and Bioproducts, University of Manitoba

Born and raised in Sri Lanka, Nandika Bandara is an associate professor and Tier 2 Canada Research Chair in Food Proteins and Bioproducts in the Department of Food and Human Nutritional Sciences at the University of Manitoba (UM).

He completed his undergraduate degree in agriculture specializing in food science and technology at the University of Peradeniya, Sri Lanka. He then worked in the industry for four years before moving to Canada to do his master’s degree in food science and technology and his PhD at the University of Alberta.

Where did you work before UM?

After completing my PhD, I began a postdoctoral fellowship (PDF) position at the University of Guelph in the Department of Food Science, supported by the Natural Sciences and Engineering Research Council of Canada PDF scholarship. I stayed there five months before I got an assistant professor role at Dalhousie University.

What got you interested in this area of work?

When I was in middle school, there was a 50th anniversary of the Faculty of Agriculture at the University of Peradeniya, the oldest university in my country. A family friend was staying in our home, going to university, and he took me to that celebration exhibition. After seeing all the animals, equipment and different farming systems, I knew agriculture was something I would really like. I selected agriculture as my high school major and went directly to that same university for the agriculture degree program.

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

My research program focuses on improving the protein and bioproduct industries using biopolymers generated in agriculture and food processing. I have three main research themes:

  1. Sustainable technologies for protein processing and functionality improvement: Developing nonthermal processing, fermentation, and dry and wet protein fractionation technologies to produce functional protein ingredients.
  2. Advancing fundamental knowledge related to protein utilization: Using advanced analytical and material characterization techniques to understand protein functionality.
  3. Advancing circular bioeconomy in the alternative protein industry: Use byproducts and waste material from agriculture (oilseed meal, for example) to produce new food ingredients and develop biopolymers for use in sustainable packaging, wood adhesive and other polymer applications.

In a project funded in part by Manitoba Crop Alliance, we are working with sunflower meal from the commercial oil extraction process. One of the biggest challenges with sunflower meal is that it contains chlorogenic acid, which makes the meal green. This chlorogenic acid will co-extract during traditional protein extraction methods. If you bake something with the sunflower protein, it turns green due to a reaction between chlorogenic acid and amino acid.

In this project we developed two new protein extraction methods where we can get rid of those colour compounds and produce an off-white colour sunflower protein. This work focuses on developing protein ingredients and using the remaining material (cellulose and lignin) for value-added applications.

Then we will look at how sunflower protein can compete with other proteins. Right now, the plant protein market is dominated by soy and pea protein to a certain extent. The oil is still the main component, but if we can get a food commodity from the sunflower meal it will increase the value of the crop for farmers.

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

Farmer based funding is huge. This is the second time I have received farmer-based funding for value-added research. To see that farmers are interested in value-added opportunities is encouraging. You can increase primary production to a certain level, but eventually you will hit a ceiling, right? When you cannot go beyond that, you must generate more income from the existing resources you have. That is how you advance the industry, not just by trying to increase yields, but by generating value for the other components.

How does that farmer funding and support directly benefit farmers?

If we can commercialize sunflower protein, farmers will get additional value for sunflowers, not just for the oil. If everything goes well for this project, we will get the sunflower protein as a protein ingredient. That is one revenue stream. If we can break down the lignin and cellulose and produce the other platform chemicals, that can be another revenue source. It is important to increase yields, and it is important to focus on agronomic practices, but at the same time, the future will be based on value-added opportunities.

How do you spend your time outside of work?

I play cricket. We have both competitive and recreational playing opportunities here in Winnipeg.

What gets you most excited about your work?

Working with trainees and seeing them become successful. I have 23 trainees, and they are extremely successful. For example, they have received national and international awards. American Oil Chemists’ Society, which is involved with the sunflower industry, has two major awards for students: the Thomas Smouse Memorial Fellowship and the Honored Student Award. For two consecutive years, one of my trainees won the Thomas Smouse Memorial Fellowship, and in 2025, another student won the Honored Student Award.

