Book Synopsis Efeito de epoca relativa de plantio no consorcio milho x caupi sobre a presenca de insetos uteis e o manejo economico das pragas by : M. A. W. Quindere
Download or read book Efeito de epoca relativa de plantio no consorcio milho x caupi sobre a presenca de insetos uteis e o manejo economico das pragas written by M. A. W. Quindere and published by . This book was released on 1984 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estudou-se o efeito de epocas relativas de plantio do caupi e do milho cultivados em consorcio e em cultura pura, e seus reflexos sobre aspectos da dinamic populacional das pragas, nos periodos criticos das referidas culturas, levando-se em consideracao niveis de controle economico das mesmas e, o comportamento dos inimigos naturais das pragas. O delineamento experimental adotado foi o de blocos ao acaso, com oito tratamentos e quatro repeticoes. Procedeu-se o levantamento das pragas do caupi e do milho, bem como, de alguns de seus parasitos e predadores, alem de uma serie de outras observacoes, previamente planejadas, visando obter subsidios no sentido de possibilitar o julgamento das hipoteses estabelecidas. Em face as condicoes em que o trabalho foi desenvolvido, chegou-se as seguintes conclusoes: Em consorcio de milho e caupi, com o milho plantado antes do caupi, reduz-se a populacao de ninfas de Empoasca braemeri em relacao ao caupi solteiro; O uso de inseticidas para o controle do Chalcodermus bimaculatus, baseado em nivel de danos causados pela praga ao caupi, devendo as inspecoes de campo iniciarem-se com o aparecimento das primeiras vagens; O uso de defensivos, baseado em nivel de controle economico, permite a sobrevivencia de inimigos naturais, mantendo as pragas em niveis sub economico; As fases 1 e 2 do milho, confirmam-se como criticas ao ataque da Spodoptera frugiperda.

Book Synopsis Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes by : A. Ciancio
Download or read book Integrated Management and Biocontrol of Vegetable and Grain Crops Nematodes written by A. Ciancio and published by Springer Science & Business Media. This book was released on 2007-12-08 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume of the IMPD series describes aspects related to the most important phytoparasitic nematodes, considering the integration of biological control methods with other management practices and technologies, including the use of predatory nematodes and microbial rhizosphere antagonists. A focus is given on regional issues. A review on nematode management in cotton is integrated by a chapter on management of nematodes on wheat. New technologies are also revised.
Book Synopsis Advances in Fungal Biotechnology for Industry, Agriculture, and Medicine by : Jan S. Tkacz
Download or read book Advances in Fungal Biotechnology for Industry, Agriculture, and Medicine written by Jan S. Tkacz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, filamentous fungi have grown in commercial importance not only in the food industry but also as sources of pharmaceutical agents for the treatment of infectious and metabolic diseases and of specialty proteins and enzymes used to process foods, fortify detergents, and perform biotransformations. The commercial impact of molds is also measured on a negative scale since some of these organisms are significant as pathogens of crop plants, agents of food spoilage, and sources of toxic and carcinogenic compounds. Recent advances in the molecular genetics of filamentous fungi are finding increased application in the pharmaceutical, agricultural, and enzyme industries, and this trend promises to continue as the genomics of fungi is explored and new techniques to speed genetic manipulation become available. This volume focuses on the filamentous fungi and highlights the advances of the past decade, both in methodology and in the understanding of genomic organization and regulation of gene and pathway expression.

Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
Book Synopsis Nematode Interactions by : M. Wajid Khan
Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.
