# Updated peer review of the pesticide risk assessment of the active substance dichlorprop‐P and variant dichlorprop‐P‐2‐ethylhexyl

## TL;DR

This paper updates the risk assessment of the pesticide dichlorprop-P and its variant, including their use and residue levels in crops.

## Contribution

The paper provides updated conclusions on the regulatory risk assessment and MRLs for dichlorprop-P and its ester variant.

## Key findings

- Risk assessments were updated for dichlorprop-P and dichlorprop-P-2-ethylhexyl under EU regulations.
- Maximum residue levels were evaluated for mandarin and lemon.
- Endocrine disruption properties and missing regulatory information were identified.

## Abstract

The conclusions of the EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, Ireland and co‐rapporteur Member State, Poland, for the pesticide active substance dichlorprop‐P and the variant dichlorprop‐P‐2‐ethylhexyl and the assessment of applications for maximum residue levels (MRLs) are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached based on the evaluation of the representative uses of dichlorprop‐P as herbicide on cereals, grassland and grass seed crops and of the variant dichlorprop‐P‐2‐ethylhexyl as a plant growth regulator on citrus. MRLs were assessed in mandarin and lemon. The conclusions from 2018 were updated in 2024 following the request from the European Commission regarding the endocrine disruption properties. The conclusions were further updated in 2025 in the context of the peer review required by Regulation (EC) No 1107/2009 of the European Parliament and of the Council for an amendment in approval conditions. The purpose of this application was to extend the existing approval to include the ester variant dichlorprop‐P‐2‐ethylhexyl under Regulation (EC) No 1107/2009 of the European Parliament and of the Council of 21 October 2009 concerning the placing of plant protection products on the market. The reliable end points, appropriate for use in regulatory risk assessment and the proposed MRLs, are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are reported where identified.
