The Board for the Authorisation of Plant Protection Products and Biocides (Ctgb) decides on authorisation of plant protection products, based on risk assessments. Beside aspects like toxicology and environmental risk, in most cases, also efficacy is assessed.
Through efficacy trials, effectiveness and phytotoxicity aspects are judged. Efficacy assessment is based on an evaluation report written by evaluating bodies. These bodies also give recommendations about the composition of the biological assessment dossier in the process towards actual authorisation.
The Netherlands Plant Protection Service and Linge Agroconsultancy are the evaluating bodies for efficacy in the Netherlands.