The Institute of Food Technologists, an international society, offers the Feeding Tomorrow Fund, a graduate scholarship program, and presents approximately 90-100 scholarships each year globally. Last year, Canadian students received 10, and my trainees got seven of them. For three consecutive years, my trainees have secured the grand prize in the graduate student competition at the Manitoba Materials Conference. I have also had trainees advance to lead international student societies (American Oil Che), which brings me great satisfaction to see them succeed.

What is your favourite food or meal to cook?

Authentic Sri Lankan food! I really enjoy cooking. I invited my entire research group for dinner recently and they really loved the authentic Sri Lankan foods we have.

Introducing Year Two of MCA’s Strategic Plan

Introduction

Manitoba Crop Alliance (MCA) recently developed and released new Step Goals and tweaked Big Goals for year two of its strategic plan. The newly developed Step Goals establish a bright and bold direction for the next year, while the Big Goals tweaks focus and specify MCA’s overarching goals over the next two years. The MCA board of directors and staff worked collaboratively to make these updates. Below is the breakdown of year two of the strategic plan. For a look back on the activities, achievements and challenges from year one of the strategic plan, please click here.

Big Goal Tweaks

There were a few tweaks made to Big Goals, most notably the wording of Big Goal #2. The new wording is more descriptive, emphasizing the intent to build research capacity for the benefit of Manitoba farmers. This change has made the Big Goal more specific and will guide MCA choices towards realizing our strategic vision.

  • Big Goal #2: Strengthen research capacity for the benefit of Manitoba farmers.

New Step Goals

  • Eight new Step Goals were developed spanning all three Big Goals. Many (but not all) of the new Step Goals build on the results of last year’s.
  • The newly developed Step Goal #1 is a continuation of two Step Goals from last year that weren’t completed.

Below is MCA’s strategic plan for 2025-26. Stay tuned for more information regarding MCA’s strategic plan, which will be shared on our website and in our print and digital publications!

MCA Strategic Plan – Year One Wrap Up

It has been one full year since Manitoba Crop Alliance (MCA) released its 2024-27 strategic plan. Over this last year, MCA staff have worked hard to achieve the vision set out by the board of directors and crop committee delegates. Below is a recap of the wins and challenges from MCA’s efforts to execute year one of the strategic plan. If you are interested in what the future of MCA looks like, click here to view year two of our strategic plan.

This three-year plan was developed in 2024 to consciously guide MCA’s future. The plan consists of three Big Goals that will be achieved over the next three years. The plan also consists of nine sub-goals, known as Step Goals. Each Big Goal has three associated Step Goals, which are annual benchmarks and priorities that are to be achieved in a one-year timeframe.

Big Goal #1: Innovate our communications program to increase awareness and engagement with our farmer members.

Step Goal #1: Equip MCA staff to better understand the most effective ways to engage with our farmer members.

  • This Step Goal required staff to redefine how they approach communicating and engaging with farmers to ensure genuine programming impact. Step Goal #1 was completed and built a strong foundation for continued innovation of MCA’s communications program.
  • Major win: MCA staff members completed additional communication training to better understand the most effective way of communicating with our farmer members.

Step Goal #2: Conduct audience research and generate ideas for engagement and awareness that can be implemented through our communications frameworks.

  • Progress on Step Goal #2 has been meaningful but delayed. Due to the breadth of Step Goal #2, robust research is required to guarantee all audience inputs are folded into the development of the new communication framework.

Step Goal #3: Identify strategic communications initiatives informed by training and research that directly address the needs of our farmers members

  • No progress on Step Goal #3 occurred during 2024-25.

Big Goal #2: Discover and fund ground-breaking research.

Step Goal #4: Identify key priorities for investment to build Manitoba research capacity

  • MCA staff identified and met with research partners to understand Manitoba’s agricultural research capacity gaps. These meetings culminated in the identification of key gaps and potential solutions.
  • Major win: three priorities for support were identified and brought forward to the MCA board of directors.

