This book focuses upon the secret agricultural biological warfare programme codenamed Ekologiya – which was pursued by the Soviet Union from 1958 through to the collapse of the USSR in 1991. It was the largest offensive agricultural biowarfare project the world has ever seen and Soviet anti-crop and anti-livestock weapons had the capability to inflict enormous damage on Western agriculture. Beginning in the early 1970s, there was a new focus within the Soviet agricultural biowarfare programme on molecular biology and the development of genetically modified agents. A key characteristic of the Ekologiya project was the creation of mobilization production facilities. These ostensibly civil manufacturing plants incorporated capacity for production of biowarfare agents in wartime emergency. During the 1990s-2000s, the counter-proliferation efforts undertaken by the US and UK played a major role in preventing the transfer of Ekologiya scientists, technologies and pathogens to Iran and other countries of potential proliferation concern.
