Discover environmentally safe ways to control weeds and pests! Until now farmers have had to choose between using expensive herbicides and fertilizers, which pollute the water table, or watching crop yields drop. All too often, crop yields dropped anyway, despite intensive farming. Allelopathy in Agroecosystems offers fresh hope. It provides an in-depth understanding of allelopathy-the mysterious, complex biochemical interactions among plants and microbes. This little-understood phenomenon plays a large role in agriculture, for good or ill. It can lead to changes in nutrient dynamics, vegetation structure, and species diversity. This comprehensive treatise is the first compendium devoted to explaining and exploring these chemical interactions in agricultural crop systems. Allelopathy in Agroecosystems explains how these interactions can make soil “sick,” especially in intensively cropped areas. This leads to less growth and lower yield. On the other hand, it has great potential as an environmentally safe method of weed and pest management. The fascinating original research presented here will help you understand the complexities of this invisible yet potent force in agriculture. Allelopathy in Agroecosystems examines this interaction as it affects the most important concerns of farmers and agronomists, including: beneficial interactions between crops weed control using crop residues crop rotation natural herbicides genetic engineering soil rhizosphere bacteria improving pastures forest/crop interactions sustainable management of agroecosystems new directions for research International in scope, Allelopathy in Agroecosystems offers an abundance of scientific data on this revolutionary new concept. It offers incalculable potential for rescuing farmed-out land, increasing crop yields, and cutting back on expensive soil additives. Every agronomist, environmental scientist, policymaker, agricultural librarian, and advocate of sustainable farming needs this book.

Allelopathic studies may be defined in various aspects; weed against weed/crop and vice versa. This book focuses on the ways to utilize the allelopathic potential of weeds or crops for controlling weeds in the agroecosystems. Vigorous use of herbicides is poisoning our environment at an alarming rate; allelopathy can be employed as a useful alternative to control weeds naturally under field conditions. The book contains chapters on the history of allelopathy; allelopathic potential of several important crops (rice, wheat, sorghum, maize, mustard, sunflower) and weeds (members of Solanaceae, Convolvulaceae, Asteraceae, Verbenaceae). Moreover, it highlights how the allelopathic potential of these weeds and crops can be employed effectively to suppress weeds under field conditions. The book also discusses topics on the role of allelochemicals in agroecosystems; impact on local flora; biotic stress induced by allelochemicals; mechanism of action of allelochemicals and future prospective of allelopathy. Prepared with basic concepts and importance of allelopathy, this book is intended for the agricultural community, botanists, students and researchers.

The rapidly growing human population has increased the dependence on fossil fuel based agrochemicals such as fertilizers and pesticides to produce the required agricultural and forestry products. This has exerted a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz. , (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz.

This is the first comprehensive and up-to-date reference on the science, mechanism, methodology, and application of allelopathy. The objective of this practical reference is to report on the latest advances by inviting leading scientists to contribute in specific fields. The volume is organized under three major subsections: History of allelopathy, Allelochemicals, allelopathic mechanisms, and bioassays, and Application of allelopathy in agriculture and forestry.

Allelopathy is an ecological phenomenon by which plants release organic chemicals (allelochemicals) into the environment influencing the growth and survival of other organisms. In this book, leading scientists in the field synthesize latest developments in allelopathy research with a special emphasis on its application in sustainable agriculture. The following topics are highlighted: Ecological implications, such as the role of allelopathy during the invasion of alien plant species; regional experiences with the application of allelopathy in agricultural systems and pest management; the use of microscopy for modeling allelopathy; allelopathy and abiotic stress tolerance; host allelopathy and arbuscular mycorrhizal fungi; allelopathic interaction with plant nutrition; and the molecular mechanisms of allelopathy. This book is an invaluable source of information for scientists, teachers and advanced students in the fields of plant physiology, agriculture, ecology, environmental sciences, and molecular biology.
