Ana Badea, PhD is a Barley Breeding and Genetics Research Scientist for Agriculture and Agri-Food Canada (AAFC) at the Brandon Research and Development Centre (BRDC). Badea earned her Ph.D. degree from the University of Agricultural Science of Timisoara, Romania, in Plant Breeding and Genetics in 2003. Her Ph.D. research was mainly focused on the development of two-row winter malting barley.

Where did you work before the AAFC-BRDC?

In 2004 I joined AAFC at the Lethbridge Research and Development Centre (LeRDC) in Alberta as a visiting fellow. I moved to AAFC-BRDC, in Brandon, Manitoba in 2012 as the new barley breeder for the Six-Row and Hulless Barley Breeding Program. In 2017 I was entrusted with the leadership of AAFC’s flagship barley program: the Two-Row Barley Breeding Program.

What got you interested in this area of work?

I’ve always been interested in plant biology and genetics, but I’ve always wanted to help people around me and make a contribution to society. From a young age it was very clear to me I wanted to do something where I am connected to the land, which is why I chose to enroll in the University of Agricultural Science. In my first year of university, I was accepted to be a member of the “Breeding and Genetics Club”. It was there I discovered plant breeding, a perfect career choice for me as it allows me to do everything I’ve always wanted to do, and even more! As a barley breeder my main goal is to develop improved varieties. One of the best things is seeing farmers adopt these new varieties and as a result get better quality and yields.

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

As the AAFC-BRDC Two-Row Barley Breeding Program leader I work with a team of dedicated colleagues to develop cultivars for three different barley classes; two-row malting, two-row feed and two-row hulless for food for western Canada, where more than 90% of Canada’s barley is grown. A new stream of barley cultivars is continuously required to keep up with emerging disease problems and changing environmental, economic and market conditions so producers and the industry remain competitive.

I’m involved in several research projects focusing on biotic and abiotic stresses in barley and barley genomics. For example, our team has recently released the first barley reference genome of a Canadian barley cultivar. A genome is the genetic code of a living organism, so if we understand its genetic code, we can better predict how the crop will perform allowing us to select those favourable traits more precisely. These traits –yield, disease resistance or quality – will make barley more profitable.

Another aspect of my role is helping cultivate the next generation in agriculture by training students and graduate students. Every year our breeding program offers high-school and undergraduate students the possibility for shadowing, or internship opportunities in the lab and/or the field. Training the next generation is very important since it helps develop a solid, skilled workforce.

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

Barley breeding is a long-term effort that requires a strong commitment and support. Through the years farmers have provided guidance and funding that helped breeding programs stay focused to deliver on proposed targets. Farmer funding is critical for the success of the AAFC-BRDC barley breeding program. The funding helps our program make breeding plans that extend a little bit further enabling us to evaluate a larger number of breeding lines and capitalize on innovative research opportunities. It provides stability allowing us to maintain long-term, highly qualified, technical staff working on various activities required to develop new barley varieties.

How does that farmer funding and support directly benefit farmers?

On the breeding side, our ultimate goal is to deliver improved, field-ready barley cultivars that promote sustainable agriculture and help make farming operations more efficient and cost effective. Once we register a new cultivar it gets licensed to a seed distribution company and then made available to farmers. The process is a bit slower for malting barley since new cultivars need to undergo market development first. However, as seen in the past, the use of improved barley varieties often translates to increased revenue at the farm gate, lower risk and reduced variability for the barley grower’s income. Access to new and improved cultivars supports Canada to maintain its leading position as a premium barley supplier and, we like to believe, improves the competitiveness and profitability of our barley farms.

On the research side, a project that is very close to my heart is the Research on the Farm* new malt barley varieties led by the Canadian Malting Barley Technical Center in collaboration with Manitoba Crop Alliance. This project is a “win-win.” It allows me as a breeder to be in direct contact with the producers to receive feedback first-hand on our new varieties and better understand what needs to be improved upon next. The project gives farmers access to the newest genetics and helps determine the profitability of producing malting barley on their farm.

*The Research on the Farm Program collects data from real, working farms in order to test new practices or products over a wide range of farming environments to help guide management decisions. For more information visit https://mbcropalliance.ca/projects/on-farm-research-program.

