Since 1987, James has been a director and manager of Biological Services, commercially producing beneficial organisms for biological pest control programs in horticultural systems, particularly citrus, greenhouse and berry crops(strawberry, raspberry, blueberry).
James was also a founding director of Fruit Doctors Pty Ltd in 1993, providing a wide range of horticultural production advice to growers of citrus, wine/table grapes, almonds, pomefruit, stone fruit and avocados. Regular consultancy was confined to the Riverland/Sunraysia districts, but projects in citrus/wine grapes have been undertaken in all Southern growing districts of Australia.
James is joint owner of Belair Orchards, a 40 hectare fruit property growing several citrus varieties, avocados, wine grapes and some vegetables and greenhouse crops. This property is regularly used to demonstrate sustainable production techniques to clients.
In 1992 he was awarded a Churchill Fellowship to study mass rearing of bio-control agents in USA/Canada, and in 1997 was presented the Les Baker Citrus Industry Award from Australian Citrus Growers Inc., for valuable service and extension advice to citrus growers of Australia.
James is a member of Australian Institute of Agricultural Science and Technology (AIAST) and is accredited as a Certified Practising Agriculturalist (CPAg) by the Australian register of Agricultural consultants since its inception in 1998.
