The use of strychnine for gopher control has officially started in Alberta and Saskatchewan after significant delays.Farmers can now use the controversial rodenticide to manage Richardson's ground squirrels until September 1, but concerns about its effectiveness late in the season and environmental risks persist.The emergency authorization, granted after lobbying by the provinces, allows use until November 2027, but seasonal windows are strictly regulated.The spring application window was missed due to supply chain issues with Agromax, the sole manufacturer.

Some municipalities, like Wheatland County, are using lotteries to allocate limited supplies, while others, such as Wainwright, have opted not to distribute strychnine due to its reduced efficacy and the gophers' estivation period.

Conservationists warn of environmental impacts, including risks to swift foxes and burrowing owls, and highlight that previous use led to unintended ecological consequences.Alternatives like legal pesticides, fumigation, and promoting predator activity are being promoted by the Alberta government.

The federal government emphasizes balancing pest control with environmental protection, but critics argue the decision lacks sufficient scientific evidence.
