Book excerpt: The fourth edition of this highly regarded book has been considerably enlarged to cover all aspects of cocoa production. Higher prices for cocoa have led to much new knowledge about the plant and changes to its methods of production. These are discussed, along with new problems that have occurred and the fresh research projects that have been needed.

Download or read book Phytophthora written by Kurt Lamour and published by CABI. This book was released on 2013 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book begins with an account of the early history of Phytophthora research and the tumultuous events setting the genus in motion. In keeping with its controversial inception, the chapter on taxonomy and phylogeny makes a compelling case that our current notion of Phytophthora as a genus is illusory. This chapter sets the stage for the importance of molecular tools on these enigmatic pathogens. The following chapters discuss species identification, population-level investigation, interspecific hybrids and the impact of diverse Phytophthora species on crops, forests, nurseries, greenhouses and natural areas worldwide.

Download or read book Cacao Diseases written by Bryan A. Bailey and published by Springer. This book was released on 2016-02-22 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Theobroma Cacao written by Peter Aikpokpodion and published by BoD – Books on Demand. This book was released on 2019-11-06 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost five million tonnes of cocoa produced annually drives the US$100 billion global chocolate industry. To sustain the industry, cacao planting materials (seeds and clones) have been successfully moved from the Amazon forests in America to the humid tropical forests of Africa, Asia, and Australia. In more than 150 years of commercial cacao cultivation, smallholder farmers that supply the bulk of cocoa beans still face several production constraints that impede their efficiency. Scientific technologies have therefore been deployed to remove these constraints by ensuring a continuous supply of good quality cocoa beans to meet growing global demand. This book provides insight into these scientific advances to address these current and emerging problems and to assure the sustainability of the global cocoa industry.
Download or read book Forest Microbiology written by Fred O. Asiegbu and published by Elsevier. This book was released on 2022-07-28 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Microbiology: Tree Diseases and Pests, Volume Three in the Forest Microbiology series, provides an overview of major disease agents of trees, including viruses, phytoplasma, bacteria, fungi, nematodes and major insect pests. With a strong emphasis on genetics, biochemistry, physiology, evolutionary biology and population dynamics of the organisms involved, this book provides a comprehensive understanding on the health of forests. Sections cover important pest threats such as bark beetles, emerald ash borer, coffee borers, leaf cutting ants, cocoa mirids, and more. This volume highlights a range of emerging diseases of forest trees in temperate and tropic regions as well as information on habitats. Forest trees play crucial roles not only for mitigating effects of the climate change but also for their considerable economic and ecological value. Forest trees are equally vital as an alternative bioenergy source and play important roles in pollution abatement and the maintenance of biodiversity. Timber and its associated products from forest trees contribute substantially to the revenue generation of many countries of the world. Includes case studies of complex diseases of economically important trees Highlights novel approaches to managing tree pests and diseases in a changing climate Focuses on the many functions of microbial disease agents of trees Addresses major insect pests of boreal, temperate and tropical trees

This book was released on 2010-03-10 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains fuller versions of the papers and posters presented in the Knowledge and Technology Transfer and Teaching Plant Pathology sessions at the 9th International Congress of Plant Pathology held in Turin, Italy in 2008. Communication is an essential area for plant pathologists and it is not just the publication of results in the scientific press that is important. In a world where there is a major shortage of food and where a significant amount of it is destroyed by pests and diseases before it ever reaches the consumer, it is important to provide support to those who produce the food in order to reduce the losses. Reducing crop losses not only has an impact on health, but also wealth and, therefore, the ability to survive. With an ever-increasing demand on food supplies due to increases in population, and changes in life-style associated with rising incomes in certain parts of the world, plant pathologists have a pivotal role to play in contributing to global food security. Aspects of crop protection have lost favour with the general public because of concerns about environmental pollution and genetic modification of crops. This has had a ‘knock on’ effect in the recruitment and training of crop protectionist in g- eral and a concomitant impact on courses available at universities. However, it has never been more important to train people with good communication skills and an ability to solve problems to tackle the complexities of pathogen and plant interactions.
