The Pesticides Regulatory Directorate (PRD), formerly known as the Pest Management Regulatory Agency (PMRA), recently approved an Emergency Use Registration (EUR) request for Pyganic insecticide for management of Nesidiocoris tenuis, “Nesi”, on greenhouse-grown cucumbers and greenhouse-grown tomatoes in Ontario. This EUR request can be used only in Ontario from April 17th, 2026, until April 16th, 2029. The request marks the first agricultural related EUR request to be granted a multi-year term on the grounds of preventing the establishment of a new invasive species.
Pygantic insecticide was already labelled for management of insects on a wide range of crops in Canada. This minor use proposal was submitted by the Ontario Ministry of Agriculture, Food, and Agribusiness and sponsored by the Ontario Fruit and Vegetable Growers’ Association in response to increasing crop damage severity from “Nesi” in recent years. There are currently no other pest control products registered for management of this pest in Canada. Research projects at the most recent National Priority Setting Workshops were elevated for capacity analysis considerations to secure a full label for both uses in the future if selected.
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 label before using Pygantic insecticide.
