A new Group 14, non-selective herbicide that has activity on grasses is available for growers to use in burndowns.
Dale Ziprick of Gowan Canada said Insight Liquid SC is a PPO inhibitor that is typically mixed with glyphosate for pre-seed applications ahead of spring wheat, corn and soybean.
“It’s been launched in other parts of the world, but this is a brand-new active ingredient for the Canadian market,” Ziprick said.
“It’s in a convenient liquid formulation. If you apply it at the 60-mil rate, which is our recommendation especially if you have wild oat, one jug that’s in our pack size for the launch will treat 40 acres.”

Gowan Canada is the Canadian distribution of Insight Liquid SC, which was developed by Ishihara Sangyo Kaisha (ISK) and Farm Hannong out of Korea.
Insight Liquid SC was granted registration for use in Canada last September and Gowan Canada launched marketing material at the Crop Production Show in Saskatoon in January.
Ziprick said Insight Liquid SC is a contact herbicide that achieves a quick kill on any weed it touches.
“The active ingredient is called Tergeo (brand name for tiafenacil). So, it’s similar to other Group 14s in the marketplace with regards to having very ultra-fast burned down,” Ziprick said.
“But unlike other Group 14 products in this category, we’ve got grassy weed activity. For the 2023 season we’ve got wild oat control on the label, plus a number of important broadleaf weeds like kochia, red root pigweed, common lamb’s quarters, wild buckwheat, and volunteer canola.”
He said the ability to control wild oats will help prevent wild oats from developing resistance to glyphosate.
“This now enables producers to start to take a long-term risk management approach to offsetting glyphosate resistant wild oat on the Canadian Prairies. When you look at some of the data generated by Agriculture Canada through their weed surveys, they’re predicting that wild oat could be one of the next glyphosate resistant weeds on the Prairies,” Ziprick said.
