Testing Services

PSI uses sensitive DNA-based methodology to detect the presence and amount of crop pests in the environment. We are currently testing for low levels of clubroot; glyphosate resistant (GR) kochia, Amaranth species, Blackleg races and Verticillium stripe.


If you’d like to submit a sample from your field for testing, please choose from one of our testing services below. Tests must be prepaid through PayPal by completing the order process. MCGA members are eligible to receive FREE testing on all their fields for clubroot, Blackleg race and Verticillium stripe. For more information, click here. Testing for glyphosate-resistant kochia and Amaranth species ID is available as a fee-for-service test.

NOTE: MCGA members need to use the ‘cart’ to check out; the free testing coupon will be applied to clubroot, Blackleg Race and Verticillium stripe test requests only. You may add more than one type of test to the cart in one order.

Upon completion of your order, Pest Surveillance Initiative will send you shipping instructions. If you have any questions, please do not hesitate to contact us.
