The routine use of pesticide tank mixtures has increased the importance of formulation tank mix compatibility. Unfortunately, compatibility is very sensitive to the mixing and spraying conditions. Consequently, incompatibility occurs erratically in the field and is difficult to consistently reproduce in the laboratory. While compatibility in the field can never be totally predicted in the laboratory, the test method used in this work provides good predictions, while still allowing the testing of many combinations of pesticides and carriers with a reasonable effort.

In light of an established need for more efficient analytical procedures, this publication, which documents the findings of an IAEA coordinated research project (CRP) on Quality Control of Pesticide Products, simplifies the existing protocol for pesticide analysis while simultaneously upholding existing standards of quality. Based on peer reviewed and internationally recognized methods published by the Association of Analytical Communities (AOAC) and the Collaborative International Pesticides Analytical Council (CIPAC), this report provides laboratories with versatile tools to enhance the analysis of pesticide chemicals and to extend the scope of available analytical repertoires. Such knowledge will prove particularly useful for developing countries. Adoption of the proposed analytical methodologies promises to reduce laboratories use of solvents and the time spent on reconfiguration and set-up of analytical equipment. This publication includes both a report on the development work

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.
