Wheat stem sawfly fall scouting

Harvest is the perfect timing to look for wheat stem sawfly larvae in the stems. The larvae, feeding on pith inside of wheat stems, affects crop yield and quality. Tip for scouting is pulling wheat plants, splitting the stems open and looking for an S-shaped larva. Pay closer attention to the areas that seem lodged, or have stems completely broken off above ground.

Refer to the risk maps from previous years for the general risks in your area.
