The fungus Fusarium oxysporum f.sp.cubense (Foc) causes Fusarium wilt,in the banana industry commonly referred to as Panama disease.This disease is currenly considered as one of the most destructve diseases in certain banana growing areas of the world.False Panama disorder,which can easily be confused with Fusarium wilt,was first described by Deacon et al.in 1985.
Annotation. Comprehensive information on diseases of the most important tropical fruit cropsChapters are devoted to a single or, in some cases, a related group of host plantsThe history, distribution, importance, symptoms, aetiology, epidemiology and management of diseases of each crop are described in detailThis book offers a comprehensive review of diseases of important tropical and some subtropical fruit crops. The history, distribution, importance, etiology, epidemiology and control of diseases of each host crop are covered, along with brief summaries on the taxonomy, origins and characteristics of each host. Additional information is given on the biology and pathology of the causal agents and on new advances that change or otherwise enhance our understanding of the nature and cause of these diseases. Plant pathologists, plantation and nursery managers, lecturers and those who are involved in tropical agriculture and horticulture will find this an essential reference.

This book provides a comprehensive guide to the large number of diseases, disorders and injuries that can cause severe economic losses to banana, abacá and enset crops, and the fungi, bacteria, phytoplasmas, viruses, nematodes and abiotic factors involved. The monoculture of certain banana cultivars in large plantations make the crop particularly susceptible to catastrophic losses from disease and smallholders can also experience major problems. New approaches to breeding, crop management and handling are being developed to meet challenges posed by emerging threats. Handbook of Diseases of Banana, Abacá and Enset both describes and illustrates diseases and is printed in full colour throughout, creating a valuable diagnostic tool. It covers: - The origin and classification of banana, the safe movement of Musa germplasm and banana breeding for disease resistance. - Recent areas of growing research on the most important diseases of banana, such as black leaf streak, Fusarium wilt, Xanthomonas bacterial wilt and bunchy top. - Significant advances relating to pathogens causing less serious and widespread diseases. Authored by an international team of experts, this is an essential reference for all 'banana doctors' around the world. It serves as a useful field and laboratory guide, as well as a source of information for all those investigating diseases of banana, abacá and enset crops.

This book presents an important contribution to the knowledge of the banana soils of Venezuela. Banana, the edible fruit of Musaceae, is a staple food for more than 400 million people worldwide due to their nutritional and energy attributes. This makes Musaceae a crop of worldwide relevance, particularly in tropical regions, highlighting the impact of improved Musaceae cropping systems in the current efforts worldwide oriented towards a new agricultural revolution based on sustainable intensification. To achieve this, better practices for food production based on scientific and technical research capable to consider the complexity and variability within the agri-food sector are necessary. The research presented in this book is oriented towards providing answers to the causes of two aspects considered of high relevance for banana production, both affecting productivity and sustainability, always addressed for the Venezuelan conditions, one of the world’s largest producing countries: 1- The impact of phytosanitary risks related to Fusarium Wilt (FW) and the influence of the soil on the incidence of Banana Wilt (BW); and 2- An observed trend towards loss of productivity and decline of soil quality in some commercial farms of Aragua and Trujillo states in Venezuela. The book presents a pioneering study in the application of categorical regression (CATREG) in the characterization of banana soils and analyses soil morphological variables, such as texture, dry consistency, biological activity, reaction to HCl, and type of structure to characterize soil productivity for growing healthy bananas. It develops, for the first time in Venezuela, risk analysis and climatic suitability maps for lethal wilt disease in bananas caused by Fusarium oxysporum f. sp. cubense (Foc) Tropical Race 4 (TR4) (syn. Fusarium odoratissimum). Innovative machine learning techniques are used to predict BW so that future crop development can be done more efficiently and sustainably.
The bananas we eat today aren't your parents' bananas: We eat a recognizable, consistent breakfast fruit that was standardized in the 1960s from dozens into one basic banana. But because of that, the banana we love is dangerously susceptible to a pathogen that might wipe them out. That's the story of our food today: Modern science has brought us produce in perpetual abundance once-rare fruits are seemingly never out of season, and we breed and clone the hardiest, best-tasting varieties of the crops we rely on most. As a result, a smaller proportion of people on earth go hungry today than at any other moment in the last thousand years, and the streamlining of our food supply guarantees that the food we buy, from bananas to coffee to wheat, tastes the same every single time. Our corporate food system has nearly perfected the process of turning sunlight, water and nutrients into food. But our crops themselves remain susceptible to the nature's fury. And nature always wins. Authoritative, urgent, and filled with fascinating heroes and villains from around the world, Never Out of Season is the story of the crops we depend on most and the scientists racing to preserve the diversity of life, in order to save our food supply, and us.
The guidelines are divided into two parts. The first part makes general recommendations on how best to move Musa germplasm. The second part covers the important pests and diseases of quarantine concern. The information given on a particular pest or disease is not exhaustive but concentrates on those aspects that are most relevant to quarantine.
