The FAO minimum requirements in this publication are based on existing international, European and national standards and other published references. The guidelines provide a practical aid to assist purchasing and other agencies to avoid buying or approving sprayers with quality and design limitations, which could compromise operator and environmental safety. Member countries should adopt them immediately, to begin to eliminate substandard and unsafe sprayers from national markets and ultimately from the international scene.

These guidelines have been prepared to offer practical help and guidance to all those involved in using pesticides for food and fibre production as well as in Public Health programmes. The guidelines in this document cover the application of pesticides using aircraft, including the activities on the ground in support of the aerial application .

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.

Pesticides continue to provide an important tool in integrated pest management (IPM) programmes. Hitherto IPM programmes have had a strong bias towards insect control, but farmers need to control weeds, plant pathogens and other pest problems.This book follows the author's successful “pesticide application methods” by relating the equipment needs to the overall pest control requirement of major crops. It outlines the pest problems against which farmers are using pesticides and focusses on the details of the application techniques they need to optimise pesticide use.Much attention is now being given to genetically modified crops, but these do not necessarily avoid the use of pesticides. Some are engineered to be resistant to certain herbicides, so the use of these herbicides will still require careful application in order to minimise environmental side effects. Similarly, crops engineered for resistance to certain insect pest species may remain susceptible to other pests, thus emphasising the need for crop monitoring and careful use of any chemicals to avoid disrupting biological control.

This publication contains revised FAO minimum requirements for safety and quality standards for agricultural pesticide sprayers, based on existing international, European and national standards and other published references. These guidelines seek to assist the elimination of substandard and unsafe sprayers from national markets and ultimately from the international scene.

The guidelines in this document are addressing government officials in plant protection, environmental and other concerned authorities. They consider the training, testing and certification of those who actually operate pesticide application equipment. Even the most well-designed and maintained applicators can do immeasurable damage in the hands of an unskilled operator and the importance of this guideline should not be under-estimated.
