Adjuvants include antifoams, bonding agents, synergists, safeners and other substances which are placed on the market to improve the action of plant protection products. The co-formulants of plant protection products do not fall under adjuvants based on this definition.

In accordance with article 1 of the Royal Decree of 28 February 1994 adjuvants are treated as a plant protection product.

Authorisation of an adjuvant

Like plant protection products, adjuvants are assessed by the Authorisation Committee. The application dossier is submitted with a draft Registration Report and the assessment is made in accordance with the Belgian national requirements. A guide containing the requirements has been drawn up to help applicants prepare their dossiers.
