Bayer launches potato herbicide

Bayer has announced the launch of Sencor STZ, an innovative new herbicide for broad-spectrum control of all major annual grass and broadleaf weeds in potatoes. The acronym STZ stands for the active ingredient sulfentrazone, a group 14 herbicide.

Sencor STZ combines the trusted control of Sencor with a new Group 14 mode of action, providing Canadian potato growers a new weed control option for their fields and offering a convenient resistance management tool. As a pre-emergent herbicide, Sencor STZ has uptake through the roots and shoots of weeds, providing early-season weed control during critical crop stages. The product works on emerged weeds and provides residual broad-spectrum control of weeds yet to germinate. It will be provided in a convenient co-pack.

“As the first innovation in the potato herbicide space in many years, Sencor STZ offers an exciting new tool for Canadian potato growers to combat a wide spectrum of weeds and maximize crop yield,” says Jon Weinmaster, crop and campaign marketing manager, Horticulture & Corn at Bayer. 

Sencor is a proven performer that delivers reliable broad-spectrum weed control to Canadian potato growers. Trials utilizing Sencor STZ have demonstrated efficacy against Group 2- and 7-resistant biotypes, while providing essential control of Group 5-resistant broadleaf weeds, demonstrating the added benefit of the product’s Group 14 herbicide.

“Given the increasing occurrence of herbicide resistance and a potentially shrinking number of solutions available for combatting tough-to-control weeds, Sencor STZ presents a welcome opportunity for growers to ensure they have the crop protection they need,” says Weinmaster. “This new herbicide affirms Bayer’s position as a leader in potato solutions and our commitment to growing and furthering innovation within horticulture.”

Sencor STZ will be available to potato growers in Eastern Canada and British Columbia for the 2018 season. Sencor STZ comprises Group 5 (metribuzin) and Group 14 (sulfentrazone) herbicides.

For more information regarding Sencor STZ, growers are encouraged to talk to their local retailer or visit
