Bernard J. Blum (1 September 1938 in Besançon – 13 August 2014 in Paris) was a French agricultural scientist, industry manager and founding president of the International Biocontrol Manufacturers' Association (IBMA).
It was as regional manager in Africa that he began to use decision-making systems, i.e. the technical possibilities for reducing the use of plant protection agents in cotton crops.
At the beginning of the 1990s he founded, together with colleagues, the Académie du Biocontrôle et de la Protection Biologique Intégrée in France.
He promoted a return to the consideration of Bio-diversity and an integrated plant protection policy grounded on an analytical system and preventative measures.
Inter alia he began, together with the makers of meteorological monitoring stations, the development of crop-specific computer programmes which would give an early warning of risk situations – attack by insects or disease – to allow more targeted intervention using less, and also alternative, agents.
