Macro-organisms beneficial to plants

Thematic Working Group

The Working Group on "Macro-organisms beneficial to plants" (MACRO WG) reports to the Expert Committee (CES) on "Plant protection substances and products, biocontrol".

With applications for the release into the environment of non-indigenous macro-organisms, the MACRO WG analyses:

  • risks to plant health;
  • environmental risks, in particular for biodiversity;
  • the effectiveness and expected benefits for agriculture.

The MACRO WG also makes recommendations on the conditions for releasing macro-organisms into the environment.
