Most seeded winter wheat varieties in Manitoba – 2023

Preventing and Monitoring for Insects in Stored Grain

By John Gavloski, Extension Entomologist at Manitoba Agriculture

Grain beetles can be an issue in high infestation years, so it is important to review management strategies. The first step is knowing what species of beetle is present and whether it is a species that feeds on the grain itself, or more on fungus growing on the grain or in the bin. Without magnification, it can be difficult to determine the difference between rusty grain beetles, one of the more common beetles feeding directly on many stored grains, and foreign grain beetle, which is primarily a fungus feeder.

Note the club-shaped antennae on the foreign grain beetle in the photo. If placed in a glass jar, foreign grain beetles will climb up the sides, while rusty grain beetles cannot.

Preventing insects being introduced into or establishing in grain bins.

A few steps to reduce stored grain insects establishing in grain bins include:

  • Clean in and around storage facilities.
  • Inspect grain storage facilities for signs of deterioration, leaks or holes.
  • Clean equipment used to move grain. Combines, grain wagons, truck beds,
    augers and other equipment used to move grain should be cleaned of grain
    residue before being used.
  • Dry and cool grain (ideally below 15°C) as quickly as possible after harvest.

Controlling insects found in stored grain.

Knowing the species you are dealing with is important when determining the most effective and economical means of control. If it is a fungus feeder such as foreign grain beetle, practices that result in grain drying may be all that is needed.

For insects that feed directly on the grain, if the grain is being kept over the winter, lowering the grain temperature through aeration or moving the grain can kill stored gain insects.

Grain vacs, if used at a slow enough speed (such as 200 bushels per hour), can kill stored grain insects. Removing too large a volume of grain at a time results in the grain protecting the insects and reduces kill. Insect killing efficiency is greatly increased when a 90° angle is made in the grain vac pipe. The grain should be dry for this method to work well.

Depending on the crop being stored and insect pest, chemical control options can include fumigants (such as phostoxin or fumitoxin), diatomaceous earth (Protect-It, Insecto), or malathion. There are things that should be considered before using any of these chemical control options, however.

Fumigants such as phostoxin and fumitoxin are restricted to applicators with a valid stored agricultural products license. These products can not be used when the grain temperature is below 5°C, as the tablets release the gas too slowly.

Diatomaceous earth damages the cuticle of the insect, reducing the insect’s ability to retain moisture. The insect eventually dies from dehydration. It can take weeks for diatomaceous earth to control insects in grain bins, assuming the grain is dry.

Important note: Some commodities, such as canola, flax and sunflowers, should not be stored in facilities recently treated with malathion.

Integrated Crop Agronomy Cluster 2018-2023

The Integrated Crop Agronomy Cluster (ICAC) was designed to put focus on a whole-farm approach, it addresses critical gaps in research for farm management as a whole and does not put focus on one crop type or approach. There are seven research activities within the cluster, MCA participates in all research activities as they all bring valuable information to Manitoba producers. Each activity and a brief description are listed below, for more information, view the Integrated Crop Agronomy Cluster Summary 2018-2023.

Co-ordinated monitoring of field crop insect pests in the Prairies Ecosystem

Co-ordination of a crop disease monitoring network for Western Canada

  • Provides funding for the Prairie Crop Disease Monitoring Network.
  • Funds the activities to continue to provide timely information about crop diseases and highlight effective disease management approaches.

Developing a risk model to mitigate Fusarium Head Blight (FHB) in western Canadian cereal production.

  • Provides funds to develop a FHB risk map model that is based on data taken across the Prairies and takes into account over 500 weather stations to produce a user-friendly, online risk-mapping tool.

Management of glyphosate-resistant kochia in western Canadian cropping systems

  • Studied the effect of several different non-chemical ways to manage kochia, including crop rotation, row spacing, seeding rates and harvest timing.

Spray drift management under changing operational requirements

  • Studied how the machinery plays a role in creating spray drift.
  • This included quantifying drift as a function of travel speed, spray quality and boom movement.

Optimizing systems productivity, resilience and sustainability in the major Canadian ecozones

  • With increasing evidence that supports the benefits of diversifying crop rotations to ensure long-term sustainability, this project studied several different crop rotations at eight sites across the Prairies to determine the impact of different rotations on productivity, resilience and sustainability.

Economic and agronomic performance of emerging cropping systems for Western Canada

  • Looks at including soybean and/or corn in crop rotations in Western Canada (regions where this is not a traditional crop included in rotations) and the economic, agronomic and environmental impacts this will have.

First Wheat Retreat connects food influencers to Canadian wheat

Consumers play an important role in agriculture, and finding new ways to reach this audience is important.

With that goal in mind, the first ever “Wheat Retreat” brought about 30 influencers in the food and nutrition world together to explore all things wheat – nutrition, functionality and sustainability. 

The Wheat Retreat was hosted by the Canadian Wheat Nutrition Initiative, aka What About Wheat?, at Cereals Canada’s world-class facilities in Winnipeg on April 27-30, 2023.

Manitoba Crop Alliance (MCA) supports market development initiatives that provide value to our farmer members, so we sent Mallorie Lewarne, our former agronomy extension specialist – cereal crops, to add some perspective on farming in Manitoba.

The retreat included a tour of Cereals Canada’s technical facilities, a pasta sensory session, a hands-on sourdough workshop, a bannock making session and discussions about wheat farming.

“Everyone who attended had great questions – including plenty about agriculture. They asked lots about general farming practices, pesticide use, the wheat class system and more,” says Lewarne.

