Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases are among the important factors that are responsible for causing yield loss in crop production. The loss due to diseases alone is estimated to be around 26 per cent. Diseases may attack at any stage of the standing crop, from seedlings till maturity of the crop. They may affect different parts of the plants, such as foliage, stem, root, flowers or seed and cause various types of symptoms, while the diseases such as wilt affect the entire plant. All these ultimately result in the reduction of yield and poor quality of the produce. Further, many pathogens continue to attack the stored grains and stored produce, and cause spoilage. To save the crops from diseases caused by pathogens and thereby to increase crop production, it is imminent that diseases have to be controlled by any means. To adopt various strategies for the control of pathogens, one should have some basic knowledge about the symptoms produced by the pathogens, their life cycle, mode of survival and spread, and the stage at which the host is most vulnerable to attack by the pathogens. Most of the cultivated varieties of different crops are susceptible to one disease or another, while some others are susceptible to many diseases. Even resistant cultivars of some of the crop species may become susceptible to some specific diseases in course of time as a result of development of new physiologic races of the pathogen by hybridization or natural mutation or when the environmental conditions are highly favorable for the pathogen and not quite favorable for the host. In this book the authors have given a detailed account of the major diseases of important field crops and horticultural crops, and their management. The text is substantiated with many hand-drawn illustrations, which are of excellent quality and in fact it is the highlight of the book. A on important edible mushrooms commonly grown in India, methods of cultivation of different mushrooms, diseases and pests attacking mushroom beds and mushrooms is also included in the book. This may be quite useful to emerging entrepreneur The book, which has been compiled as per the undergraduate syllabus of agricultural institutions, will also be of use to postgraduate students and to those working in the department of agriculture.

Download or read book Plant Diseases written by J.P. Rai and published by New India Publishing Agency. This book was released on 2014-01-01 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper identification of a problem is the prerequisite for devising the measures of its management as well as for applying the most suitable management strategy available. Plant diseases have always been an associated problem for successful crop cultivation and obtaining optimum profits from this most important enterprise. With advancements in the field of chemical management of plant diseases, we have witnessed a simultaneous increase in the problems related to pesticide application in agriculture. Part of this problem can be attributed to the improper identification of plant diseases, which leads to the use of improper chemical in injudicious amounts. It has, therefore, become necessary to aware the people involved in education, extension and practice of agriculture of proper characterization of plant diseases with the most appropriate management strategy for the disease. In this context, students, extension workers and farmers stand the major clients who must be armed with information on proper identification method and management of a given plant disease. The present book is designed to cater to the needs of undergraduate and postgraduate students of agriculture and biosciences, extension workers and educated progressive farmers. It is aimed to aid them in proper identification of many of the economically important plant diseases with integrated strategies for their respective management. The book may also serve as a guidebook for the professionals in the field of plant disease management for identification and management of plant diseases with minimal resource requirements
Download or read book Diseases Pests Of Fibre Crops written by Subrata Biswas and published by Nipa. This book was released on 2023-06-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive knowledge on the diseases and pests of fibre crops, causing economic damage. It covers major disease and pest damages with the methods to combat them in fibre crop cultivations. The diseases and pests are described elaborately, giving emphasis on both morphological and molecular characteristics of pathogens and biology of different insect pests. The latest and most up-to-date knowledge on these aspects which acquired from diverse, complex, contemporary scientific discoveries in the field of fibre crop diseases and pests are compiled and presented in this book. This book is written in eight major chapters, each representing a certain type fibre crop, except for chapter 2 (two) which deals with both Mesta (kenaf) and Roselle for their similarities in disease and insect pest attacks. Each of the eight chapters is again subdivided into 2 or 3 (only for Chapter 2) subchapters to deal with different types of diseases and pests separately. This is a reference book in textbook format which intended to provide undergraduate, postgraduate and research personnel a means to acquire deeper knowledge on diseases and pests of nine major fibre crops, viz., cotton, jute, kenaf, roselle, sunnhemp, sisal, ramie, flax and hemp. Plant pathologists, entomologists and agricultural research scientists, and in academia, may find much of great use in this book.

This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advisory work, by its very nature, is an intermediary between the re search worker and those who apply the results of his research. The challenge of advisory work is to devise means of and find pathways for transmitting research results to the user, overcome the reluctance of the latter to change, and often combine novel ideas with well-estab lished traditions. Nowhere is this challenge greater than in farming. This is especially true in developing countries, where the gap in the educational level between research workers and farmers may be ex tremely wide. Moreover, village-level advisers are often overburdened with non-professional functions and are not sufficiently backed up by well-trained professional advisers. Thus, in many of these countries there is a serious discrepancy between the knowledge available and that needed and actually applied on the farm. Advisory work in crop protection is no exception, but profits to some extent from two facts: (1) because of the potentially catastrophic nature of pest attack, governments often operate a supervisory crop protection service, the staff of which may be able to dispense some pest control advice; and (2) the staff of pesticide distributors tends to fill, at least in part, the need for advice on how to fight pests and dis eases with chemicals.

Download or read book Recent Advances in the Diagnosis and Management of Plant Diseases written by L.P. Awasthi and published by Springer. This book was released on 2015-11-19 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of “biorational” pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.
