Development and validation of methods of analysis for pesticide formulations - PS2547

The Food and Environment Research Agency (Fera) conducts chemical analysis of pesticide formulations for planned surveys on behalf of the Chemicals Regulation Directorate (CRD) of the Health and Safety Executive. Fera also conducts chemical analysis in support of enforcement activities conducted by CRD. To conduct this work analytical methods are required for use in checking the compliance of pesticide formulations on sale in the UK with their registered technical and formulation specifications. These methods are required to determine both the chemical composition (e.g. active ingredient and co-formulant material content) and physical properties (e.g. emulsion stability and suspensibility). This project covers the development and validation of suitable analytical methods.

In some cases, analytical methods will available from the handbooks of the Collaborative International Pesticides Analytical Council (CIPAC) or from pesticide product manufacturers (industry methods). However such methods often need to be validated for use with formulation types, other than those for which they were specified. On occasion methods referenced in Food and Agriculture Organization of the United Nations (FAO) specifications for agricultural pesticides will be available. FAO methods are not collaboratively tested and will therefore require validation. In other cases, it will be necessary to develop and validate new methods by modifying CIPAC methods or industry methods or FAO method. In some cases, it is likely that no suitable CIPAC/industry/FAO methods will be available and in-house methods will be developed and validated.

As part of this project Fera will also participate in collaborative trials organised by ESPAC (English Speaking Pesticides Analytical Council) and CIPAC on proposed new methods of analysis for pesticide formulations. Fera will also take part, where appropriate, in the AAPCO (Association of American Pesticide Control Officials) check sample programme, a multi-laboratory proficiency testing programme for laboratories that analyse pesticide formulations. In addition, Fera will add methods developed for the determination of active ingredients to the Fera/CRD Methods Compendium.
Objective 1
To develop robust analytical methods, that are as cost effective as possible with the available technology, for the analysis of the components of pesticide formulations, including active ingredients, impurities, co-formulants and breakdown products. The methods developed will be utilised for scheduled formulation surveys and enforcement analyses.

Objective 2
Participate in collaborative trials organised by ESPAC and CIPAC, as part of the validation
procedure for proposed new international methods.

Objective 3
Participate in the AAPCO (Association of American Pesticide Control Officials) check sample programme,

Objective 4
Enter methods developed for the determination of active ingredient in the Fera/CRD Methods Compendium
