Formerly known as the International Pesticide Application Research Centre, IPARC has focused on application methods for smallholder farmers. We emphasise practical and cost-effective techniques to manage pests, while reducing the use of chemical pesticides and promoting the efficacy of natural processes and alternative biological agents. Based in Berkshire, England, IPARC has been an integral part of pesticide research at Silwood Park for more than 60 years. It has specialised in the needs of small-holder farmers, application techniques for migrant pest and vector control.
IPARC is a World Health Organisation (WHO) collaborating centre, and its activities have been endorsed by the Pesticide Evaluation Scheme (WHOPES). IPARC has been awarded the BEST PESTICIDE RESEARCH & EDUCATION AGENCY – Europe 2017 by the Industry Insight Monthly journal
Applying less pesticide …
… more safely …

The centre is equipped to carry out research, evaluation and training on the application of both chemical and biological pesticides. Staff often carry out consultancy work for international organisations and commercial companies, as part of IC Consultants. Core expertise includes:
IPARC scientists are involved in improvement of application methods for tree crops such as cocoa. Our extensive data base of application equipment, spray nozzles and ancillary equipment (such as the pressure regulating valve shown here) has proved very useful for this work.
Research is followed-on by training: we produce, or have participated in the development of, a number of guides, books and other training materials, such as the 10-point guide to spraying cocoa.
IPARC scientists have consistently promoted pest control that has minimal impact on the environment. A substantial amount of biopesticide development has been carried out here, including formulation and application development of ‘Green Muscle’ for the LUBILOSA Programme. This product is based on the fungus Metarhizium anisopliae var. acridum, which effectively controls locusts without affecting their natural enemies. In collaboration with ACIS R&D, we are currently carrying out further development of the ‘Mycoharvester’: a device for extracting pure spores of beneficial fungi such as Beauveria, Metarhizium and Trichoderma spp.
IPARC participates in various initiatives for developing and promoting a wide range of biological pesticides, including: COST-850 and SIP. Current lines of research include:
IPARC was involved in a number of research projects related to the ‘Electrodyn’ sprayer. Unfortunately due to commercial factors, the use of this highly innovative system is now limited to insecticide applications on tree saplings.
A project has been carried out in IPARC to design and develop alternative application systems for protecting saplings of Sitka spruce and Scots pine, using conventional pesticide formulations. This system may reduce the risk of operator contamination, both during actual application and when refilling or cleaning the system. The system must also be safe to use, complying with all health and safety regulations. Another requirement is that the volume of waste pesticide solution is kept to a minimum, to reduce disposal costs and risk of environmental contamination.

|Pesticide Application Methods, is the standard textbook on this subject and now in its fourth edition; it was written using the extensive field and laboratory experience gained in association with IPARC and its collaborators. The chapters describe:
1. Chemical control in integrated pest management
2. Targets for pesticide deposition
3. Formulation of pesticides
4. Spray droplets
5. Hydraulic nozzles
6. Manually carried hydraulic sprayers
7. Power-operated hydraulic sprayers
8. Air-assisted sprayers
9. Controlled droplet application
10. Electrostatically charged sprays
11. Aerial application
12. Spray drift
13. Seed treatment, dust and granule application
14. Space treatment by fogging
15. Specialist application techniques (Injection, fumigation and other techniques)
16. Application of bio-pesticides
17. Maintenance of equipment
18. Safety Precautions
19. Equipment for laboratory and field trials
20. Selection of spraying equipment for chemical and biological pesticides
As a Centre, maintained a capacity to carry out research evaluation and development, of whole sprayers, nozzles and active formulations. Many of these facilities will shortly be moved to Harper Adams University, including:
