Some interesting work is being done on the control of richardson ground squirrels or gophers.
Many areas have seen heavy pressure with the dry conditions over the last couple of years
Insect and Vertebrate Pest Management Specialist James Tansey says a key tool for control "strychnine" has been deregistered, noting that after March 4, 2023 it will be illegal to use.
"Because of this impending loss of a pretty valuable tool for Richardson's ground squirrel control, we decided to look at some of the other registered control products. These include a couple of zinc phosphide products in a ready to use formulation. We also looked at a couple of anticoagulant formulations that is Rozol ready to use and Ramik Green which is also a ready to use formulation."
He notes in Saskatchewan the testing was done around the RM of Maple Creek, an area with a high richardson ground squirrel population.
