Pest Surveillance Initiative (PSI)

We use advanced crop pathology diagnostic methods- including DNA markers and Spore Imaging– to identify pests threatening your crops.

Why Test Your Field?

Accurately identifying and quantifying the pathogen type helps growers select the most appropriate management tool to address the problem before it impacts yield and profitability. In addition to advanced crop pathology diagnostic methods including spore imaging, PSI uses an increasing number of DNA based tools to determine the race or pathotype of the pathogen that may be present- key knowledge for maximizing genetic resistance traits in varieties. Monitoring the presence and levels of pathogens in the field provides ‘early warnings’ of emerging pests.

About the #GetTested Program

Manitoba Canola Growers Association Members can get free testing for clubroot, Blackleg race and Verticillium stripe on all their fields.

Testing for Glyphosate resistant Kochia and Tier 1 Noxious Amaranth Species is available as a fee-for-service test.

When to expect test results:

Please allow 10 business days from when PSI receives the sample for return of test results.

Any questions- contact us!

Testing Services

We test for presence of the following:

  • Clubroot
  • Blackleg
  • Verticillium Stripe
  • Glyphosate Resistant Kochia
  • Tier 1 Noxious Amaranth Species ID
Genetic testing for glyphosate resistance in kochia is rapid and can be done in season.

Did you know…

Glyphosate-resistant (GR) kochia results from a type of mutation called target site amplification- basically the plant makes more than the normal number of copies of the enzyme in the plant that glyphosate attacks- this is how glyphosate kills the plant.  More copies means the plant can continue to grow and survive after spraying- although the plant may be weaker and not produce as much seed.  This gives a competitive advantage to these plants and they can increase rapidly- meaning using glyphosate alone actually results in more resistant plants ‘appearing’ in the field. 

PSI’s test measures the approximate number of ‘copies’.  Higher number means more tolerant to glyphosate. For context, PSI has tested samples that had more than 90 copies per plant.

Check out the sampling video for information on how to collect samples in the field and then submit the sample for testing.
