Book Description
The Monograph deals with the conception, planning, implementation, results and conclusions of the International Witches' Broom Project (IWBP), which was set up in 1985 with the aim of producing an economic management system for witches' broom disease of cocoa. The contributions of the various sponsors, and the roles played by the participating organizations and scientists are described in the introductory chapter. Chapter 2 provides a review of what was, and what was not known from published literature about the cocoa witches' broom pathosystem in 1989. The scope of the project and the approaches used are covered in Chapter 3, while Chapters 4 to 13 report on the field studies themselves in detail. The recent appearance of witches' broom in the important cocoa area of Bahia in Brazil is described in Chapter 14, before disease management recommendations are summarised and future prospects considered in the closing chapters. The many man-years of field research in the IWBP in a total of six countries generated much useful information which was analyzed both in the individual countries and collectively. Even with a document of this size, certain information and analyses with less direct relevance to disease management had to be omitted. It is expected that more detailed treatments of certain aspects will emerge in scientific papers, and further analyses will be undertaken.

Book Description
The process of nation-building in Latin America transformed the relations between the state, the economy, and nature. Between 1760 and 1940, the economies of most countries in the Spanish Caribbean came to depend heavily on the export of plant products, such as coffee, tobacco, and sugar. After the mid-nineteenth century, this model of export-led economic growth also became a central tenet of liberal projects of nation-building. As international competition grew and commodity prices fell over this period, Latin American growers strove to remain competitive by increasing agricultural production. By the turn of the twentieth century, their pursuit of export-led growth had generated severe environmental problems, including soil exhaustion, erosion, and epidemic outbreaks of crop diseases and pests. This book traces the history of the intersections between nature, economy, and nation in the Spanish Caribbean through a history of the agricultural and botanical sciences. Growers and governments in Venezuela, Puerto Rico, Cuba, Colombia, and Costa Rica turned to scientists to help them establish practical and ideological control over nature. They hoped to use science to alleviate the pressing environmental and economic stresses, without having to give up their commitment to export-led growth. Starting from an overview of the relationship among science, nature, and development throughout the export boom of 1760 to 1930, Stuart McCook examines such topics as the relationship between scientific plant surveys and nation-building, the development of a "creole science" to address the problems of tropical agriculture, the ecological rationalization of the sugar industry, and the growth of technocratic ideologies of science and progress. He concludes with a look at how the Great Depression of the 1930s changed the paradigms of economic and political development and the role of science and nature in these paradigms.

Book Description
This book reviews the current state of knowledge concerning cacao pathogens and methods for their management. Topics discussed include the history, biology and genetic diversity of Moniliophthora species (which cause witches’ broom and frosty pod rot) and Phytophthora species (which cause black pod rot) that cause diseases resulting in major losses to cacao production. Emerging pathogens such as Cacao swollen shoot virus and Ceratobasidium theobromae (which causes vascular streak dieback) are also discussed in detail, along with many pathogens of significant local concern. Most of these pathogens represent major risks to global cacao production should they expand into new areas, breaking out of their current limited distributions. By considering cacao diseases as a group, similarities in the available tools and techniques used in their management become apparent, as do their limitations. Gaps in our current knowledge of cacao pathogens and the management of the diseases they cause are detailed, and suggestions for future research directions are provided. This insight allows readers to consider cacao disease threats from a more comprehensive, global perspective and paves the way for an improved synergy of efforts between the various research programs, agencies, and industries, both private and public, with vested interests in cacao production, and cacao farmers.
