Product Registration Changes in Vegetables!

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 8^th, 2022, to July 7^th, 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.

New pesticide registrations

Agri-Réseau is a resource available through The Centre de référence en agriculture et agroalimentaire du Québec (CRAAQ).  Every month, they publish a list of new phytoprotection registrations.  At Perennia, we are fortunate to have Mélanie Leclerc as part of our staff, and she has translated the March list of new pesticide registrations for Fruit Trees, Field Crops, Vegetables, Greenhouse, Berries, Ornamental, and "Other" (hops, hemp, quinoa, and basil), which can be found here.

From the Vegetable side, the main excitement is a few more weed control options in asparagus, Brassicas, and shallots, and some new disease management options in asparagus, kohlrabi, Brassica leafy greens, and bulb vegetables (Group 3-07A and 3-07B, so bulb onions, garlic, shallots, green onions, leeks, etc.)

Biosecurity is important in horticulture crops too!

Biosecurity, often thought of as a livestock issue, is important in horticulture crops too.  The old adage "an ounce of prevention is worth a pound of cure" is very true for horticulture biosecurity risks, especially since many issues don't have viable solutions.  Equipment can carry soil-borne pests like clubroot, Verticillium wilt, and nematodes from field to field.  The more soil that gets transported between sites, the higher the risk of infection from these soil-borne pests.  Diseases such as downy mildew, late blight, and angular leaf spot can be inadvertently carried on clothes, boots, and gloves.  Difficult to control weeds such as yellow nutsedge can also be carried from field to field on equipment.

Clubroot can be transmitted on equipment, boots, and eroding soil

Important biosecurity management steps are first to make sure that these diseases and pests don't come on to the farm.  If you know you already have problem areas, takes steps to manage and contain them so that it doesn't spread to the rest of your fields.  Manage your culls and plant certified disease-free seeds and root stock.
