Roy Bateman


Principal areas of expertise

  • Dr. R.P. Bateman has specialised in pesticide application for over 25 years, having carried out extensive crop protection work in Asia, Africa and the Americas. He has a particular interest in Controlled Droplet Application techniques and has first hand experience of locust control and pest management of apples, cocoa, cotton, coconuts, maize, sugar cane, rice and vegetables. The overall aim of his work is the alleviation of the more deleterious aspects of using pesticides by improving the specificity, efficiency and timing of their application (rational pesticide use strategies).

  • Authority on the application of biopesticides. For twelve years he was the formulation and application specialist for LUBILOSA Programme: international, collaborative (between CABI Bioscience, IITA, CILSS and GTZ) research dedicated to the biological control of locusts and grasshoppers using the fungus pathogen Metarhizum anisopliae.

  • Chairman of the British Crop Protection Council Expert Working Group on Application Methods and session organiser for New Insecticides section of the Brighton Conference. Academic Visitor, Imperial College, University of London; editorial board member, Pest Management Science.


  • 2003 - Present: Research & Development Manager, International Pesticide Application Research Centre (IPARC), Silwood Park, Acot, UK. Current research: RPU techniques for cocoa disease control in Latin America (USDA sponsored).
  • 1989 - 2003: CABI Bioscience (previously International Institute for Biological Control). Mostly as biopesticides fromulation and application specialist for the LUBILOSA Programme. Developed oil-based formulations of 'Green Muscle'; named, carried aout laboratory and field testing; prepared toxicology and other registration documents for the product. Subsequently developed the 'myco-harvester' (with collaborators) a device for improved mycopesticide spore separation. Other projects include: biopesticide training, project development activities and water hyacinth control.
  • 1985 - 1989: UK, Zimbabwe, Malawi (Industry sponsored Ph.D. project followed by consultancy for further field evaluation of thiodicarb (a carbamate insecticide).
  • 1981 - 1985: Viet Nam (FAO) - Consultant/ technical adviser with various crop protection projects, including management of large supply programme (total US$10 million). Also worked on pesticide field trials, extension and assisted with setting up of a pesticide quality control laboratory run by the Plant Protection Department.
  • 1976 - 1979: Philippines (VSO) - Teaching Entomology at Xavier University agricultural Complex, Cagayan de Oro (included extension work on rice, maize and coconuts).


  • University of Manchester, B.Sc.(Hons) Zoology, (1971 - 1974)
  • University of London, Imperial College, M.Sc. in Applied Entomology (tropical & temperate), (1979 - 1980)
  • Ph.D., University of London, Imperial College. Thesis:
    "Controlled Droplet Application of Particulate Suspensions of a Carbamate Insecticide." (1985 - 1989)
