Josh Mosiondz, provincial minor use coordinator, OMAFRA, is reporting that the Cimegra Insecticide label has been temporarily expanded via Emergency Use Registration to help manage cabbage maggot in broccoli, Brussels sprouts, cabbage, cabbage (Chinese, napa), and cauliflower grown in in Ontario, Alberta, Saskatchewan, Québec, Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador. The use period is from May 17, 2024 until December 31, 2024.

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.

The following is provided as an abbreviated, general outline only. 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 insecticide.

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, OMAFRA, Guelph (226) 971-3407, Hannah Fraser – horticulture entomologist, OMAFRA, Guelph (905) 708-8014, or Travis Cranmer, vegetable crops specialist, OMAFRA, 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
