This document provides additional detailed guidance on rotational crop residue studies conducted according to OECD TG 504: Residues in Rotational Crops with expanded flexibility in crop commodities to be tested, and approaches to mitigate additional testing.

This Overview Guidance Document summarises the major guidance aspects provided in the OECD Guidelines for the Testing of Chemicals, Section 5. This document also develops an approach for a Global Maximum Residue Limit (MRL) process to achieve use of a single globally acceptable feeding study for MRL setting and risk assessment for livestock food commodities that involves four key components: 1) Harmonised Guidance for the Definition of Residue; 2) Reasonable Worst Case Animal Diets/Maximum Reasonably Balanced Diet; 3) Harmonised Table of Livestock Feed Commodities; and 4) Definition of Reasonable Worst Case Livestock Feeding Levels.

This document provides additional detailed guidance on testing of chemicals according to OECD Test Guideline No. 505: Testing of Chemicals on Residues in Livestock. Specifically, it describes current differences in OECD countries in livestock feeding practices and diet composition and factors influencing the determination of dietary burden and dose selection, and provides guidance for interpreting results (including example calculations for dietary burdens and MRL setting) from OECD Test Guideline No. 505 studies.

This document provides guidance on how to conduct terrestrial field dissipation studies to demonstrate the transformation, transport and fate of pesticides under representative actual use conditions when a pesticide product is used according to the label.

This document provides guidance to both industry and regulatory authorities on how procedures and data requirements can be applied to facilitate the submission of a complete data package/dossier for botanical active substances used in plant protection products, and the subsequent evaluation of this data package/dossier by the regulatory authorities.

This report includes the outcomes of the workshop discussions, as well as the overall workshop conclusions (Section 4) and recommendations (Section 5) targeted at governments, all stakeholders and OECD.

The FAO/WHO Manual on development and use of FAO and WHO specifications for pesticides contains general principles and methodologies of the work undertaken by JMPS, is the continuous evaluation of new scientific developments and guidance documents. The Manual gives the historical background of the operation of the JMPS and describes the purpose of the work. The Manual is also used by countries as a guidance document in setting pesticide specifications. This 3rd revision of the Manual contains n ew methodologies/principles developed in recent 5 years and incorporates the current working principles applied by the JMPS.