Step Goal #5: Secure north/south partnerships to develop mutually beneficial research collaborations and investment opportunities.

  • Partnerships are key relationships that increase research capacity by leveraging talents and facilities to fulfill knowledge gaps. Corn and sunflowers were identified as the two crops with an absence of research partnerships and were prioritized in this Step Goal. Through in-person and online meetings, strong connections were established with funding organizations and research institutions.
  • Major win: MCA became a voting member of the National Sunflower Association and collaborator with the North Dakota Corn Council. Both partnerships have led to MCA research priorities being fulfilled.

Step Goal #6: Expand Research on the Farm (ROTF) program.

  • Over the last year, MCA’s ROTF program grew in the number of protocols offered and trials conducted. Additionally, a revamped website presentation has made it easier for ROTF trial data to be accessed and used by farmers.
  • Major win: MCA introduced five new protocols for the 2025 growing season, including MCA’s first whole farm protocol.

Big Goal #3: Explore areas for bold investment that unlocks hidden potential and fuels historic progress.

Step Goal #7: Conduct a study to identify value-added opportunities in Manitoba that would open new markets for MCA commodities.

  • MCA encountered several roadblocks in pursuit of Step Goal #7. As a result, this Step Goal was not completed.

Step Goal #8: Increase support to consumer outreach initiatives that educate and inspire the next generation.

  • MCA worked with Agriculture in the Classroom – Manitoba (AITC-M) to build upon their already strong programing to ensure young people gain an early understanding of farming and where their food comes from.
  • Major win: MCA made a historic investment of $195,000 in AITC-M’s classroom garden program. Read the full announcement here.

Step Goal #9: Conduct a “hopes and dreams” assessment with our partners in research and market development to highlight future opportunities for investment.

  • MCA staff reviewed and evaluated proposals from research and market development partners. All participating organizations had a shared vision and commitment to ensuring Manitoba farmers thrive.
  • Major win: MCA identified multiple new opportunities for bold investment to make historic changes for Manitoba farmers.

Rebecca Hallett, Interim Associate Vice President Research, University of Guelph

Follow @RHHallett on X.

Rebecca Hallett is the Interim Associate Vice President Research of the Agri-Food Partnership in the Office of Research at the University of Guelph (U of G). She holds a bachelor’s in biogeography from the University of Toronto, as well as a master’s in pest management and a PhD in entomology from Simon Fraser University (SFU). Following her PhD, she spent two years working as a postdoctoral researcher with Agriculture and Agri-Food Canada in Saskatoon. She lives in Guelph with her husband and has two adult children.

What was your previous role at the U of G?

I’ve been a professor in the School of Environmental Sciences since 1998. Before my current role, I was Associate Dean of Research and Graduate Studies for the Ontario Agricultural College, which includes six departments that focus on food, agriculture, communities and the environment.

What got you interested in entomology?

I must give some credit to my dad. He has always been very devoted and academic about his hobbies. When I was a tween, he began collecting insects. I went into botany because I always loved plants, but the insect connection was there.

When I got to SFU, there were exciting things happening in entomology and fewer opportunities in integrated pest management on the botanical side. I had done some travelling and volunteering in India and thought I might get into international agricultural development work. When I couldn’t use this experience as part of my master’s, I connected with a Canadian entomologist working on a development project in Indonesia. I went to work with him and my move into entomology happened. I knew I wanted to be a scientist from a young age, but I really wanted to do something that was going to solve problems. So, agriculture and entomology were ways for me to do that.

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

My current position oversees the university side of the Ontario Agri-Food Innovation Alliance, a collaboration between the Ontario Ministry of Agriculture, Food and Agribusiness (OMAFA); U of G; and Agricultural Research and Innovation Ontario, whose research stations we operate as part of our research activities.

My training was in chemical ecology using insect pheromones and host plant compounds to manipulate insect behavior for pest management, which has been a theme throughout my work. I work closely with OMAFA, various crop specialists and the provincial entomologists to look at invasive or emerging pest issues that affect Ontario agriculture.

