Biological control is the suppression of populations of pests and weeds by living organisms. These organisms can provide important protection from invasive species and protect our environment by reducing the need for pesticides. However, they also pose possible environmental risks, so biological control interventions must be undertaken with great care. This book enhances our understanding of biological control interactions by combining theory and practical application. Using a combination of historical analyses, theoretical models and case studies, with explicit links to invasion biology, the authors cover biological control of insects, weeds, plant pathogens and vertebrate animals. The book reflects increasing recognition of risks over the past 20 years, and incorporates the latest technological advances and theoretical developments. It is ideal for researchers and students of biological control and invasion biology.

'An absorbing love letter to the English apple tree...lyrical and joyful' - TLS 'A delightful book' - Sunday Times Shortlisted for the Andre Simon Food and Drink Book Award 2016 A Radio 4 Book of the Week 'Wonderful, revelatory ... very moving' - Sheila Dillon, BBC Radio 4 'His ability to laugh at himself, openness to wonder and willingness to go wherever the search takes him make Brown an engaging writer and The Apple Orchard an entertaining journey' - Mail on Sunday Taking us through the seasons in England's apple-growing heartlands, this magical book uncovers the stories and folklore of our most familiar fruit. 'An orchard is not a field. It's not a forest or a copse. It couldn't occur naturally; it's definitely cultivated. But an orchard doesn't override the natural order: it enhances it, dresses it up. It demonstrates that man and nature together can - just occasionally - create something more beautiful and (literally) more fruitful than either could alone. The vivid brightness of the laden trees, studded with jewels, stirs some deep race memory and makes the heart leap. Here is bounty, and excitement.'

The cut flower and foliage industry is a global business with major production locations in North America, South America, Central America, East Africa, Europe, the Middle East, Asia, Australia and New Zealand. Few other horticulture crops are as ubiquitous, yet the production techniques and challenges are universal. This book describes the main international production locations and markets, including current trends and directions. The focus is on production in protected cultivation. The major species - including rose, chrysanthemum, carnation, orchid and gerbera - dominate the global market and these are individually explored in detail. Specialty species and cut foliages are also addressed, as well as significant details of production, including irrigation and fertilization, disease and disease management, and biological control of pests. Finally, the postharvest chapter covers details of harvesting, transporting and delivering high quality flowers that provide an excellent vase life. Highly illustrated with color photos throughout, this is an essential resource for students and researchers in horticulture, growers and producers, and those in the floriculture industry.

This wonderful photographic record of the last year at the site of the New Covent Garden Flower Market, occupied since the 1960s before it moved to its new, more modern premises, captures the essence and heart of what makes a market: its amazing product - the exuberant blooms and foliage - along with the different characters that bring it life as they work there or visit it, as sellers and buyers and porters meet, trade, hustle and bustle, and share a joke. Simon Lycett has bought flowers for his floristry business from this Market for over 30 years, and it has become an essential, and much loved, part of his daily life. The market traders have become like family. Each day there, throughout the year, is different, as the ever-changing seasonal flowers and foliage of spring, summer, then autumn and finally Christmas arrives in the Market hall.

Peanut Agriculture and Production Technology: Integrated Nutrient Management focuses on agricultural techniques and integrated nutrient management of peanuts (Arachis hypogaea L.). Peanuts are the second most important oil crop of India, occupying 5.7 million hectares, with an average production of 0.8 ton/ha, which is 23.5% of the India's total oil seed production. Worldwide annual production of shelled peanuts was 42 million metric tons in 2014. It is the world's 4th most important source of edible oil and the 3rd most important source of vegetable protein. The volume includes basic and advanced information on production, agrotechniques, and integrated nutrient management of Arachis hypogaea L. crop plant. It studies the physiology of the peanut, looking at the proper environmental conditions for optimal growth as well as under various subnormal conditions. It explores the methods of nitrogen application as well as the influence of different sowing dates and population densities to harvest its full yield potential. The book covers methods to achieve balanced nutrition, including using organic manures in groundnut farming to enhance yielding ability. The book will be a rich resource for those in agriculture, horticulture, and allied sciences, particularly for agricultural scientists in plant and crop physiology, agronomy, and soil science. Farm owners and managers of peanut crops and production will also benefit from the information provided in this volume.

Described here are the techniques and fundamental concepts underlying the production and marketing of vegetable crops, particularly those crops that contribute to the commercial vitality of the vegetable industry in the western hemisphere. Those resources which are fundamental to successful crop production, natural, biological and economic, are covered, as well as the vegetable management systems that integrate these resources. Also included is specific information on each of the major vegetable crops, such as history, botanical characteristics, production techniques, pests, harvesting and marketing. In addition, discussions are provided of social conflicts and problems that arise from water and land use practices, pesticide application and conservation.
