Pesticides in Agriculture and the Environment (Books in Soils, Plants, and the Environment, 90)

Discussing the range of effects of pesticides on food and human safety, water quality, wildlife, and pest management, this book explores the agricultural, economic, and regulatory factors that affect pesticide use. It examines crop and pest ecology, integrated pest management principles, and emerging analytical tools to improve the efficacy and cost-efficiency of pest control. Expert contributions describe the current status of pesticides issues and those related to pest management. The book summarizes advances and trends in the crop protection industry, such as integrated pest management, hybrid seed and generic pesticide production, improved pesticide formulations, and plant biotechnology. Booknews Contains ten contributions describing the current status of pesticide issues and those related to the broader topic of pest management. Coverage includes integrated pest management (IPM), how it evolved, the current state of risk assessment, biological control techniques, the economics of pest management and pest management legislation, and the current state of analytical methods used by international regulators. Also addressed are specific issues for pest management on minor crops, the current approach and issues related to chemical application technology, the important issues of resistance of pests to pesticides and management of that resistance, and a look at the future for both pest management chemistry and the state of the pest management industry. Contributors include entomologists, pathologists, researchers, chemists, resource economists, and others, primarily associated with universities and the US Department of Agriculture. Annotation c.

emerging analytical tools to improve the efficacy and cost-efficiency of pest control The scientific and technical development of integrated pest management (IPM) methods during the twentieth century were covered by several publications of the 1990s [1-4], but the policy aspects of IPM have received less attention.
