Environmental stewardship of plants with novel traits in Canada

The environmental stewardship of the following plants includes planning and managing their use to reduce resistance development and to protect the environment:

  • herbicide tolerant plants
  • insect resistant plants
  • disease resistant plants

This responsible management is a joint effort by:

  • growers
  • product developers
  • academia
  • regulatory bodies

Environmental stewardship can involve:

  • sharing and applying best management practices through national and local programs
  • working with provincial and academic experts
  • implementing product‑specific stewardship plans

The Canadian Food Inspection Agency may require environmental stewardship plans for plants with novel traits (PNTs) as a tool to manage potential risk to the environment.

Environmental stewardship for different types of plants

Plant type Goal Approach
Herbicide tolerant
  • delay the development of herbicide resistant weeds
  • mitigate gene flow to weedy relatives
  • control herbicide tolerant volunteers

Integrated weed management principles

  • cultural (for example, crop rotation)
  • chemical (for example, herbicide rotation)
  • mechanical (for example, tillage)
  • regular field checks and reporting issues
Insect resistant
  • delay the development of insect resistance

Integrated pest management principles

  • cultural (for example, crop rotation)
  • biological (for example, introducing natural enemies)
  • chemical (for example, insecticide rotation)
  • mechanical (for example, trapping)
  • regular field checks and reporting issues
Disease resistant
  • delay the development of pathogen resistance

Integrated disease management principles

  • cultural (for example, crop rotation)
  • biological (for example, introducing natural enemies)
  • chemical (for example, fungicide rotation)
  • regular field checks and reporting issues

Additional information on environmental stewardship

There is a variety of information available to help growers determine the best stewardship measures to implement.

Plants with novel traits authorized with stewardship conditions

Not all plants with improved characteristics are considered plants with novel traits (PNTs). Find guidance on determining the novelty of a plant, the types of environmental release and application process for PNTs in Canada:

Applying for environmental release of plants with novel traits in Canada

In some cases, PNTs may be authorized with conditions to implement stewardship measures to manage potential environmental risks. Once a PNT is authorized for release, stewardship obligations continue throughout the life of the product, even after its patent has expired.
