Pesticide Risk Reduction Program Biopesticide Priorities

A number of candidate biopesticides are identified by stakeholders at the annual Biopesticides and Minor Use Priority Setting Workshops held each spring in the National Capital Region. Following the workshop, these candidate products are subject to a merit evaluation and the results of this, together with advice received from provincial and Agriculture and Agri-Food Canada (AAFC) experts are used to determine which 3-4 biopesticide products will receive regulatory support from the Pesticide Risk Reduction Program. The selected biopesticides will also be eligible for inclusion in projects to develop or demonstrate biopesticide use in integrated pest management (IPM) systems.

As a result of this effort the biopesticide products listed below have been selected for Pesticide Risk Reduction Program support.
