After facing significant delays, the official window for strychnine use in Alberta and Saskatchewan opened on Wednesday. Farmers are now permitted to utilize the controversial rodenticide to manage Richardson’s ground squirrels, commonly known as gophers, until September 1. However, limited availability and concerns regarding the product’s efficacy at this late stage of the year are causing complications.
Strychnine was granted approval for controlled and time-limited emergency use in Alberta and Saskatchewan after extensive lobbying efforts by these provinces, following its ban by Health Canada two years ago due to environmental risks. The Alberta government estimates that gopher infestations in the province pose a risk of over $800 million to hay and pastures annually.
Under the Pest Control Products Act, producers in Alberta and Saskatchewan can use strychnine until November 2027, but it is restricted to specific seasonal windows. The anticipated spring application window, from March 1 to June 15, was missed due to supply chain challenges faced by Agromax, the sole authorized manufacturer of strychnine in Canada.
Although the product has now reached eligible municipalities in Alberta and Saskatchewan, demand often surpasses supply. Some regions like Wheatland County and Flagstaff County are resorting to lottery systems to determine which producers can purchase strychnine, while others, like the Municipal District of Wainwright, have decided not to offer strychnine this year due to the late season and limited availability.
Experts advise that early spring is the optimal time for strychnine use, as gophers are more likely to consume the bait when natural food sources are scarce. Concerns regarding the effectiveness of strychnine during this period have led some producers to hold off on using it until next year.
Ongoing advocacy aims to extend the special use approval for another year, as this season is perceived as somewhat of a “write-off.” The federal government emphasizes the importance of responsible use to protect the environment, species at risk, and public health during the authorized application window from July 15 to September 1.
Despite its historical use as a primary gopher control solution, strychnine was phased out by the federal government in 2020 and subsequently banned in 2024 due to environmental risks. Conservation specialists warn about the potential impact of strychnine on predator species and unintended consequences, such as the deaths of animals like dogs.
While the new strychnine program is accompanied by strict requirements and environmental protocols, concerns persist regarding the decision-making process and the lack of scientific evidence supporting its use. The Alberta government suggests exploring alternative methods for gopher control, such as legal pesticides, fumigation, and promoting natural predator activity.
In conclusion, the debate over strychnine use for gopher control continues, with stakeholders emphasizing the need for sustainable and environmentally friendly pest management practices in agriculture.