How do you spend your time outside of work?

These days our family does long evening walks into the forest near Brandon. It is a real treat to see the forest transforming each season! Another activity our family enjoys is baking different types of bread and treats. Of course, most of them are being made out of the unmistakable, delicious nut-like flavour of barley flour. One of our family’s go-to treats is blueberry barley muffins. What better way to start your weekend mornings!

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

One thing that always stuck with me is what my grandfather, a hard-working farmer, told me one day when we were coming back from the field. I was quite young then, but I do remember how serious he was when he told me this: “Never forget to always be respectful to the land and the animals on your farm. They are the ones feeding you.”

What gets you excited about the work you do?

Many things excite me related to my work and it is difficult to narrow them down. If I had to, seeing the new cultivars adopted by producers and end-users, the versatility of the barley crop and the barley community are ones that come to mind first. The national and international barley community is a very exciting group to be part of. There is a lot of passion around barley and its products. Like one of my colleagues will say: “There is nothing better than a great cold beer in the summer or a hearty hot barley soup on a cold winter day”.

Growth Stage and Herbicide Application

Herbicide applications are well-underway in corn, including tank-mixes. Fields should always be scouted before any herbicide application for weeds present, precise crop staging and environmental conditions that could have an affect on efficacy.

Applying a herbicide at early growth stages provides greater crop safety, in most cases. The corn plant has a smaller surface area to be in contact with the herbicide, which means a smaller risk of damage. Herbicides with active ingredients like 2,4-D or dicamba can need to be applied to the crop as early as possible for this reason: the larger the crop, the greater the plant surface area and the greater the risk to the crop. It is very important to refer to all herbicide labels and contact appropriate companies with any questions prior to applications.

Refer to Manitoba Crop Alliance’s Vegetative Growth Stage ID factsheet for staging tips.

Also available is a Quick Herbicide Reference Guide for current pre-emergent and post-emergent herbicides on the market in Manitoba.

Quick Herb Ref Guide

Post-emergent herbicide application tips: (for full list, visit https://www.dekalbasgrowdeltap…)

  • ALWAYS READ AND FOLLOW LABEL DIRECTIONS.
  • Corn under stress may not have the ability to metabolize some herbicides quickly enough to avoid crop injury. Weeds under stress may not may not accept the herbicide to its full capacity.
  • Spray additives can increase the rate of herbicide uptake by the crop.
  • Herbicide residues from previous applications may remain in the spray tank causing contamination.
  • Post-emergent herbicide injury symptoms can include leaf chlorosis or necrosis, onion leafing, internode stacking, rat tailing, ear pinching, ear bottlenecking, brace root malformation, and green snap.

Flax: Emergence and Frost

Frost Impact on Flax

Flax plants just emerging (cotyledon stage) are the most susceptible to early spring frost, but can withstand temperatures down to approximately -3° Celsius. After the seedlings have passed the two leaf stage and are hardened by exposure, they can withstand temperatures as low as -8°C for a short time, without significant damage (https://flaxcouncil.ca/growing…).

Flax is generally at the first whorl stage right now, so a hard frost can have significant damage on the crop. It is important to follow the typical frost scouting techniques and wait 3-5 days to see whether frost has impacted the crop or not.

Emergence Monitoring (posted by SaskFlax: https://www.saskflax.com/quadr…)

One way to work towards optimizing flax performance on your farm is to determine the plant population and calculate emergence rate. Relating these numbers back to the seeding rate used, the environmental conditions and other factors at seeding can help determine management practices for the growing season and adjustments that can be made next year.

Steps to determine actual plant population and emergence rate:

1. At 1.5 to 2 weeks after seeding, count the number of plants per square metre or foot in a few representative locations in the field and calculate the average. This number is the plant population. To maximize yield potential, the minimum desired population for flax is 300 plants/m2 (28 plants/ft2) and the maximum is 400 plants/m2 (37 plants/ft2).

