Gramoxone Phase-out, Safe Use and Stewardship Changes

PMRA has completed a special review on Paraquat (Gramoxone Liquid Herbicide) and proposed a phase-out of the product. See part of the decision below:

Health Canada’s Pest Management Regulatory Agency (PMRA) recently conducted a Special Review of Paraquat and concluded that changes to the Gramoxone® Liquid Herbicide with Wetting Agent, Reg. No. 8661   (i.e. “Gramoxone”) product formulation and packaging are required. As a result of this decision, a phase-out of the current product is being implemented. 

As mandated by the PMRA, Syngenta will not be selling Gramoxone (in its current form) after March 31, 2017.  The last date that retailers can sell this product is September 30, 2017. 

Growers may continue to use the current formulation of Gramoxone during the 2017 and 2018 seasons. After December 31, 2018, this formulation of Gramoxone must not be used and must be properly disposed of. Please contact CleanFarms (1-877-622-4460) for information regarding the pesticide disposal program in your area.

 Options to make this tool available to Canadian growers beyond December 31, 2018, are currently being considered and evaluated. We will update you in the future, as appropriate.

In order to continue to use Gramoxone for 2017 and 2018, there are additional stewardship requirements that must be met:

  • Gramoxone may only be sold to and used by individuals that hold an appropriate pesticide applicator certificate or license as recognized by the appropriate provincial/territorial pesticide regulatory agency.
  • See amended label for changes in PPE and first aid instructions.
  • Gramoxone may only be tank-mixed with products on the label.
  • Retailers must provide a copy of the Paraquat Stewardship Counter Card to the end-user (i.e. grower, applicator, etc.) at the time of sale.

These Stewardship requirements can be found on the Gramoxone Product Page, short Video and Powerpoint Presentation.
