This Test Guideline describes a method to estimate the developmental toxicity of a test chemical to the dung dwelling life stages of dung-dependent dipteran species. Two test species can be used. The test chemical is mixed with bovine faeces, to which either 10 eggs of Scathophaga stercoraria or 10 larvae of Musca autumnalis are added. The test will be terminated 5 days after emergence of the last adult in the control (> 18 days for S. stercoraria, >13 days for M. autumnalis). Then the possible impacts of the test chemical on the following measurement endpoints are assessed under controlled conditions: sex and total number of emerged adult flies, retardation of emergence indicated by the developmental rate and morphological change. Depending on the experimental design, the No Observed Effect Concentration (NOEC) or the Effect concentration for x percent effect (ECx) can be determined. This Guideline can be used for water soluble or insoluble substances, but is not applicable to volatile substances. If the toxicity of the chemical is unknown, five nominal test concentrations should be conducted. A positive control should be tested periodically. The test is considered valid if in the controls hatching of larvae is superior or equal to 70% of the number of introduced eggs, emergence of adults is superior or equal to 70% and superior or equal to 50% of the respectively hatched and introduced larvae and if the emergence of adult flies starts after 18 +- 2 days (S. stercoraria) or after 13 +- 2 days(M. autumnalis).

This report presents the results of an OECD seminar on ways to achieve risk reduction while addressing issues associated with the use of chemical pesticides or non-chemical means of crop protection on a small scale.
This document intends to provide a “snapshot” of how OECD countries have developed and run their PRTR programmes. It shows the similarities and differences across countries in their requirements to collect and display high quality data, which is required for an effective PRTR system. It also presents compliance and regulatory requirements, the development of guidance material, and emerging issues and challenges for the future.
This page lists, in chronological order, the Pesticides Publication Series that relate to Minor Uses.
OECD’s Working Party on Manufactured Nanomaterials launched a “sponsorship programme” at its 3rd meeting (November 2007). Countries will share the testing of specific nanomaterials (MNs) under this programme.

This report presents the results of an OECD seminar on ways to achieve pesticide risk reduction through worker safety and training. The seminar was hosted by Czech State Phytosanitary Administration, in Brno, Czech Republic, on 21 March 2007.
This Emission Scenario Document (ESD) is intended to provide information to be used for risk assessment for active substances and products used as biocidal (i.e. non agricultural) insecticides, acaricides and products to control other arthropods (in the EU, product type 18 [PT18] ). Biocidal products marketed as insecticides are used in many different applications. They may be used indoors (within buildings), outdoors (around
OECD’s Working Party on Manufactured Nanomaterials has launched a “sponsorship programme” in which countries will share the testing of specific nanomaterials (MNs) at its 3rd meeting (November 2008). Much valuable information on the safety of MNs can be derived by testing a representative set for human health and environmental safety. In launching this “sponsorship programme” the Working Party agreed a priority list of MNs for
