Canola and mustard growers on the Canadian Prairies will have a new seed treatment for the 2027 season. Syngenta has introduced Curanza to protect the two crops from cutworms and from crucifer and striped flea beetles, and it is available now through CANTERRA SEEDS and BrettYoung.

What sets the product apart, the company says, is the dose of its active ingredient. "Curanza's claim to fame is the rate of cyantraniliprole," Justin Bouvier, product lead for Seedcare at Syngenta Canada, told Farms.com. Curanza carries 800 grams of cyantraniliprole — a Group 28 insecticide — per 100 kilograms of seed, against competitor products with rates of up to 500 grams. "It gives farmers better control over flea beetles plus the added protection from cutworms," Bouvier said.

The pests are expensive. Research data from Agriculture and Agri-Food Canada and the University of British Columbia released in 2025 put the economic impact of flea beetles in canola at more than $160 million, cutworms across all crops at about $11 million, and total insect damage across the Prairies at more than $200 million.

Syngenta tested Curanza in plots across Manitoba and Saskatchewan between 2023 and 2025. Compared with competitor products, the trial data show 2% less flea-beetle damage at 20 days after emergence and 3% more plants at six days after emergence. BrettYoung tested Curanza alongside Helix Saltro this summer but has not yet published results.
