Book Description




Biologically based technologies for pest control.


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.
