The Pest Management Regulatory Agency (PMRA) has approved an Emergency Use Registration (EUR) for Cimegrainsecticide for management of cabbage maggot on broccoli, Brussels sprouts, cabbage, cabbage (Chinese, napa), and cauliflower in numerous provinces in Canada. This EUR can be used only in Ontario, British Columbia, Alberta, Québec, Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador from March 1st, 2025 until December 31st, 2025.

Cimegra insecticide is labeled for management of insects on a wide range of crops in Canada. Plans are underway to submit provincial User Requested Minor Use Label Expansion (URMULE) request with the hope for full registration on these crops in future field seasons. These EUR requests were initiated by participating provinces in response to the loss of chlorpyrifos applications in Canada following RVD2020-14 and the subsequent re-evaluation note REV2021-04 which created a lack of sufficient registered protective products to allow for effective protection from cabbage maggot on several crops in Canada, including those in this request. This EUR was led by Saskatchewan in conjunction with other participating province’s provincial Ministries of Agriculture and their local growers’ associations.

Users should be making insect management decisions within a robust integrated insect management program and should consult the complete emergency use label before using Cimegra.

NOTE: The use of Cimegra on broccoli, Brussels sprouts, cabbage, cabbage (Chinese, napa), and cauliflower is intended only for domestic markets due to a lack of export MRLs being established in other trading partner countries. If exported, detection of residues on these crops could lead to rejection or destruction by the appropriate officials.

For a copy of the emergency use label, Ontario growers may contact Josh Mosiondz, provincial minor use coordinator, OMAFA, Guelph (226) 971-3407, Hannah Fraser – horticulture entomologist, OMAFA, Guelph (905) 708-8014, or Travis Cranmer, vegetable crop specialist, OMAFA, Guelph (519) 835-3382. Non-Ontario growers from participating provinces may contact their local provincial minor use coordinator or provincial crop specialist(s).  Alternatively, you may contact your regional supply outlet, BASF Canada (Cimegra) representative, or visit the PMRA label site
