Date palm, Phoenix dactylifera L. (Arecales: Arecaceae), is an important palm species cultivated in the arid regions of the world since pre-historic times and traditionally associated with the life and culture of the people in the Middle-East and North Africa which are the pre-dominant date palm growing regions worldwide. The Food and Agriculture Organization of the UN estimates that there are over 100 million date palms with an annual production of over 7.5 million tonnes A recent report on the arthropod fauna of date palm, enlists 112 species of insects and mites associated with date palm worldwide including 22 species attacking stored dates. Enhanced monoculture of date palm in several date palm growing countries coupled with climate change, unrestrained use of chemical insecticides and extensive international trade is likely to impact the pest complex and the related natural enemies in the date agro-ecosystems. In view of the importance of date palm as an emerging crop of the future and the need to develop and deploy ecologically sound and socially acceptable IPM techniques, this book aims to comprehensively address issues related to the biology and sustainable management of major insect and mite pests of date palm by assessing the current IPM strategies available, besides addressing emerging challenges and future research priorities. The issues pertaining to the role of semiochemicals in date palm IPM involving new strategies revolving around “attract and kill” and “push-pull” technologies, phytoplasmas and their insect vectors with implications for date palm, innovative methods for managing storage pests of dates and knowledge gaps in devicing sustainable strategies for the management of red palm weevil, Rhynchophorus ferrugineus (Olivier) are also addressed
A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book. This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.
The Mediterranean region has more than 25 million hectares of Mediterranean forests and about 50 million hectares of other Mediterranean wooded lands. They make crucial contributions to rural development, poverty alleviation, food security, as well as, the agricultural, water, tourism, and energy sectors. Changes in climate, societies, and lifestyles to create appropriate financial incentives and tools. in the Mediterranean region could have serious negative consequences for forests, with the potential to lead to the loss or diminution of those contributions and to a wide range of economic, social and environmental problems. In the future, Mediterranean forests will support agriculture and human wellbeing. It is therefore crucial to improve policies, practices, and to promote sustainable management to provide social and economic benefits as well as to increase the resilience of ecosystems and societies. This new edition of the State of Mediterranean Forests aims to demonstrate the importance of Mediterranean forests to implementing solutions to tackle global issues such as climate change and population increase. Part 1: The Mediterranean landscape: importance and threats. Despite the important natural capital provided by Mediterranean forests, they are under threats from climate change and population increase and other subsidiary drivers of forest degradation. Part 2: Mediterranean forest-based solutions. Forests and landscape restoration, adaptation of forests and adaptation using forests, climate change mitigation, and conserving biodiversity are additional and complementary approaches to address the drivers of forest degradation to the benefit of populations and the environment. Part 3: Creating an enabling environment to scale up solutions. To scale up and replicate forest-based solutions, there is a need to change the way we see the role of forests in the economy, to put in place relevant policies, more widespread participatory approaches, to recognize the economic value of the goods and services provided by forests and, ultimately, to create appropriate financial incentives and tools.
The papers contained in this book were presented at a NATO Advanced Research Workshop (ARW) held at Cape Sounion, Athens, Greece, 19-24 May, 1991. The twenty-eight more comprehensive papers represent the key subjects of the ARW covered by invited speakers. The thirty-four short papers pre sented in a research format are contributions of those invited to participate in the ARW. There was a total of 70 participants from 21 countries. The objectives of the ARW were as follows: to review current knowledge of biological control of plant diseases and plant parasitic nematodes, with emphasis on mechanisms at the molecular, cellular, organismal, and ecosystem level; to examine and expand on current concepts and synthesize new concepts; to identify and prioritize limitations in the use of biological control for plant diseases and nematodes and the scientific research needed to overcome these limitations; and to develop strategies for biological control through management of resident agents or introduction of natural or modified agents.
This series originated during a visit of prof. K. G. Mukerji to the CNR Plant Protection Institute at Bari, Italy, in November 2005. Both editors convened to produce a series of five volumes focusing, in a multi-disciplinary approach, on recent advances and achievements in the practice of crop protection and integrated pest and disease management. This fourth Volume deals with management of nematodes parasitic of tree crops, and includes a section on tropical fruit crops and commodities, as well as a second section on tree crops from more temperate areas. The latter also includes a chapter updating the current knowledge about the pine wood nematode, Bursaphelenchus xylophilus. Volume 4 flanks Volume 2 of this IMPD series, which focused on management of vegetable and grain crops nematodes. Nematodes are a very successful, diversified and specialised animal group, present in nature in any ecological niche. Among nematode species, only a reduced number feeds on plants, of which a few species cause severe economic impacts on crop productions. Plant parasitic nematodes represent an important concern for a broad range of agricultural productions and systems, worldwide. This statement explains the attention devoted in last decades to nematodes, and the research and technical efforts invested for their control.