I also collaborate with Jocelyn Smith on the “Mitigation and management of Cry1F resistance in European corn borer in Canada” project, of which Manitoba Crop Alliance is a funding partner. Jocelyn is the scientific lead and we co-advise graduate students.

Two aspects I’ve been most closely involved in are work by master’s students Emily Glasgow and Jenna Straughan. Emily looked at potential links between pheromone races and BT susceptibility, and the heritability and fitness implications of the field-evolved Cry1F resistance trait. Emily graduated a couple of years ago and we’re now co-advising Jenna on related work. Her focus is the phenology of European corn borer and its occurrence in Ontario, number of generations and use of degree-day modelling to predict adult flights. She’s also done work on isotope detection and the relationship between pheromone races and host plant types, testing whether they are as separated on distinct host plants as the literature indicates.

This work is key to understanding the pest’s life history and timing of occurrence, and has implications for integrated resistance management strategies.

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

Support from farmers is extremely important, as they tell us what they need and what challenges they are facing. Today, so much research funding is reliant on leveraging funds provided by industry. I’ve only seen that trend increase through my career as a faculty member. Many of our funding programs are dependent upon showing that what we are doing is important to industry or to the agricultural sector. So, the funding provided by producer organizations is critical to making research – and solutions to the challenges growers are facing – happen.

How does that farmer funding and support directly benefit farmers?

Ideally, through these research projects we can return results to growers. We aim to get that research into practice to help to inform their management practices and decision-making.

Some of the most rewarding things I’ve done have been those that have resulted in changes and improvements for growers in terms of pest management and decision-making. We did one of the first insect-based apps, Aphid Advisor, for example. It considered the natural enemies (mainly lady beetles) that were being seen on soybean plants at the same times as aphids to adjust the decision as to whether an insecticide spray would be needed. In the end, we were able to deliver a service that they could use to improve their decision-making. This is one example of a research idea coming from growers – they saw the lady beetles in their soybean fields and wanted to know what contribution they were making to combatting the soybean aphid.

How do you spend your time outside of work?

My husband and I really enjoy travel. We spend a lot of time talking about where we might go next and what we might do there. We have a little “pandemic trailer” we bought to do some camping and we plan to do the west coast of Newfoundland this summer.

What gets you most excited about your work?

Trying to make a difference. In all the roles I hold as a professor and administrator I try to lead from a place of caring and I want to help solve problems. That motivates me.

Any favourite travel experiences you’d like to share?

I absolutely love Southeast Asia: the people, the food, the climate and the biodiversity is incredible. I learned to scuba dive last year. We went to Raja Ampat in eastern Indonesia, which is one of the most biodiverse marine environments in the world, and it was great. If you’ve been to the Caribbean, there are about 57 species of coral there. Raja Ampat is part of the Coral Triangle and there are over 600 coral species, so all the little ecological niches for all these different organisms to occupy is amazing. We saw such incredible things, from nearly microscopic creatures almost too hard to see to ocean manta rays with 15-foot wingspans floating over top of us. It was just mind blowing.

Managing Bt Resistant European Corn Borer

European corn borer larvae

European corn borer (ECB) has long been a pest of Manitoba corn crops, but it is not only a nuisance to corn – crops like potatoes and hemp are affected as well. The larval stages of the insect are most economically significant due to their tunneling (boring) capabilities which disrupt the flow of nutrients and water, and the integrity of the stalk. Yields can certainly be affected by ECB presence, around 3-5% yield decrease being possible in standard incidences (5-9 bu/acre in a 175 bushel crop) and increasing in more significant infestations.

Until Bt (Bacillus thuringiensis) traits were introduced to corn in Canada and the United States in 1996, corn farmers would rely on cultural practices and insecticidal control when economic thresholds were met. Cultural practices include crop rotation, residue management – destroying stalks where larvae overwinter successfully, and tillage that buries residue deep enough that larvae cannot survive. Insecticidal control is difficult due to timing between egg hatch and the boring phase. Diligent scouting to monitor egg hatch progress is extremely important to time when most eggs have hatched and larvae have not begun entering the stalk tissue yet. Once larvae reach the 3rd instar stage (7-10 days following hatch), they begin to bore into the stalk, and rarely resurface, rendering insecticide applications ineffective.

