Plant Protection Limited moved to this site in 1945 and opened a research institute on the estate of Sir Felix Schuster (1854-1936). The research institute was to investigate pest and disease control, and was also known as a horticultural research station. In June 1951 an international conference, with scientists from 39 countries, took place at the site on food scarcity.[2] On 10 May 1955, the site was visited by the Duke of Edinburgh.
