In recent years, the wheat midge fly has caused significant damage to wheat crops in Western Canada. Fortunately, new midge-tolerant wheat varietal blends are available to wheat growers.
Using SRC’s midge-tolerant wheat refuge testing service, wheat growers can ensure they have the right blend to help protect their crops from a virulent wheat midge population.
The Canadian Seed Growers Association (CSGA) recognizes that test results from SRC Biotechnology Laboratories are reliable for verifying the percentage refuge frequency in seed samples from midge-tolerant wheat seed crops required by Additional Certification Requirements for CSGA crop certification.

Sample Procedures and Form
Download the Midge Sample Procedures and Form for more information about submitting samples.
Our lab requires 500 g of untreated blended wheat per sample. Ideally, taking multiple midstream samplings while transferring grain is the best way to acquire a representative sample. Avoid sampling from the bottom of a bin as this may bias the sample towards one variety.
The Midge Tolerant Wheat Stewardship initiative aims to mitigate the risk of crop damage by confining the use of farm saved seed to one generation past the Certified seed class. Adherence to the stewardship program ensures the viable use of midge-tolerant wheat varieties for years to come, while reducing losses from a pest that is difficult to monitor and expensive to control.