The introduction of Bt hybrids allowed farmers to not rely so heavily on residue management and insecticide application. Farmers were able to choose a fitting Bt-traited hybrid for their farm and had to match that hybrid with a refuge, or non-Bt, hybrid in 20% (or more) of the field in a block, strip or perimeter method. In more recent years, seed companies have come out with a 5% refuge system, called refuge-in-a-bag, making the system a lot easier for farmers to adhere to.

Unfortunately, non-compliance with pesticide requirements weakens the system and creates an opening for resistance. While the Bt trait is very strong, there is a small portion of the ECB population that are naturally resistant to the trait that controls the rest of the population. If farmers were to plant 100% Bt hybrids, those resistant populations would thrive and reproduce, eventually being the only population remaining.

BT CORN 101 – Manage Resistance Now
HOW RESISTANCE DEVELOPS – Manage Resistance Now
HOW TO MANAGE INSECT RESISTANCE IN YOUR BT CORN – Manage Resistance Now
MANAGING INSECT RESISTANCE VIA REFUGE PLANTING – Manage Resistance Now

Managing resistance on-farm can feel daunting, but it is very straightforward. Best management practices to avoid European corn borer resistance to Bt traits include:

  • Scout for pests and damage
  • Rotate crops and traits
  • Plant a refuge
  • Manage with insecticides
  • Keep accurate records

If there is a suspected case of ECB resistance in a Bt corn field, the following should be monitored to identify the issue:

  • Scout – both Bt and non-Bt corn for damage
  • Field Investigation – verify trait(s) present, evaluate presence and damage caused by ECB, rule out external reasons for damage
  • Contact Seed Company – seed company representative must be informed if ECB damage is found in Bt-traited crop, where it is determined the pest is resistant
  • Best Management Practices
  • Collect Insects – the seed company will likely arrange for live ECB samples to be taken from affected field(s)
  • Resistance Mitigation – if resistance is confirmed, farmer will be notified of next steps (see Managing Resistance in your Bt Corn)

Resources have been developed to help farmers, agronomists and seed companies identify issues in Bt corn fields as resistance incidents have occurred in Canada. Canadian Corn Pest Coalition is a group of industry members that work to develop extension and support to Canadian farmers and industry as insect issues arise. The CCPC has extensive resources available on their website on this specific topic, as well as other insect pests in corn. It is important for members of the corn industry to be educated on pest pressures that could turn into serious resistance incidents. Together we can improve the longevity of Bt traits so farmers can continue to use them safely and effectively.

Act Now ECB Campaign – Canadian Corn Pest Coalition

Contact your provincial Extension Entomologist (John Gavloski, Manitoba Agriculture) or MCA’s Agronomy Extension Specialist – Special Crops (Morgan Cott) for further information on European corn borer resistance, what to do to avoid it, and how to determine if you see possible resistance.

Maria Antonia Henriquez, research scientist, Agriculture and Agri-Food Canada

WEB_Maria-Antonia

Maria Antonia Henriquez is a research scientist in wheat pathology at Agriculture and Agri-Food Canada’s (AAFC) Morden Research and Development Centre (RDC).

Born and raised in Colombia, she completed her bachelor’s degree in agronomy and master’s degree in plant breeding at the National University of Colombia. She moved to Canada and received her PhD in plant pathology at the University of Manitoba (U of M), which was followed by postdoctoral research at the Brandon RDC.

Henriquez is the president-elect of the Canadian Phytopathological Society. She lives in Morden with her husband Oscar Molina, who is also a research scientist at the Morden RDC, leading the Integrated Crop Production Systems Agronomy program.

Where did you work before AAFC?

