Microbial Plant Pathogens and Crop Disease Management by P. Narayanasamy Download PDF EPUB FB2

Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens.

Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens.

The book presents strategies for the management of crop diseases, and explores means of integrating various strategies to achieve desired levels of suppression.

It describes methods of preventing introduction of microbial pathogens, cultural practices that suppress pathogen populations, alternative soil treatments, resistant cultivars, biocontrol agents, biotechnology for improvement of disease resistance, and crop disease management.

The book presents strategies for the management of crop diseases, and explores means of integrating various strategies to achieve desired levels of by: This chapter discusses the genetic component involving identification of sources of resistance to disease(s), and the utilization of selected sources of resistance in breeding programs to develop cultivars with resistance to seed‐ and propagule‐transmitted diseases of various crops caused by microbial pathogens.

Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum.

Controlling the threat of fungal pathogens. The most common crop diseases are spread by fungi on leaf surfaces and environmental elements like the wind and rain help spread the fungal spores to nearby plants, posing a serious threat to a farmer’s crop.

These fungal pathogens are responsible for crop losses of up to 30% worldwide. 1. Introduction. It is a persistent issue worldwide that an enormous number of plant pathogens, varying from the smallest viroid consisting solely of a single strand of RNA, to more complex pathogens such as viruses, bacteria, fungi, oomycetes and nematodes, cause many important plant diseases and are responsible for major crop losses.

Hence, this book intends to present to the reader all the latest material and knowledge about plant pathogens, changes or refinements in plant disease epidemiology, and new approaches and materials used for plant pathogen control.

Hopefully, this book will be of interest to those working within the field and looking for an up-to-date introduction. They are called plant pathogens when they infect plants.

For the purposes of discussing plant pathology, only plant disease pathogens will be discussed. Pathogens can spread from plant to plant and may infect all types of plant tissue including leaves, shoots, stems, crowns, roots, tubers, fruit, seeds and vascular tissues (Figure 62).

Figure   A symptom of plant disease is a visible effect of disease on the plant. Symptoms may include a detectable change in color, shape or function of the plant as it responds to the pathogen. Leaf wilting is a typical symptom of verticilium wilt, caused by the fungal plant pathogens Verticillium albo-atrum and V.

dahliae. Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. Plant diseases can be classified as infectious or noninfectious, depending on the causative agent.

Learn more about the importance, transmission, diagnosis, and control of plant diseases. Nanotechnology can specifically target specific phytopathology problems in agriculture such as in plant–pathogen interactions and provide new methods for crop disease management.

Different agricultural practices, such as the use of crop rotation, cover crops, disease resistant varieties, and good seed bed preparation have been applied to control pests and diseases.

However, such practices are not always sufficient protection from crop losses. Because of this, many certified organic growers turn to biopesticides to insure and/or enhance their abilities to. Bacterial plant diseases represent a major limitation to crop production and contribute to significant economic losses annually.

Copper compounds and antibiotics have been successfully employed as management strategies in fields since the early s (Elguindi et al., ; Zaumeyer, ). Introduction. Many general characteristics of plant bacterial diseases (examples shown in Fig.

1) favour disease incidence, pathogen dissemination and pathogen survival, and confound management strategies in agricultural es of these include: (i) the growth rate of bacterial pathogens under optimal environmental conditions can quickly result.

Disease prevalence under warm weather causing upto % yield loss. Xcm infected plant show symptoms on seeds, stems, bolls and leaves at any stage of the growth by invading through wounds or stomata. The survival time of pathogen is about 22 months in seeds and can also live in crop debris throughout winter.

Disease management remains limited and is hampered by the faculty of the pathogen to survive for years in wet soil, water ponds, on plant debris or in asymptomatic weed hosts, which act as inoculum reservoirs. one of the most serious plant diseases affecting various crop species worldwide.

With Dr. Vidhyasekaran’s keen insights and experienced critical viewpoint, Bacterial Disease Resistance in Plants: Molecular Biology and Biotechnological Applications not only. Antimicrobial Resistance in Plant Pathogens. Antimicrobial resistance in plant pathogenic target bacteria began to appear as early as the s, a few years after introduction of use of streptomycin [15, 17].Resistance has also been found to be linked with copper resistance [16, 18].Genetically, resistance genes may be chromosomal or carried on plasmids or transposons.

Endophytes: an emerging microbial tool for plant disease management. Inde Barry first used the term 'endophyte' to define bacteria or fungi that occur within asymptomatic plant tissues. Endophytes include bacteria, fungi and actinomycetes.

Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic included.

Plant disease epidemiology is the study of disease in plant populations. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants.

Plant disease epidemiologists strive for an understanding of the cause and effects of disease and develop. Powdery mildew and downy mildew are two devastating diseases on cucumber and other cucurbit crops caused by Podosphaera xanthii and Pseudoperonospora cubensis, respectively.

Identification and detection of these pathogens from field and plant material could be significant for the selection of resistant varieties and formulation of disease management strategies.Biocontrol of Plant Diseases by Bacillus subtilis, Makoto Shoda Books, CRC Press Books, at Meripustak.This book provides a comprehensive account of interaction of host and its pathogens, induced host resistance, development of biological control agents for practical applications, the underlying mechanism and signal transduction.

The book is useful to all those working in academia or industry related to crop protection.
