MPS-ABC: Reassessment of active substance pelargonic acid/nonanoic acid

Pelargonic acid (also known as nonanoic acid), the active ingredient (component of crop protection agents) in the products in the table below has been reassessed. In the MPS environmental indicator system, active substances are categorised as ‘white’, ‘green’, ‘amber’ and ‘red’. White active substances have the lowest environmental impact. As a result of the reassessment, the categories of some active substances may have changed. This is because new data has become available about the substance(s) concerned. If you use these active substances, their use will influence your number of points.

From period 5 (25 April 2022) onwards, pelargonic acid is changing from ‘white’ to ‘green’.

If you use any of these active substances, their use will influence the number of points in your MPS-ABC score.
