The International Pesticide Application Research Consortium (IPARC), previously known as the International Pesticide Application Research Centre and before that the Overseas Spray Machinery Centre (OSMC), has focused on pesticide application methods appropriate for smallholder farmers since 1955. It is now a research and training group whose purpose is to promote practical and cost-effective techniques, wherever possible, reducing the use of chemical pesticides, as part of Integrated Pest Management (IPM). IPARC has been an integral part of pesticide research and teaching at Silwood Park[1] and has specialised in the needs of smallholder farmers, application techniques for migrant pests and control of disease vectors. IPARC is a World Health Organization (WHO) collaborating centre.
