Low-risk active substances: pesticides

When an active substance is evaluated for approval, if it’s found to present a much lower risk than other active substances, it may be approved as a low-risk active substance.

To be approved as a low-risk active substance, the active substance must satisfy the criteria for approval in Articles 4, 22 and 47 of retained Regulation (EC) 1107/2009.
