Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in‐soil organisms

EFSA Journal, Volume 15, Issue 2, February 2017., 2017
Abstract Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in‐soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made