Sunflower Frost Tolerance

Frost Tolerance

Sunflowers are fairly frost tolerant up to the V4 or 4 leaf stage. The cotyledons just emerging are most frost tolerant, with risk of injury increasing as the plant adds leaves. If sunflowers become brown or black and the terminal bud is severely damaged, plants will not recover. Less severe frost damage may result in loss of apical dominance and plants will exhibit branching from axillary buds, resulting in multiple heads later in the season.

Tolerance to frost in sunflowers can be influenced by the hardening off process. If it is cool or cold for several days previous to the frost, seedlings may have better tolerance to lower temperatures. (https://www.gov.mb.ca/agricult…)

Plant Population

As the crop appears to be fully emerged in the late VE staging, it is a great time to do population counts to determine planting accuracy. Not all sunflower plants may have emerged at this stage, which makes timing appropriate. If the majority of the crop has emerged, a producer should be assessing what percent of the crop remains below the soil surface and why they are behind the rest of the crop. Dry soil, poor seed to soil contact, and consistent planting depth were all planting issues that have to be contended with in extremely dry planting conditions. Go out to the field and do some plant counts now to determine what may have gone wrong just a few weeks ago. Assessing a planting situation at harvest is not the time to learn from mistakes or environmental challenges.

To estimate plant population of emerged crop, determine the length of 1/1,000th acre using the table below (http://corn.agronomy.wisc.edu/AA/A033.aspx). Measure that distance out and count how many plants have emerged. Record the number. Repeat this 10 times at random locations to get an estimated average of final plant population.

This is also the ideal time to be scouting for cutworms. John Gavloski, provincial entomologist with MARD, suggests scouting to make sure some cutworms are present before applying an insecticide. This time of year there can be a lot of natural enemies emerging. One John sometimes finds in high numbers early in the season is a small ground beetle called Bembidion, that can be very good at keeping levels of some other insects down. John warns that it would uneconomical to take out populations like these if the cutworm population was low. The take home message with early cutworm control is to always scout before applying an insecticide and avoid the proactive insecticide application.

Corn Emergence – Early Concerns

SPRING FROST:

Late May consistently brings early frost concerns in all crops. Corn is quite tolerant of temperatures below freezing because the growing point remains below ground until V6 approaches, however, if air temperatures dip below -2oC for more than a few hours, it is possible for the growing point to be damaged. See Is Corn Susceptible to Spring Frosts for temperature and scouting details following a spring frost event.

COLD BANDING:

Due to typical warming, followed by cooling spring temperatures as the corn crop was emerging, at VE and V1 staging it is possible to see cold banding on seedlings. As elongation occurs below the soil surface during warm conditions, a period of chilling can create a few growth issues. Most common is imbibitional chilling injury, which is the twisting or corkscrewing of corn mesocotyl as it is trying to emerge. This is when seed has imbibed (absorbed) the water required for germination and then the soil cools to temperatures below 10oC for prolonged periods. Cold banding is when air temperatures drop to 5 – 10oC and plants close to the soil surface get a yellow band across the leaf tissue. This is not cause for concern, but a common site at this time of year when temperatures bounce around.

PLANT POPULATION:

As the crop appears to be fully emerged in the late VE staging, it is a great time to do population counts to determine planting accuracy. Not all corn plants may have emerged at this stage, which makes timing appropriate. If the majority of the crop has emerged, a producer should be assessing what percent of the crop remains below the soil surface and why they are behind the rest of the crop. Dry soil, poor seed to soil contact, and consistent planting depth were all planting issues that have to be contended with in extremely dry planting conditions. Go out to the field and do some plant counts now to determine what may have gone wrong just a few weeks ago.

Measure that distance out and count how many plants have emerged. Record the number. Repeat this 10 times at random locations to get an estimated average of final plant population.

WEED CONTROL:

The first in-crop herbicide applications can occur at VE in glyphosate-tolerant corn. Due to the dry conditions prior to May long weekend, weed emergence was slow. Following varying rainfalls, weeds will likely be germinating quickly now, so it will be important to stay ahead of weed pressure. See MCA’s Quick Herbicide Reference Guide to see what can be applied and when for certain weed spectrums. It is always recommended to refer to the herbicide label for complete information or Manitoba’s Guide to Field Crop Protection prior to all applications.
