Mites pose a serious problem to plants worldwide, attacking crops and spreading disease. When mites damage crops of economic importance the impacts can be felt globally. Mites are among the most diverse and successful of invertebrates, with over 45,000 described species, with many more thousands to be discovered. They are responsible for a significant portion of the losses of crops for food, fibre, industry and other purposes, and require expensive and often controversial pest control measures. Understanding these mites is vital for entomologists, pest researchers, agronomists and food producers. Knowledge of mite pests helps to inform control strategies and optimize the production of economic plants and the agrarian economy. This encyclopedia provides a thorough coverage of the mites and the problems they cause to crops, yet it is easily searchable, organised by mite species and subdivided into helpful headings. It takes a worldwide view of the issue of mites injurious to economic plants, describing mites prevalent in different regions and discussing control methods appropriate in different environments. This book provides an encyclopaedic reference to the major mites, described by family in terms of their internal and external morphology, bio-ecology and family systematics. Methods of mite collection and laboratory study is described, as well as species diagnostic characteristics, worldwide distribution, host plants, identification by the type of damage they cause and control strategies, including chemical and biological intervention and integrated pest management measures. Mites of the following families are included: (Eriophyoidea, Tarsonemidae, Tuckerellidae, Tenuipalpidae, Tetranychidae, Acaridae, Penthaleidae). Mites of Economic Plants is an important resource for students of entomology and crop production, and as a thorough reference guide for researchers and field workers involved with mites, crop damage and food production.

Verticillium wilt is a vascular disease caused by Verticillium dahliae, challenging agronomic production of over 300 crops worldwide. The fungus produces durable microsclerotia in infected plant tissue, which can survive in soil for many years. In the absence of fumigation, suppression of soil populations of V. dahliae relies on natural attrition during periods of nonhost cultivation. However, rotation crops that appear to be nonhosts because they show no symptoms of disease may nevertheless support development of the pathogen and thus negate the benefit of crop rotation. This study was undertaken to evaluate the extent to which common legume cover crops are colonized by V. dahliae and support formation of microsclerotia. Fava bean, bell bean, sunn hemp, sesbania, black-eyed peas, field pea and four vetch species were evaluated under both greenhouse and field conditions. No visual symptoms were observed and stem height of inoculated and control plants were not significantly different. However, V. dahliae was recovered from the stems of all ten crops. When infected stem segments were buried in potting mix, microsclerotia formed on decomposing tissue of eight of the ten crops. The results of this study should help to guide growers in selection of cover crops that will not aggravate problems caused by V. dahliae.

Many of our current agricultural crops are natural or agricultural hybrids (between two or more species), or polyploids (containing more than one genome or set of chromosomes). These include potato, oats, cotton, oilseed rape, wheat, strawberries, kiwifruit, banana, seedless watermelon, triticale and many others. Polyploidy and hybridization can also be used for crop improvement: for example, to introgress disease resistance from wild species into crops, to produce seedless fruits for human consumption, or even to create entirely new crop types. Some crop genera have hundreds of years of interspecific hybridization and ploidy manipulation behind them, while in other genera use of these evolutionary processes for crop improvement is still at the theoretical stage. This book brings together stories and examples by expert researchers and breeders working in diverse crop genera, and details how polyploidy and hybridization processes have shaped our current crops, how these processes have been utilized for crop improvement in the past, and how polyploidy and interspecific hybridization can be used for crop improvement in the future.

