Pesticides have played a critical but sometimes controversial role in the development of agriculture. This book provides an authoritative account of the development of the modern pesticides industry. It discusses the emergence of major pesticide companies such as Bayer, Monsanto, Rhone Poulenc, Dow, DuPont, Ciba-Geigy, Syngenta, BASF and ICI. It covers their competitive strategies such as product development, mergers/acquisitions and diversification. Individual company strategies are placed in the context of broader developments in agriculture which have driven the evolution of the industry, from the Pre-Productionist period to the contemporary world of Post-Productivism and the Sustainability Paradigm. It also reviews how companies have responded to changing national and international policy towards the role of pesticides in agriculture and efforts to regulate their use.
