This first edition text presents the basic principles of integrated pest management as they apply to plant pathogens, weeds, nematodes, mollusks, arthropods, and vertebrates. It reinforces the wisdom and soundness of the integrated pest management (IPM) approach to crop protection, which attempts to limit the deleterious effects of pests in ways that are environmentally, economically, and socially acceptable. A glossary and supplemental readings are offered to expand on the explanations and definitions provided in the book, which is illustrated with numerous photographs, line drawings, and graphs.
