Top winter wheat varieties in Manitoba – 2022

Each year, Manitoba Agricultural Services Corporation (MASC) publishes a Variety Market Share Report based on information provided by Manitoba Farmers. Not only is this information valuable to track trends and patterns, it can also be useful to farmers for marketing and cropping decisions.

In the 2022 edition, Manitoba farmers reported seeding 51,972 acres of winter wheat in the fall of 2021, up by about 15,000 acres from the previous year. Emerson was the most popular variety, seeded on 36 per cent of acres, followed by AAC Wildfire (28 per cent) and AAC Gateway (16 per cent) (Figure 1).

How have winter wheat varieties changed over time?

It is no surprise that winter wheat breeders are continually working to improve the varieties available to farmers, but how do past varieties stack up against new genetics?

With a short height and high yield, CDC Falcon was the long-standing favourite variety in Manitoba. In 2014, it was moved out of the Canada Western Red Winter class and into the Canada Western Special Purpose class.

Registered in 2012, Emerson has been a top variety in Manitoba in recent years, in part due to its Fusarium head blight (FHB) resistance. AAC Wildfire (registered 2015), AAC Gateway (registered 2012) and AAC Goldrush (registered 2016) are also popular varieties. See how they compare to one another in Table 1!

The Manitoba Management Plus Program (MMPP) also has a number of Regional Analysis Tools, including the Variety Yield Data Browser, which allows past variety yield data for many crops to be filtered based on municipality or MASC risk area.

Crop nutrient management research roundup

Manitoba Crop Alliance strives to provide tools and resources to you, our farmer members, so you can make informed decisions to optimize production and minimize nutrient loss on your farm. To do so, we have funded a range of research projects that support farmers in making decisions. Check out the list below for a roundup of our research and extension efforts on the topic of nutrient management!

Optimizing Nitrogen Management Under Conditions of Extreme Moisture

Background: Manitoba farmers are no strangers to conditions of extreme moisture. The objective of this project was to develop data-based decision-support tools to help farmers assess and manage risks associated with fall nitrogen fertilizer management under extreme moisture conditions. The information developed helps indicate when extra measures to protect nitrogen are warranted, based on the risk of nitrogen losses.

Common Preharvest Questions in Flax

What is the staging for a preharvest or desiccation in flax?

Flax is considered physiologically mature when 75% of the bolls (in the field or on a plant) are brown and the boll segments have begun to separate. This is a visual rating that corresponds to a grain moisture content of around 30% and is known as the 75% boll turn or 75% brown boll stage.

What is the difference between a preharvest aid and a desiccant?

Two types of chemicals are available to assist with flax harvest management: pre-harvest herbicides (sometimes called harvest-aids) and desiccants.

  • Pre-harvest herbicides are non-selective systemic herbicides that provide late season perennial weed control and may improve the harvestability of the crop by reducing the amount of green material in the field.
  • Desiccants are non-selective herbicides that rapidly dry down the crop and weeds to allow for an earlier harvest.

Can we use glyphosate as a preharvest aid?

Since it does terminate the crop, preharvest glyphosate may assist with stem dry-down and harvestability, however it is expected that the effects of glyphosate applied alone on flax dry-down can be slow and potentially inconsistent depending on environmental conditions. This all being said, at this time, it is not a recommendation of Manitoba Crop Alliance to apply glyphosate as a preharvest aid due to inconsistent results with maximum residue limit (MRL) testing. If a producer must use glyphosate, it is strongly recommended to speak with their grain buyer to determine if a glyphosate application to their flax will be a marketing concern.

What are the current registered preharvest aids and desiccants for flax in Manitoba?

Head Rot Identification in Sunflowers & Harvest Management

Rhizopus Head Rot

Rhizopus rarely occurs in Manitoba and is more of a southerly disease, however it is possible to see it here after severe storms and hail, followed by very high heat. Identifying factors that separate Rhizopus from other head rots are gray mycelia with very small black structures.

