The Pesticides Regulatory Directorate (PRD), formerly known as the Pest Management Regulatory Agency (PMRA), recently approved 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.

Follow all other precautions, restrictions, and directions for use on the Allegro 500F agricultural fungicide label carefully.
