Wheat stem sawfly survey shows moderate to high levels for Saskatchewan’s brown soil zones

If you’re looking for resources surrounding how high the risk is for wheat stem sawfly across Saskatchewan — look no further, as the maps formed by surveys have been released.

Alongside in-season scouting, the maps help producers determine when and if management is needed for the perennial pest of wheat in Saskatchewan.

The formal survey of wheat stem sawfly began in early 2023, showing moderate-to-high levels of cutting throughout the brown and dark brown soil zones.

The survey, which was conducted on behalf of the Saskatchewan Wheat Development Commission and the Government of Saskatchewan, suggests a hot spot of the pest near Moose Jaw, Sask., and the central and east-central regions.
