Allegro® 500F Agricultural Fungicide label expanded via Emergency Use Registration to suppress Neopestalotiopsis leaf blight and fruit rot on field strawberries in Ontario, British Columbia, Alberta, Quebec, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador
The Pesticides Regulatory Directorate (PRD), formerly known as the Pest Management Regulatory Agency (PMRA),recently announced the approval of an Emergency Use Registration request effective June 2, 2026, until June 1, 2029 for suppression of Neopestalotiopsis leaf blight and fruit rot on field grown strawberries in all provinces of Canada (Ontario, British Columbia, Alberta, Quebec, Saskatchewan, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador).
Allegro® 500F Agricultural Fungicide was already labeled for disease control on a wide range of crops in Canada. This Emergency Use Registration request was submitted by the Ontario Ministry of Agriculture, Food, and Agribusiness as a result of minor use priorities established by growers and extension personnel and the urgent need for a management product for this newer disease. A temporary MRL of up to 3.5 ppm has been established on strawberries in Canada, however, any growers exporting fruit out of country should ensure a tolerance is established in the destination country before considering applications in their production systems.
The following is provided as an abbreviated, general outline only. Users should be making disease management decisions within a robust integrated disease management program and should consult the complete label before using Allegro® 500F Agricultural Fungicide.
Environmental Precautions: Toxic to aquatic organisms and non-target terrestrial plants. Observe spray buffer zones specified under DIRECTIONS FOR USE. Toxic to small wild mammals. The residues of fluazinam are persistent and may carry over. It is recommended that this product not be used in areas treated with any products containing fluazinam during the previous year. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative filter strip between the treated area and the edge of the water body. Additional guidance can be found on the Runoff Mitigation portion of the Canada.ca website.
Follow all other precautions, restrictions, and directions for use on the Allegro® 500F Agricultural Fungicide label carefully.
