Download or read book Weed Biology and Management written by Inderjit and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.

Download or read book Root Interactions and Evaluation of Agroforestry and Intercropping Systems in Benin West Africa written by Sigmund Johannes Lose and published by . This book was released on 2003 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: About the book In West Africa, traditional smallholder fallow systems urgently need sustainable intensification while maintaining soil fertility. Agroforestry systems were propagated to attain these targets. Earlier work, however, had not shown the expected positive effects on yield of the interplanted staple crops due to shading as well as root competition for nutrients and water. From 1995 until 1999, within the frame of the special research programme 308 (1985-1999) "Adapted farming in West Africa" of the University of Hohenheim, root studies were carried out in Southern Benin using the profile wall method for direct root observation and destructive soil monolith sampling. To estimate sustainability of the various treatments, i.e. fertilised, annual and perennial alley cropping in comparison to local practice, and production systems, i.e. maize-cassava intercropping, cassava sole-cropping as well as alley vs. block arrangement of perennial leguminous trees, yield trends were calculated for the three central trial sites at different edapho-climatical ecozones. Additionally, to quantify the complex interactions in agroforestry as well as in intercropping systems, data were used in system process modelling to give quantification of sustainable land management.

Download or read book The Granulovirus of the Potato Tuber Moth Phthorimaea Operculella Zeller written by Marc Sporleder and published by . This book was released on 2003 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potato tuber moth Phthorimaea operculella (Lepidoptera: Gelechiidae) is the most important pest in potato production in the tropics and subtropics. Faced with serious and increasing problems due to the extensive use of chemical pesticides to control this pest, safer alternatives such as the use of entomopathogens are of growing interest. The research presented here focus on the efficient integration of the endemic granulovirus infecting the potato tuber moth (PoGV) as biopesticide into IPM strategies. The investigations include basic research on the granulovirus-host interaction and ecology which allows a comprehensive understanding of the system and how the system is influenced by environmental factors, and applied research to improve the virus mass propagation technique and the UV-stability of the virus. The results presented allow differentiation between conditions occurring in different agroecological regions for appropriate management of the virus.

Download or read book Integrating New Technologies for Striga Control written by Gebisa Ejeta and published by World Scientific. This book was released on 2007 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Witchweeds (Striga species) decimate agriculture in much of Africa and parts of Asia, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers. Several years of research have provided promising technologies, based on the fundamental biology of the parasite?host associations, for dealing with this scourge. However, there is an apparent realization that these technologies will fail because highly successful weeds such as Striga evolve resistance to all types of controls unless proven methods are integrated with each other for a more sustainable solution.Integration is often an anathema to basic scientists who typically deal with single variables and solutions. However, key leaders in the development of the new knowledge-based control strategies, already in the field and under development, recently joined forces to develop strategies and projects in order to integrate the technologies in a symposium in Ethiopia in November 2006. The encouraging results are described in this peer-reviewed book, authored by leaders in the field who have been supplying the basic biology, genetics, biochemistry, and molecular information that have offered insights and generated technologies in how to deal with Striga.

Available in PDF, EPUB and Kindle. Book excerpt: This book was written in response to significant recent advances in understanding the mechanisms of parasitism in the Orobanchaceae, and breakthroughs in the control of the parasitic weeds Striga and Orobanche. It consists of 26 contributions by internationally recognized leading scientists. The main book chapters are grouped into two parts: · Part I – The Orobanchaceae and Their Parasitic Mechanisms · Part II – The Weedy Orobanchaceae and Their Control The first part provides cutting-edge information on all key aspects of plant parasitism, such as the structure, development and function of the haustorium; nutrient transfer and the physiology of the parasite-host association; host reaction to parasitic plants; seed production and germination; the strigolactones and host-parasite signaling mechanisms; the parasite genome, phylogenetics, evolution and epigenetics; and ecology. Topics of the second part include: the problem posed by the weedy parasites; population diversity and dynamics; molecular diagnosis of seed banks; and detailed discussion of the various management strategies, including agronomic, chemical and biotechnological approaches, as well as host breeding for resistance, allelopathy and biological control. This book is intended for plant scientists, university lecturers and students, agronomists and weed specialists, breeders and farmers, extension personnel and experts in tropical and subtropical agriculture.

Download or read book A Technical Manual for Parasitic Weed Research and Extension written by J. Kroschel and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic weeds of the families Cuscutaceae, Orobanchaceae and Scrophulariaceae are considered to be among the major problems facing agriculture in the Tropics and Subtropics. In the last decades, enormous efforts have been made and success achieved by scientists all over the world in gaining a better understanding of their biology and ecology as well as of control methods. However, no substantial reduction of infestation has been achieved in the past and control strategies specific to the different parasites, crops and farming systems must be further developed or adapted and realised among a wider farming population with suitable extension methods. This `Technical Manual' provides up-to-date methodologies for various aspects of research and extension related to parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the intention to support scientists and extension workers of international and national research and extension institutes and universities, who are either new to the subject or plan to apply further techniques they are not yet familiar with.
