Researcher believes plant growth regulators are worth a try

Mar 08, 2023

Research being conducted on plant growth regulators (PGR) show the product can help a cereal crop but there are no guarantees.

There has been increased use of these products on the prairies, according to Dr. Breanne Tidemann, a research scientist with Agriculture and Agri-Food Canada based in Lacombe, Alta.

Tidemann said PGRs are chemicals that are applied to plants that change how they grow. In western Canadian agriculture, it is typically used to shorten the plants and then reduce their chance of lodging in field crops.

“Wheat and barley in particular are the two that we’re using them on, and the goal is to be able to up nitrogen rates and still get some increased yield, but not get the increased height with the plants falling every which way that we sometimes see when we do that,” Tidemann said.

Video: Why Invest in Canada’s Seed Future? | On The Brink: Episode 3

Darcy Unger just invested millions to build a brand-new seed plant on his farm in Stonewall, Manitoba so when it’s time for his sons to take over, they have the tools they need to succeed.

Right now, 95% of the genetics they’ll be growing come from Canadian plant breeders.

That number matters.

When fusarium hit Western Canada in the late 90s, it was Canadian breeders who responded, because they understood Canadian conditions. That ability to react quickly to what’s happening on Canadian farms is exactly what’s at risk when breeding programs lose funding.

For farmers like Darcy, who have made generational investments based on the assumption that better genetics will keep coming, the stakes are direct and personal.

We’re on the brink of decisions that will shape our agricultural future for not only our generation, but also the ones to come.

What direction will we choose?

On The Brink is a year-long video series traveling across Canada to meet the researchers, breeders, farmers, seed companies, and policymakers shaping the future of Canadian plant breeding. Each week, a new story. Each story, a piece of the bigger picture.

Episode 3 is above. Follow Seed World Canada to catch every episode, and tell us: Do you think the next generation will have the tools they need to success when they takeover? How is the future going to look?