Rhizopus begins as a typical “water-soaked” dark spot on the back of a sunflower head that grows into a larger watery, soft rot and then dries and turns darker brown. Eventually, heads dry down, though this occurs prematurely in comparison to healthy plants, and infected tissue shreds, exposing gray threadlike strands of mycelial growth.

Key points:

  • Enters head via wound caused by hail, most commonly
  • Water-soaked lesion on backs of sunflower head
  • Gray mycelial growth inside the diseased head, which can later present itself on the face of the sunflower head
  • Tiny black spots, about the size of a pinhead
  • 100% yield loss potential due to dropped heads

Sclerotinia Head Rot

Sclerotinia is very common in Manitoba and in several grain crops, which makes crop rotation the best management practice for this prevalent disease. A recommendation for sunflowers is to only include it in rotation when other sclerotinia host crops have not been grown on that field for 4-7 years. Chemical control is used frequently, however due to the small window for application, coverage is difficult to rely on.

Sclerotinia presence can first be found in the field by identifying cup-shaped apothecia growing on the soil surface, which produce ascospores. Symptoms in the field include the typical tan-coloured lesions on the back of sunflower heads that may be soft to the touch. As the infection spreads, the head becomes pliable and easily torn open to reveal black sclerotia bodies amongst white mycelia. Fronts of sunflower heads may have white mycelial growth, or mould, visible between the seeds. Eventually, heads will likely shred and disintegrate leaving frayed vascular elements that appear broom-like.

Key points:

  • Cup-shaped apothecia on the soil
  • Water-soaked lesions on backs of sunflower head
  • Black sclerotia bodies inside sunflower head following disease progression
  • White mycelial growth between and on seeds
  • Shredding sunflower head, resembling a straw broom

HARVEST MANAGEMENT IN DISEASED SUNFLOWERS

Yield loss from sclerotinia head rot in sunflowers is a result of empty seeds, rather than poor quality. In fact, it is not uncommon to find large sclerotia bodies being harvested along with seed and degrading quality in that manner.

Due to the overall degradation of disease plants, not just from sclerotinia, it is a good practice to harvest infected fields first. The diseased areas should dry down more rapidly than healthy plants and standability isn’t reliable, whether that is a result of a stalk rot or head rot. The physical breaking of stalks or dropping of heads leads directly to yield loss due to the inability to pick up the grain with a header.

Matthew Bakker is an assistant professor in the Department of Microbiology at the University of Manitoba (UM). Bakker grew up in Winnipeg and completed his undergraduate degree in environmental studies and biology at Dordt University in Iowa. Working as a lab technician for a company that produces biological control products triggered an interest in research, and he went on to earn a doctorate in plant pathology at the University of Minnesota. Bakker lives outside Winnipeg with his wife and three daughters.

Where did you work before the UM?

I completed my post-PhD training at Colorado State University and then worked as a research scientist at the U.S. Department of Agriculture before I joined the UM just over three years ago.

What got you interested in this area of work?

I’ve been interested in agriculture and its impacts on the environment for a long time. Nothing we do to the world has as big of an impact on it as agriculture does. When I decided to go to graduate school, I wanted to work with a specific supervisor (Dr. Linda Kinkel, University of Minnesota) so I went into plant pathology so she could mentor me. Plant pathology is a fascinating field and a really important one. Disease is a major limitation on agricultural production and there is a lot of wasted effort and wasted production because of it. If we can reduce that disease in one way or another, we can have a real impact on society. It’s a meaningful and fun field to work in.

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

I lead a research group and work one-on-one with five graduate students, as well as various undergraduates that rotate through the lab. The focus of most of our research is Fusarium. We are currently in the second year collecting data for a project called Examining Fusarium growth and interactions with barley trichomes under the hull, which is supported by Manitoba Crop Alliance (MCA), together with SaskBarley. The idea of this research was, looking forward, how do we better manage Fusarium head blight or prevent damage from the mycotoxin that is involved with that disease? I really think plant breeding is the most effective and economical approach. In that case, as a microbiologist, how can I support the breeding programs with new information or new targets for selection?

