Saskatchewan Expands Emergency Use of Banned Pesticide Strychnine for Gopher Control
The Saskatchewan government has announced a significant expansion in the emergency use of strychnine, a banned pesticide, to manage gopher populations across the province. This decision comes after Health Canada's Pesticides Regulatory Directorate approved a request to extend provisional authorization, allowing farmers in 208 rural municipalities (RMs) in southern and western Saskatchewan to use the chemical on a temporary basis until November 2027.
Background and Approval Details
Strychnine, a highly toxic rodenticide that affects the nervous system of animals, was banned in 2024 by Health Canada's Pest Management Regulatory Agency (PMRA). However, due to abnormally dry conditions and a surge in Richardson's ground squirrel (RGS) populations, Saskatchewan and Alberta lobbied for a reversal. In late March, it was announced that farmers in certain Prairie regions could use strychnine temporarily, and this approval has now been amended for the second time in under two weeks.
The expansion applies to areas most affected by gophers, with the provincial government citing multi-million dollars in crop damage from the recent spike in RGS populations. Agriculture Minister David Marit stated, "We heard from farmers and ranchers that further expanding the eligible area was necessary. This change better reflects regions with the highest Richardson's ground squirrel populations and ensures producers have access to the right tools to manage this pest."
Impact and Geographic Scope
A total of 208 RMs will now have access to two percent liquid strychnine, specifically targeting regions where gopher infestations threaten agricultural sustainability. Health Canada explained that the temporary use aims to address the significant damage caused by these pests, which have become a serious threat to a variety of crops due to the dry conditions.
Risk Management and Safety Measures
Concerns about the dangers of strychnine, including risks to scavengers and pets, have been addressed in the government's news release. The revised Emergency Use Registration includes enhanced measures to protect species at risk, such as:
- Increased monitoring and carcass collection
- Disposal requirements
- Enhanced mandatory training for users
Additionally, the Ministry of Agriculture is developing a Strychnine Stewardship Program in partnership with the Saskatchewan Association of Rural Municipalities (SARM) to ensure safe and responsible use. This program aims to mitigate environmental and health risks while supporting farmers in pest management efforts.
Conclusion
The expansion of strychnine use in Saskatchewan highlights the ongoing challenges faced by farmers in managing pest populations amid changing environmental conditions. With strict safety protocols in place, this emergency measure seeks to balance agricultural needs with environmental protection, providing a temporary solution to a pressing issue in the province's farming communities.
