Coragen now registered on green onion subgroup via Minor Use Program

Adapted from original article by J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of several URMULE registrations for Coragen Insecticide for control/suppression of several Lepidopteran pests of  the green onion subgroup in Canada. Coragen Insecticide was already labeled for management of a number of insect pests on a wide variety of crops in Canada.

These minor use projects were submitted jointly by Agriculture & Agri-Food Canada’s Pest Management Centre (AAFC-PMC) and US IR-4 as a result of minor use priorities established by growers and extension personnel in Canada and the US. Management of Lepidopteran pests on these crops has been a priority of producers.

The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Coragen Insecticide.

Coragen Insecticide can be used for control or suppression of several caterpillar pests on the following crops as outlined below:

  • Control of cutworms, suppression of leek moth on GREEN ONION SUBGROUP
    • The green onion subgroup (3-07B) includes some specialty vegetables.  Labelled crops include: Leek, green Onion, Welsh Onion (tops), Shallot (fresh leaves), Chive (fresh leaves), Chinese Chive (fresh leaves), Elegans hosta, Fritillaria, Kurrat, Lady’s leek, Beltsville bunching Onion, fresh Onion, macrostem Onion, tree Onion (tops), and Wild leek.  Specialty vegetables may have different common names depending on the region where they are being consumed or used.  For a list of the Latin species name associated with the common names listed on the label, refer to the PMRA’s list of Residue Chemistry Crop Groups at

Coragen Insecticide should be used in an integrated pest management program and in rotation with other management strategies to adequately manage resistance. Coragen Insecticide is toxic to aquatic organisms and non-target beneficial insects. Do not contaminate aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. Chlorantraniliprole is persistent and may carryover. It is recommended that any products containing chlorantraniliprole not be used in areas treated with this product during the previous season. The use of this chemical may result in contamination of groundwater particularly in areas where soil is permeable.

Follow all other precautions and directions for use on the Coragen Insecticide label carefully.

We also wish to acknowledge the personnel of the Pest Management Regulatory Agency for evaluating and approving this pest management tool and E. I. DuPont Canada Inc. for supporting these label expansions in Canada.
