The Agronomists, Ep 29: Joanna Follings and Kelly Turkington on fusarium head blight management
by RealAgriculture Agronomy Team
The winter wheat in Ontario is ready to be staged for fusarium head blight (FHB), and with such an impactful disease, we figured it was important to bring some guests on to talk about it!
Taking us on this journey with host Lyndsey Smith is Joanna Follings, cereal specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) and Kelly Turkington, plant pathologist with Agriculture and Agri-Food Canada (AAFC) at Lacombe, Alta.

It’s that time of year where growers are getting into the field in Ontario for FHB spraying on winter wheat crops
Heading started in Ontario about two weeks ago
Ask yourself what your pants look like when you are walking through the field moisture-wise. Do they have moisture on them at 10 am still? 11 am? This is a way to gauge the humidity.
Starting to hear reports of leaf spot complex in wheat and barley right now in Alberta. Right now leaf rust and stripe rust reports are low
Strong winds and severe weather events are bringing up concerns for bacterial leaf streak
Physiological fleck in wheat is rearing its head in Ontario again
What causes the physiological fleck to happen? We actually don’t know. Researchers are working on it.
Spoiler alert: a “day” with staging your crop isn’t necessarily a days worth of time
Day zero is when 75 per cent of the heads have emerged
If it’s a really hot dry year, day 1 or day 2 can happen within a couple of hours. This is why it is so critical to scout fields. (Can we really say it enough? SCOUT!)
Targeting the timing can be extremely difficult
The anthers will always begin in the middle of the wheat head
Powdery mildew can be a big issue in a dry year. Be sure to check for that too. We want to keep those leaves “green and clean.”
Our first line of defence against FHB is a variety with some sort of moderate resistance.
What about un-pollinated florets? Could open up the risk of ergot. Frost could have caused some floret losses, and you’ll see bleached heads, or bleached awns. So far in Ontario this doesn’t seem to be a concern.
Where do you go for the latest in beef production information? What drives you to make changes on your operation? The Beef Research School is one of these tools, yes, but most ranchers and feedlot operators draw knowledge from conferences, extension staff, neighbours and online and hard-copy research.