In talking with the barley breeders at Agriculture and Agri-Food Canada (AAFC) in Brandon, we came up with a question that seemed worth exploring: are there morphological features on barley that make it more or less susceptible to Fusarium colonizing it successfully? There were a few indications in the scientific literature that the trichomes of barley plants provide opportunities for Fusarium, such as by trapping their spores and making it less likely that they wash off the plant. We thought we should look at this characteristic more closely, so that if it does seem significant, the breeding program can try to change that trait in the plant. We are using high-power microscopes to characterize these trichomes in a number of barley lines and are inoculating Fusarium onto these tissues to see whether its growth relates to the trichomes in some way. We are working to determine if this trait is part of the plant that we should aim to manipulate to get better Fusarium resistance.

Another project supported by MCA (together with the Manitoba Pulse & Soybean Growers through the Canadian Agricultural Partnership program) is Achieving full integration of microbiology into assessments of soil health in Manitoba. The idea behind this research is that we want to understand how agricultural management impacts the microbiology of soils, and how might that in turn impact future productivity or disease risk.

This research is an add-on to a larger project run by AAFC where they are doing the field manipulations and measuring impacts on chemical and physical soil properties, but they weren’t addressing the biology. I saw this as an opportunity to add an assessment onto their experiment, to understand what’s happening with the bacteria and fungi in these soils in response to different management practices. This will let us make a more holistic assessment of the impacts of these management practices on soils. We want to get a better understanding of our Manitoba soils and how management practices affect soil biology in addition to the chemistry and physics.

I also teach two courses: Microbes in Our Environment, and Introduction to Biogeochemistry, which is tracing the movement of elements like nitrogen and phosphorus through the environment, looking particularly at how the action of microorganisms changes the chemical form or influences the movement of elements.

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

It’s been really critical to be able to figure out what are the meaningful questions to ask and what is going to have an impact on society. Having support from the farmers has really helped with that. I’d like to express my gratitude to farmers for entrusting me with some of their research dollars and to say that I am always open to hearing from them about what their priorities are in terms of research needs.

How does that farmer funding and support directly benefit farmers?

We are using those funds to ask questions that are intended to meet farmers’ needs. I’d like to repeat that I am always open to hear from people what their priorities are in terms of research needs, especially in relation to my expertise, diseases of cereal crops and soil microbiology. Our research is really intended to serve farmers. Ultimately, our research should result in farmers experiencing fewer losses to disease.

This funding also provides the resources for me to support additional students training as microbiologists that I wouldn’t be able to otherwise. Having these highly qualified trainees who understand plant diseases and how to do research is going to serve the agricultural community over time.

How do you spend your time outside of work?

My family keeps me busy! We are currently working at some home renovations.

What gets you most excited about your work?

The chance to understand better and learn something new about the living world, which I think is endlessly fascinating. Having lived in various other places and done research, the agricultural scene in Manitoba is really fun. I love the diversity of cropping systems that we have here, and I hope it continues to be a feature of our agricultural system in the future.

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

The idea that most of what is required to do good research is persistence, which isn’t complicated: you just have to keep on going.

Shaun Sharpe is a research scientist with Agriculture and Agri-Food Canada (AAFC) at the Saskatoon Research and Development Centre (Saskatoon RDC). Sharpe grew up in Nova Scotia and completed his bachelor’s degree at Mount Allison University and his master’s at Dalhousie University. He then moved to Florida, where he completed his PhD research on strawberries and his post-doctoral research on tomatoes, peppers and occasionally cucumbers at the University of Florida. He and his wife now live in Saskatoon with their dog and cat.

What is the best part of your job?

