Integrated Pest Management (IPM) has been taught in the Department of Entomology at the University of Minnesota since 1966. Over the years, we've used many different textbooks for this course, supplementing these with primary references and more recently with web resources. We've never lacked for quality information resources to use in teaching our course, especially so in recent years, but we've never felt satisfied that any one textbook provided the breath of coverage of all the IPM related topics we think need to be included in a university-level course. We recognized that our expectations might be unrealistic since such broad coverage could make for a book of such size and cost that it wouldn't be appropriate to adopt as a required textbook.

We attempted to overcome these challenges by developing our own online textbook, Radcliffe's IPM World Textbook, http://ipmworld.umn.edu. Our concept for creating this website was that we'd solicit content from a cadre of internationally recognized experts with the goal eventually of a comprehensive online IPM resource having “chapters” covering all aspects of IPM. Our primary objectives in creating this website were to provide (1) a venue for easily maintaining and updating “state of the art” information from the world's leading experts on all aspects of IPM, and (2) a resource economically deliverable anywhere in the world that could be freely downloaded for use by students, teachers and IPM practitioners.