Crop improvement using classically induced mutagenesis is now well standardized. Many new promising varieties of different crops have been successfully developed worldwide using both physical and chemical mutagens. Voluminous literature is now available on basic and applied aspects of mutagenesis. The mutation technique has been refined and holds the promise of generating much wider and more desirable variability than classical breeding. Recent advances in technology combined with classical mutation breeding offer new and exciting challenges for the development of new varieties. A global inventory of induced mutagenesis activities for crop improvement is requried. This book covers both basic and applied aspects of mutation and its impact on various crops: it is extremely well prepared and contains a huge volume of information accumulated using classically induced mutagenesis on different crops in different countries. Three key features: Describes the importance of induced mutation in crop plant research and its application to production Highlights new advances in the understanding of plant mutagenesis in crop improvement Contains contributions from major leaders in the field of plant mutation research This volume brings together all the important and relevant literature in the field. It provides a complete account of the mutation breeding of crops, presenting conclusions about the value of the method, its possibilities, limitations, and shortcomings, and the possible difficulties of further application in various crops. The initial chapters deal with the interactions between mutagenic treatment and plant material, such as aspects of mutagenic treatment, postirradiation behavior of shoot apices, and adventitious bud techniques. All available literature is then discussed crop by crop and critically evaluated. This will serve as an extremely comprehensive guide for researchers, teachers, students, and individuals who are interested in using induced mutagenesis as a tool for crop improvement.

Dr Samuel Johnson, that famous eighteenth century lexicographer, said of oats 'A grain which in England is generally given to horses but in Scotland supports the people'. And presumably it was a Scotsman who riposted 'But what people and what horses!' That exchange encapsulates much of the history and role of oats - a cereal, once important as human food in parts of northern Europe but latterly used mainly as animal feed, especially favoured for horses. Although no longer a major food anywhere, oats still have a special and favoured niche in the cuisine of people living in the cooler and wetter regions of some parts of northern Europe. However, there is currently a resurgence of interest in the crop, because there is now considerable scientific evidence to support the view of Scotsmen who never doubted its dietary value. This book - very much an international effort, carefully orchestrated by Robert Welch - traces the origin, history and scientific progress which forms a sound basis for any further crop improvement and for broadening the utilization and marketing of oat products. Should rational consider ations lead to an increase in the importance of this cereal, I, for one, would be glad since I believe the rural landscape is the poorer for the increased rarity of golden fields of rippling oats which I used to be involved in harvesting.

Plant breeding during its evolution has been utilizing biodiversity for producing better crops. Nowadays everyone is concerned about saving the biodiversity. Intensive agricultural practices, climate change and Industrialization are having a straight impact on biodiversity. Use of single new improved varieties of crops for large areas is a big threat for crop biodiversity. Modern breeding approaches are also suggesting going back towards the land races and farmer’s varieties for gene hunting for resistance to various biotic and abiotic stresses. This book includes the description about biodiversity and crop improvement. It also addresses the utilization of plant genetic resources and crop wild relatives for crop improvement through application of traditional plant breeding techniques as well as molecular and genomic approaches. Through this multi authored book an effort has been made to assimilate the most topical results about biodiversity and crop improvement with contemporary plant breeding approaches. Eleven chapters written by leading scientists involved in crop Improvement research worldwide provide sufficient coverage of the major factors impacting utilization of biodiversity for crop improvement.

Remote sensing is a versatile technique facilitating data collection and the investigation of subjects or events without direct physical interaction. This method finds application across scientific disciplines such as geography, hydrology, ecology, oceanography, glaciology and geology. Complementing this, Geographic Information System (GIS) technology emerges as a crucial tool for mapping and assessing feature events on Earth, utilizing data gathered from sensors positioned globally. The integration of remote sensing and GIS brings together fundamental database functions, including statistical analysis and querying, with map data. GIS, as a technology, excels in handling information about places, offering tools for the analysis and display of diverse data sets such as population dynamics, economic development, features and vegetation. Accessible through GIS, these statistics contribute to dynamic presentations, fostering a deeper understanding of Earth's complexities. Furthermore, GIS facilitates database connections, enabling the creation of dynamic presentations. Distinguished by its capabilities, GIS stands out among other systems, finding applications in commercial and public sectors for planning and forecasting outcomes based on observations made by remote sensing satellites. This book serves as a guide to unraveling the intricacies of remote sensing and GIS, providing insights into their integration and diverse applications.
