Recently PRMA (Pest Management Regulatory Agency) has approved several IMPORTANT minor use label expansions in vegetable production. Minor use label expansions of pest control products are considered on active ingredient(s) currently registered in Canada, which are expanded for additional end uses. Below is a table outlining some of the key information about these products and their end uses (add table directly below this paragraph). Before integrating these products into your current pest management program, please review the label thoroughly and if needed, consult with your favourite agronomist. The Health Canada label search tool has the most accurate and up-to-date labels, and can be found here.
Through the emergency use registration process Ontario, Quebec, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador were successful in obtaining SWITCH®62.5 WG (cyprodinil (group 9) and fludioxonil (group12)) for use has been approved PMRA for the suppression of Alternaria leaf blight (Alternaria brassicicola) on Brussels sprouts, broccoli, and cauliflower. Being an emergency use registration, this use pattern is only permitted from July 8th, 2022, to July 7th, 2023, however a user requested minor use label expansion for this use of SWITCH®62.5 WG has been submitted and will hopefully be approved for the 2023 growing season.
For more information on these products, consult the label or contact your local agronomist.
