Farmers are being advised to look for any damage from the wheat stem sawfly.

It's the larvae from those adults that do the real damage by feeding within the stem and weakening it.

Provincial Insect Specialist, Scott Hartley says if there is 16 % to 17% of the crop affected, producers should be considering an early swath.

Hartley says the best method of control for the wheat stem sawfly is the plant solid stem varieties.
