In our fields, several plant protection products (PPPs) are often applied at the same time and/or in sequence. In the current authorisation, however, PPPs are only evaluated individually. As a result, effects from typical PPP applications often remain undetected and represent a problematic and alarming gap in the authorisation of PPPs.

The authors of the present study evaluated almost 900 PPP spray series applied in 12 different main crops. The result: The overall risk of PPP applications is underestimated
