Download or read book Current Trends in Plant Disease Diagnostics and Management Practices written by Pradeep Kumar and published by Springer. This book was released on 2016-04-28 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.

Download or read book Electron Microscopy of Plant Pathogens written by Kurt Mendgen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants, fungi, and viruses were among the first biological objects studied with an electron microscope. One of the two first instruments built by Siemens was used by Helmut Ruska, a brother of Ernst Ruska, the pioneer in constructing electron microscopes. H. Ruska published numerous papers on different biological objects in 1939. In one of these, the pictures by G. A. Kausche, E. Pfankuch, and H. Ruska of tobacco mosaic virus opened a new age in microscopy. The main problem was then as it still is today, to obtain an appropriate preparation of the specimen for observation in the electron microscope. Beam damage and specimen thickness were the first obstacles to be met. L. Marton in Brussels not only built his own instrument, but also made considerable progress in specimen preparation by introducing the impregnation of samples with heavy metals to obtain useful contrast. His pictures of the bird nest orchid root impregnated with osmium were revolutionary when published in 1934. It is not the place here to recall the different techniques which were developed in the subsequent years to attain the modern knowledge on the fine structure of plant cells and of different plant pathogens. The tremendous progress obtained with tobacco mosaic virus is reflected in the chapter by M. Wurtz on the fine structure of viruses in this Volume. New cytochemical and immunological techniques considerably surpass the morphological information obtained from the pathogens, especially at the host-parasite interface.

Download or read book Sheath Rot Disease of Rice written by K. Manibhushan Rao and published by Daya Books. This book was released on 1996 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheath rot (ShR) has been known almost for a century, but was restricted to South East Asia and the Indian Subcontinent. Occurrence of the disease became widespread in mid 1970s when the high yielding technology was introduced by planting improved N-responsive cultivars. Today, ShR is a major constraint in rice production in irrigated as well as rainfed, upland rice. The disease has been reported in many rice growing countries and its spread causes concern because of its transmission and dissemination. The causal fungi, Sarocladium spp, have biological association with rice tungro virus, mites, stem-borers and mealy bugs and therefore increases the ShR incidence as well as severe yield losses. Scant information is available on the biology of the causal organism both in vitro and in vivo. Although a few tall cvs have been identified as resistant, almost all the high-yielding, improved cvs are susceptible to ShR. Biology of the ShR pathogens, host range, varietal resistance and future perspectives were discussed and the importance for a holistic approach to disease control was emphasized.
