Book Description
Pesticide Profiles: Toxicity, Environmental Impact, and Fate is like three books in one-it is a profile containing specific information about 137 pesticides, a primer of environmental toxicology, and an extensive trade name index. Profiles of each pesticide contain regulatory information, toxicity assessments, environmental fate data, physical properties, and acceptable exposure limit values. What these values and data mean in terms of human toxicity is clearly interpreted as well. The book also describes the meaning of carcinogenicity and how it is assessed in non-technical terms the non-expert can understand. Readers with a technical background are provided with the data to make their own judgments. In addition to information about specific pesticides, there are sections on general classes of pesticides, such as organophosphates. This information allows readers to make inferences about any pesticide in a class, even if a profile is not provided. Pesticide Profiles: Toxicity, Environmental Impact, and Fate goes beyond the usual listings of toxicity values or environmental half-lives to offer a broad understanding to readers of various backgrounds and interests.

Book Description
In a convenient, single-source reference, this book examines plant growth substances and their relationship to a wide range of physiological processes, ranging from seed germination through the death of the plant. If offers a clear illustration of the pragmatic uses of plant substances in agriculture and demonstrates how basic laboratory research has translated into increased production and profit for the grower. This work begins by building a solid foundation in the subject, which contains historical aspects and fundamental concepts, and provides a methodology for extraction, purification, and quantification of plant growth substances. This forms the basis for understanding the ensuing chapters that explore the many processes involving plant growth substances, including: * seed germination * seedling growth * rooting * dormancy * juvenility * maturity * senescence * flowering * abscission * fruit set * fruit growth * fruit development * premature drop * ripening * promotion of fruit drop * tuberization * photsynthesis * weed control. Providing a detailed examination of plant growth substances and their relationships to specific physiological plant processes, Plant Growth Substances gives students, researchers, and professionals a much needed reference.

Book Description
This volume addresses recent developments in weed science. These developments include conservation agriculture and conservation tillage, climate change, environmental concerns about the runoff of agrochemicals, resistance of weeds and crops to herbicides, and the need for a vastly improved understanding of weed ecology and herbicide use. The book provides details on harnessing knowledge of weed ecology to improve weed management in different crops and presents information on opportunities in weed management in different crops. Current management practices are also covered, along with guidance for selecting herbicides and using them effectively. Written by experts in the field and supplemented with instructive illustrations and tables, Recent Advances in Weed Management is an essential reference for agricultural specialists and researchers, government agents, extension specialists, and professionals throughout the agrochemical industry, as well as a foundation for advanced students taking courses in weed science.

Book Description
The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).