Before moving to Canada, I worked as a research assistant at the International Center for Tropical Agriculture (CIAT) for five years. CIAT is part of CGIAR, formerly the Consultative Group for International Agricultural Research, a global research partnership that unites international organizations engaged in research about food security.

What got you interested in this area of work?

My father had a big impact on my decision to get into agriculture research. At home, he had a large library with books and encyclopedias covering a wide range of topics, including science, philosophy, medicine and history. When I was nine or 10 years old, he challenged me to find different topics to discuss with him. During my childhood and adolescence, reading those books became my hobby. I spent hours in the library every day, and science and genetics got my attention. I also got inspired to do research with plants. During my bachelor courses and when I did my thesis, I became passionate about plant pathology and plant-microbial interactions at the molecular level. That was my starting point – I will always remember those years.

Tell us a bit about what you’re working on at the Morden RDC.

In my research program, we are using cutting-edge technologies and bioinformatic tools to find innovative and sustainable technologies to enhance genetic resistance and management strategies for Fusarium head blight (FHB) and leaf spot diseases in wheat. I work closely with breeders, plant pathologists, geneticists and agronomists to incorporate disease resistance into Canadian wheat cultivars and conduct applied plant pathology work in terms of crop rotations, development of biopesticides, digital agriculture and disease surveillance.

Many of these projects are funded partially by Manitoba Crop Alliance (MCA). I am leading the project “TEN-TG: A tilling and genome resource for FHB improvement” along with Curtis Pozniak from the Crop Development Centre at the University of Saskatchewan. In this project, we are working with AAC Tenacious, the only FHB-resistant wheat cultivar registered in Canada. We have identified AAC Tenacious mutants that are susceptible to FHB. As we are sequencing the genome of AAC Tenacious, we are going to compare the DNA sequence of those susceptible mutants with the genome of AAC Tenacious to pinpoint the exact mutations resulting in the susceptible phenotype. This comparison will tell us with a reasonable degree of confidence that those genes are in fact involved in resistance. We anticipate this research and the genetic resources we are developing will have an impact in the future with variety development in Canada.

In a digital agriculture project, I am collaborating with Chris Henry from the U of M and Chris Bidinosti from the University of Winnipeg in developing automated systems for detecting and assessing FHB in wheat using machine learning and imaging technologies. By creating both indoor and outdoor automatic systems, the project seeks to expedite the breeding of FHB-resistant wheat cultivars, a model that could be easily adapted to other cereal crops.

I am also leading a project with Steve Robinson where we are evaluating RNA-based fungicides for controlling FHB in field trials. We are currently testing the best combination of RNA-based solutions in yield plots and comparing those biopesticides with traditional fungicides.

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

Funding and support from farmers are essential to fostering innovation, supporting research and development, and leads to the creation of more efficient farming techniques, crop varieties and pest management solutions. This funding is very important. It allows us to explore sustainable agriculture practices that can reduce chemical inputs, enhance soil health and preserve biodiversity. I am grateful for the support from farmers to my research.

How does that farmer funding and support directly benefit farmers?

The funding and support we receive from growers is a step closer to finding solutions to problems that affect the sustainability of the farms. The economic and social impacts extend beyond the individual grower, affecting the entire agricultural sector. By backing different research initiatives, farmers help us ensure their voices are heard and their challenges are addressed.

How do you spend your time outside of work?

Cycling, reading, gardening and listening to music.

What is the best part of your job?

There are so many things, but I would say the opportunity to work towards solutions for problems affecting Canadian agriculture. Particularly, working with important cereal diseases, such as FHB, but the most important is working in collaboration with a diverse group of people from AAFC, government partners, the private sector and universities.

Who or what inspired you?

My father. He is the most intelligent person I have met in my life, and his deep knowledge and understanding across various subjects was exceptional. Endless conversations about the power of the mind, critical thinking and personal values, like integrity, compassion, forgiveness, resilience and strong work ethic, shape who I am as a person. He was always challenging me and telling me to look at things from a different perspective or look for the answer in a different way. That has really stuck with me.
