New fall-application registration for extended-control herbicides in Canada

FMC’s Authority^® 480 herbicide, Authority^® Supreme herbicide and PrecisionPac^® SZ-75 herbicide are now registered for fall application.

″FMC is constantly working to improve labels to offer farmers different application opportunities,″ says Jordan Brisebois, FMC product manager, extended weed control and grower programming. ″This fall, registration provides the opportunity for growers to spread out their workload between the fall and spring. Additionally, applying these products in the fall creates the environment for consistent, high-performing weed control.″

Authority^® brand herbicides and PrecisionPac^® SZ-75 herbicide create a powerful, soil-based defence. When applied in the fall, each of these herbicides remain inactivated on the soil surface through the winter. The herbicides are then activated with snow melt in the spring, creating a soil barrier to weed emergence.

″Keeping fields clean during the critical weed-free period is essential to crop establishment,″ says Brisebois. ″Now growers have the flexibility to apply these products when it fits their farm schedule and agronomic needs. These three extended weed control products control germinating weeds, which significantly reduces competition for water and nutrients.″

Authority^® brands and PrecisionPac^® SZ-75 herbicide are known for industry-leading performance on hard-to-control weeds like kochia. Growers now have increased flexibility as to when they apply these products so they can choose the timing that words best for their particular operation. Also, each brand is registered for pre-seed application to a multitude of crops.
