His first book, Collins Guide to the Pests, Diseases and Disorders of Garden Plants, written jointly with Dr Keith Harris and illustrated by Brian Hargreaves, has remained the standard reference work for forty years, while his Fauna Britannica was an account of the entire wild animal life of the British Isles for which the then Prince of Wales (now King Charles III) wrote the foreword.
In 2020, Buczacki published his first novel The Marmalade Pot, the story of a young woman's search for her own sexuality, described by Fern Britton as 'intriguing and satisfying'.
Buczacki is married to Beverley, a retired school principal, with whom he has two children: Simon, the Richard Blackwell Pharsalia Professor of Colorectal Surgery at the University of Oxford, and Julian, a Major General in the British Army.
