Principles of Plant and Anirmal Pest Control A six-volume series from the Committee on Plant and Animal Pests Agricultural Board Division of Biology and Agriculture, NRC

Volume 1 Plant-Disease Development and Control ISBN 0-309-01596-0; 1968, xvi + 205 pages, paperbound, $4.75

This report identifies and examines the primary, secondary, and subsidiary principles that influence plant-disease development and control; outlines the current state of knowledge relating to the principles of effective control; and cites significant supplementary sources of information on the subject. Also included are a glossary of terms relating to plant pathology and a complete index of plants and diseases discussed in the text.

Volume 2 Weed Control ISBN 0-309-01597-9; 1968; xviii + 476 pages, paperbound, $8.00

Weed Control examines current practices and the state of knowledge in the field and outlines major areas of needed research. This useful report presents a com- prehensive review and summary of the basic principles of the preventive, biological, managerial, physical, and chemical weed-control methods that can be used to increase the yield of farms, rangelands, and forests. Many information sources dealing with specific weed- control problems are listed in the report's extensive bibliography.

Volume 3 Insect-Pest Management and Control ISBN 0-309-01695-9; 1969, xxii +- 508 pages, paperbound, $10.50

This volume describes not only well-established concepts but also current hypotheses that guide efforts to regulate the abundance or prevent the establish- ment and spread of insects that are harmful to man. It provides an introduction to the ecological back- ground underlying pest management, discusses principles related to the entire range of control procedures, and describes the types of controls that may be suitable for representative insect-pest problems.

Volume 4 Control of Plant-Parasitic Nematodes ISBN 0-309-01696-7; 1968, xii + 166 pages, paperbound, $5.00

Focusing upon the growing importance of nematology, this volume considers in detail the principles of controlling nematode infestations of plants and

96'

indicates areas where further research is necessary. It discusses the basic principles of the biological, physical, and chemical nematode-control methods that can be used to reduce infestations and improve levels of food production. It also emphasizes the need for better training of nematologists and for additional research on nematode physiology, biochemistry, ecological relationships, and host-parasite inter- actions.

Volume 5 Vertebrate Pests: Problems and Control ISBN 0-309-01697-5; 1970, x + 153 pages, paperbound, $5.25

This report examines and assesses areas of man- vertebrate-pest conflicts and emphasizes man's responsibility to use only those preventive or correc- tive measures that are ecologically sound and socially acceptable and that affect only the target species or individuals. It also describes pest situations and principles of control measures involving fishes, amphibians and reptiles, birds, small mammals, predatory animals, and big game, indicating that we lack complete information concerning the mechanical devices, repellents, and poisons with which vertebrate pests are controlled.

Volume 6 Effects of Pesticides on Fruit and Vegetable Physiology

ISBN 0-309-01698-3; 1968, x + 90 pages, paper, $3.95

Among the topics discussed in this report are the effects of the pesticide compounds on seed germina- tion, vegetative development, sexual reproduction, development of storage organs, maturation, harvest and post-harvest behavior, and nutritional value and market quality of fresh and processed food products. A list of more than 600 references serves to document statements and conclusions presented in the text and directs the reader to additional sources of information on the subject.