I think the best part of my job is getting to work with plants every day. They are such a big part of my life that I’m very thankful to be able to have this as my job, and as one of my passions outside of work. I’m very grateful this is the path I was able to go down.

What got you interested in this area of work?

I wanted to be a veterinarian (my wife is one now) but after a very tough first day in the clinic, I changed my mind quickly. I met a professor at Mount Allison who brought out my interest and passion for plants. He worked in forestry primarily, and had me teaching three different courses for him. I did my project with him and he is the one who sort of gave me the direction to go for my master’s and PhD, and where to go from there. When I was getting ready to do my PhD, Nathan Boyd moved to Florida and was looking for students. That’s where my interest in weeds and their underlying ecology came from, learning in his program and learning how to do research from him.

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

The top priority for my research program is to prevent and mitigate risk associated with herbicide resistance. For resistance, the major complication is a result of the long-term use of herbicides. The result is too much accumulated death of plants, which is a consequence of how we are choosing to control those weed populations (spraying herbicides). We want to attack this underlying issue and look at what we can do to reduce the amount of death without necessarily removing the option of herbicides, but to take the pressure off of them. Over time, the populations are building, so the end goal of my program is to pull infestations downward by helping to provide farmers with alternative options.

The idea behind the Stimulating germination of wild oat and volunteer cereals from the soil seed bankproject was to provide farmers with a control strategy to use in the fall, post-harvest, to rely on frost to kill seedlings, or pre-seed as part of a stale seedbed strategy with an herbicide. Wild oats tend to flush after the crop has emerged and I think part of the issue is that we’re not getting good control later in the season (there is more coming up after the spray window is gone). Those wild oat populations emerge and replenish themselves, keeping that pressure on our herbicides. Ultimately, we are hoping that we can reduce our baseline infestation that will help with prolonging herbicides and the amounts of plants emerging later.

The project with the pyroligneous acid (wood vinegar) was a one-year project of greenhouse work testing a few applications and trying to develop a use pattern we could use in the field. The question was, can we reduce infestation by applying a product that stimulates the seeds out when we want? If we could stimulate them to come out, especially wild oats (which have a very complex dormancy), we could use additional methods of control. While there has been some work with fertilizers, pyroligneous acid hasn’t been used in the field as much. We completed 24 different experiments and developed a use pattern for field applications and identified some concentrations of pyroligneous acid. This research should be published later this year.

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

It’s absolutely critical. AAFC is part of the public service, there to help Canadian farmers with the issues they face on their farms. It’s feedback from the farmers that helps us understand what the major issues are that they are facing on their farm. A lot of times that is through the commodity organizations or through agronomy extension. Their support means everything.

How does that farmer funding and support directly benefit farmers?

It directly benefits farmers because firstly, it helps to train new individuals on the Prairies about herbicide resistance issues. For example, students through my program and those hired through the Federal Student Work Experience Program (FSWEP). As well, it helps researchers better understand the issues farmers are facing and learn where they are severe. With research, it’s never just identifying a problem and saying, “Here is the end of the road and here is the answer.” It’s usually asking more questions, like, “What is the resistance and how is it impacting different facets in different environments?” Farmer support helps me understand these issues more closely and build information to apply to other areas that have the same issue. Resistance is an issue that faces everybody.

How do you spend your time outside of work?

We have a couple of rescue horses my wife and I enjoy spending time with – it’s great to be able to go out and visit them. I also really enjoy gaming when I have the time.

What gets you most excited about your work?

I think it’s better understanding a problem we don’t really know the answer to. Doing experiments as a way to better understand issues that are very ongoing for our environments really excites me.

What are you excited about for the future of agriculture?

I’m very excited about the development of technology. I think it’s a very booming area and there’s going to be a lot, possibly even an information overload for some. There is a lot of promise and a lot of potential tools to hopefully make life easier for folks. Not necessarily to replace anybody, but to give people tools to make their lives much easier.
