This book was released on 1997-01 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This booklet describes the background to the Black and Yellow Sigatoka diseases (causal agents Mycosphaerella fijiensis and M. musicola respectively) and the traditional method of diagnosis by fungal isolation. A new, laboratory based molecular biological technique is presented, which gives rapid and sensitive identification of the pathogens, directly from infected banana leaves. The method, developed at NRI, is based on the amplification of fungal DNA by the Polymerase Chain Reaction (PCR). Protocols for DNA extraction and PCR are given, together with details of reagents and their availability. Suitable for use in plant pathology laboratories equipped for basic molecular biology by researchers who require accurate identification to species level for these pathogens of significant economic importance.

Download or read book Phyllosphere Microbial Plant Pathogens Detection and Crop Disease Management written by P. Narayanasamy and published by CRC Press. This book was released on 2024-08-15 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive knowledge of the methods of detection and identification of phyllosphere microbial pathogens and the management of different kinds of diseases caused by them in various crops. Interactions between pathogens and host plants result in the induction of defense responses expressed via molecular signals, from initiation of infection to systemic progression of pathogen invasion in susceptible plants and contrasting signals in resistant plants, leading to inhibition of pathogen development through activation of preinfectional and postinfectional defense responses. These are critically discussed. The author describes the intricate and complex competitive activities of the pathogens and host plants in a molecular warfare that the host plant must win to break the link in the pathogens' life cycle, allowing the development of disease management strategies based on the principles of exclusion, eradication, and immunization. Integration of strategies concerning the development of cultivars resistant to pathogens through breeding and biotechnological techniques, application of biotic and abiotic inducers of resistance to pathogens, and use of disease-free seeds and propagules that are complementary to each other along with effective cultural practices are emphasized. This book presents information gathered through an extensive literature search to help researchers and graduate students in agricultural sciences identify research gaps and successfully complete their research projects.

Download or read book Pathogen Indexing Technologies written by and published by Elsevier. This book was released on 1996-06-21 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant advancements have been made in pathogen detection technologies during the last decade. Indexing of plants and plant parts for the presence of specific pathogens has been most effective in some instances for avoiding and/or controlling disease. The new technologies for detecting low levels of pathogens will increase the value of indexing as a tool for plant disease control. Providing an overview of the status of detection technology, this volume is directed not only to scientists and students interested in detection technology, but also to those interested in formulating and implementing disease control and quarantine regulations. This book provides a conceptual framework which presents the current scientific literature, state-of-the-art assessments, and speculations on future developments and requirements of pathogen indexing methods. Chapters cover the different pathogen groups, review current practices in areas where detection technology has become important, and provide perspectives on how indexing technologies can be applied, how well it has worked, and which problems remain. Statistical treatment of detection limits, sampling strategies, risk assessment, cost, standardization, and quality control are also covered.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
