This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the International Conference on Effects of Crop Rotation on Potato Production in the Temperate Zones. This conference was held in the International Agricultural Centre at Wageningen, The Netherlands, August 14 - 19, 1988, under the auspices of the European Association for Potato Research (EAPR), the Potato Association of America (PAA) and the Dutch National Council for Agricultural Research (NRLO). The length of rotations affect the performance of potato crops and yields are often reduced if rotations are too short. The kinds of crops within a rotation will also affect potato performance, especially those grown in the previous season. It was a major aim of the conference to bring together specialists of various disciplines to examine these determinants of potato yield. The Organizing Committee is glad that all relevant aspects of the theme are highlighted in these proceedings. The contents of the contributions are primarily left to the responsibility of the authors. J. Vos C.D. van Loon G.J. Bollen ORGANIZATION OF THE CONFERENCE The European Association for Potato Research (EAPR) and the Potato Association of America (PAA) nominated representatives in the Conference Committee. PAA was represented by prof. dr E.E. Ewing (Ithaca, USA) and by dr R.E. Thornton (Pullman, USA); EAPR was represented by prof. dr J.C. Holmes (Edinburgh, UK), ir C.D. van Loon (Lelystad, NL), and dr ir J. Vos (chairman; Wageningen, NL).
Download or read book Integrated Nematode Management written by Richard A. Sikora and published by Cabi. This book was released on 2021 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant parasitic nematodes are costly burdens of crop production, causing an estimated US$80 - 118 billion per year in damage to crops. They are associated with nearly every important agricultural crop, and are a significant constraint on global food security. Regulations on the use of chemical pesticides have resulted in growing interest in alternative methods of nematode control. Future changes in climate, cropping systems, food habits, as well as social and environmental factors also affect the options for nematode control. Taking a systematic crop by crop approach, this book: Outlines the economic importance of specific plant parasitic nematode problems on the major food and industrial crops. Presents the state-of-the-art management strategies that have been developed to reduce specific nematode impacts, and outlines their limitations. Contains case studies to illustrate impact in the field. Aims to anticipate future changes in nematode disease pressure that might develop as a result of climate change, and new cropping systems.

Download or read book Plant Parasitic Nematodes in Sustainable Agriculture of North America written by Sergei A. Subbotin and published by Springer. This book was released on 2018-12-17 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are recognized as one of the greatest threats to crop production throughout the world. Estimated annual crop losses of $8 billion in the United States and $78 billion worldwide are attributed to plant parasitic nematodes. Plant parasitic nematodes not only cause damage individually but form disease-complexes with other microorganisms thereby increasing crop loss. Nematode diseases of crops are difficult to control because of their insidious nature and lack of specific diagnostic symptoms which closely resemble those caused by other plant pathogens and abiotic diseases. Future developments of sustainable management systems for preventing major economical agricultural losses due to nematodes is focused on strategies that limit production costs, enhance crop yields, and protect the environment. This book presents a first compendium and overview for nematode problems and their management across North America. Each chapter provides essential information on the occurrence and distribution of plant parasitic nematodes, their major crop hosts, impact on crop production and sustainable management strategies for each region of the continent including, Canada, Mexico and all states of the USA. For each region, a thematic overview of changes in crop production affected by plant parasitic nematodes and their management strategies over time will provide invaluable information on the important role of plant parasitic nematodes in sustainable agriculture.

Download or read book Soilborne Microbial Plant Pathogens and Disease Management Volume Two written by P. Narayanasamy and published by CRC Press. This book was released on 2019-10-08 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop disease management strategies revolve around the principles of exclusion, eradication and immunization. Cultural practices are aimed at preventing or reducing the accumulation of pathogen population (inoculum). Development of cultivars with genetic resistance by transgressing resistance gene(s) through traditional breeding procedures or biotechnological techniques is the most effective and acceptable strategy, as it is environment-friendly and does not need any additional cost to the grower. Assessment of different grades of resistance of cultivars or genotypes to soilborne microbial pathogens has been possible by quantifying pathogen populations or their DNA contents in the test plants by applying biological and molecular methods. This second volume of a two-volume set focuses on the soilborne microbial plant pathogens and the diseases caused by them. The book provides information on ecology and epidemiology of soilborne microbial plant pathogens and various strategies applicable for effective management of diseases. Chapters cover exclusion and prevention strategies; improvement of host plant resistance; biological management; application of chemicals; and integration of these disease management strategies. Features Discusses various aspects of soilborne microbial plant pathogens to develop effective methods of managing diseases. Presents information on epidemiology and ecology of soilborne microbial plant pathogens. Facilitates the application of management strategies alone or in combination with others for effective suppression of disease development. Features information on application of biotic and abiotic biological control agents (BCAs) to suppress pathogen development either by directly acting on the pathogen(s) or indirectly by enhancing host resistance to the pathogens. Employs biotic and abiotic biocontrol agents either to replace or reduce the use of chemicals is an achievable approach for managing the soilborne microbial pathogens.

This book was released on 2019-10-08 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soilborne microbial plant pathogens including oomycetes, fungi, bacteria and viruses cause several economically important destructive diseases and the symptoms of infection can be recognized only after the pathogen has invaded many tissues primarily vascular tissues of susceptible plants. This condition places formidable challenges in investigating different aspects of host-microbial pathogen interactions. Early detection of infection and precise identification, differentiation, and quantification of the microbial plant pathogens in plants, soil and water sources are essential requirements for development of effective tactics to reduce the incidence and spread of the diseases caused by them. As the microbial plant pathogens differ in their virulence and sensitivity to the environment and chemicals applied, it is imperative to assess the extent of variability in the concerned pathogens. This first volume of a two-volume set introduces disease-causing microorganisms including oomycetes, fungi, bacteria, and viruses found in soils. It focuses on the biology, detection, and identification of soilborne bacterial, fungal, and viral plant pathogens. This volume discusses various techniques based on biological, immunological and genetic properties of the pathogens indicating their advantages and limitations for selecting the appropriate technique to fulfill the requirements. Features: Presents techniques useful for detection, identification, quantification of microbial plant pathogens in plants, soil, and irrigation water from waterbodies. Highlights subversive activities of viruses, resulting in the breakdown of host defense systems. Discusses RNA silencing in infected plants by viruses and posttranscriptional gene silencing (PTGS) functioning as an endogenous mechanism in plants against virus infection. Presents information on methods of assessment of genetic variability and sensitivity of microbial plant pathogens to chemicals and adverse environmental conditions.
