Book Description
Nontarget Effects of Biological Control is the first book of its kind. The environmental safety of biological control has come under scrutiny due to several areas of concerns: the irreversibility of alien introductions, the prevalence of host switching to innocuous native or beneficial species, dispersal of the biocontrol agent to new habitats away from croplands, and the lack of research on the efficacy and impact of biocontrol attempts. The debate has been strongly polarized between conservationists and biological control practitioners. Nontarget Effects of Biological Control proposes that retrospective analyses of systems in place in which nontarget effects are now documented or suspected provide the necessary information for planning and evaluating future releases to reduce risk. The book presents case histories of past biological control introductions from island and continental ecosystems.

Book Description
The way the nation manages pests is changing because of efforts to reduce the reliance on conventional pesticides. Driving this change is strong public opinion coupled with action by Congress and by federal and state agencies. At the same time, pest control needs are rising. Many important pests are now resistant to formerly effective chemical controls. And new pests continue to enter the country or spread to new locations where they threaten agriculture, native ecosystems, or human health. The farmers, foresters, ranchers, and others who seek to prevent excessive pest damage are increasingly aware of the shortcomings of conventional pest control approaches.

Book Description
More and more farmers are adopting a diverse range of alternative practices designed to reduce dependence on synthetic chemical pesticides, fertilizers, and antibiotics; cut costs; increase profits; and reduce the adverse environmental consequences of agricultural production. Alternative Agriculture describes the increased use of these new practices and other changes in agriculture since World War II, and examines the role of federal policy in encouraging this evolution, as well as factors that are causing farmers to look for profitable, environmentally safe alternatives. Eleven case studies explore how alternative farming methods have been adoptedâ€"and with what economic resultsâ€"on farms of various sizes from California to Pennsylvania.