“These influencers are much more public facing than the typical farmer or agronomist. I think this was a great opportunity to connect and provide them with accurate information they can share with the general public.”

Sheila Elder, a delegate on our wheat and barley crop committee, and her husband Jeff attended one day of the retreat and gave a presentation that took attendees through a growing season as a farmer. 

They talked about seeding, scouting, spraying and harvesting, while focusing on technological advances that allow them to be more profitable and sustainable.

“I think there is often a disconnect between the farmer and the consumer,” says Lewarne. “Any opportunity we get to share accurate information about farming practices in Canada is invaluable, and these small opportunities can add up to make a large impact on that disconnect.”

What About Wheat? is a platform for nutrition professionals to find the latest science-based information on wheat to share with their clients and consumers. The information is vetted by a Scientific Advisory Council made up of researchers and registered dietitians.

Member organizations include Cereals Canada, Grain Farmers of Ontario, Alberta Wheat Commission, Manitoba Crop Alliance, Saskatchewan Wheat Development Commission and Canadian National Millers Association.

Derek Brewin is professor and head of the Department of Agribusiness and Agricultural Economics at the University of Manitoba (U of M). He earned his B.Sc. at the University of Alberta, followed by an M.Sc. at the University of Saskatchewan (USask) and PhD at Penn State University. Brewin has worked at U of M since 2003 and lives in Winnipeg, dangerously close to the best ice cream in the city. 

Where did you work before U of M?

I started this job after I finished my PhD, and before that I worked as a research associate at USask in the Strategic Development Fund. Prior to that I worked at the Canadian Wheat Board as a corporate advisor, a policy advisor for Agriculture and Agri-Food Canada (AAFC) and a lender for Farm Credit Canada (FCC). 

What got you interested in this area of work? 

There are so many opportunities in agriculture. Once I got the B.Sc., I kept getting wonderful offers. I was fortunate that FCC needed somebody like me when I came out of my program. Working and learning about how FCC forecasted prices led me to go back for my M.Sc. I thought I would return to work with FCC, but when I finished my degree there was an opportunity at the Prairie Farm Rehabilitation Administration (PFRA) in transportation policy, and once I got into policy I’ve stayed interested. 

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

I teach an agriculture marketing course where we evaluate the ag supply chain from the producer to the consumer. We know consumers are the main drivers, but ag supply chains are complex. To be able to work out the different steps in the beef, grain and oilseeds supply chain, or livestock supply chains, requires understanding of a lot of firms and agents.

When you’re thinking about the whole supply chain, the incentive to grow at the beginning, or the farmer’s bottom line, is a big part of why there is supply at all. This is something I’m always watching as part of my classes. I ask my students to think about what the price of canola is in Manitoba, for example, and how that factors into the price of the bottle of oil in a supermarket. Thinking about how those prices are all connected and how they cover the costs of processing to transporting helps us understand the market better. 

The Research to explore socio-economic impacts of disruptions on Agri-food supply chains and markets project, funded by Manitoba Crop Alliance, is about building capacity in this area, as there is growing demand for it. 

COVID-19 had a huge impact on food markets and in the food supply chains, there was a large shift from people eating out to buying retail and feeding themselves. That was definitely a big disruptor. The barriers put up during the protests of the grain supply chain at the beginning of 2020 also slowed down some grain transportation and led to backlogs in terms of movement. These are some of the areas we focus on for this research. Learning about current and historic disruptions, like the Great Canadian Grain Logistics Crisis of 2013-14, is what I teach to my students and what drives my research. 

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

Some of the evidence on public sector investment in agriculture shows that it pays off 40 to 1. I’ve done some research on innovation systems and I feel really good in terms of the economics of it. It can be a really slow process; sometimes it’s 40 years between when something is invented and when it has an impact on yield. I think, in the long run, farmers are going to be a lot better off for the research investments made through the check-offs. Economists need to keep checking that return on research as well as contribute in their own areas, especially in training new analysts. 

How does that farmer funding and support directly benefit farmers? 

For my work, we are looking backwards to learn. Learning more about these big interruptions through a few projects with Alankrita Goswami, we are collecting evidence from disruptions like BSE, COVID-19 and the transportation breakdowns in 2013-14. The more we understand these, we can work to determine whether or not current policy could help us get through a similar interruption. For us as economists, it’s a good thing to make sure the incentives have stayed in the right place to invest and monitor these systems in order to keep our supply chains functioning.

How do you spend your time outside of work? 

I enjoy reading about economics and international economics, as well as history and historical fiction; I really enjoy books by James Michener. I like playing old-timer hockey, curling and occasionally camping. Every year I go on a pretty serious canoe trip, a tradition that began back during my master’s.

How do you celebrate agriculture?

The first thing that came to mind was working the calves at fall. Some of our own work was tough sledding with just my dad, brother and I. But sometimes we would tackle the calves as a community with friends from the bigger ranches and we had calf weaning/branding events. It was a real celebration of the year’s calf crop and everybody getting together in a very traditional way, one they were doing 200 years ago and are still doing today. For me, that is a special event and a way to celebrate agriculture. 

Who or what inspires you?

I’ve met some leaders in the agriculture sector, some students included, who really inspire me – some who have received awards of merit from the faculty here. These leaders come in to be celebrated and receive these awards, and we get to hear their stories and all about their great careers. It’s nice to hear how people have changed the Manitoba sector, and it’s really inspiring for our students.
