Pest Management Programs for Deciduous Tree Fruits and Nuts attempts to present the current status of pest management programs in orchard ecosystems. The book is a collection of papers from a symposium convened on the subject for the 1977 National Meeting of the Entomological Society of America and invitational papers on commodities not covered during the symposium. In recent years, books have appeared on "integrated pest management (IPM)"; however, most of these have concentrated on field crop IPM with an occasional chapter on fruits. No publication presently exists which brings together information on the pest management programs currently being conducted on the major nut crops, almonds, pecans and walnuts. Because it is the first treatment for almonds and walnuts, the authors of these chapters have attempted not only to present the current IPM technology but the historical data which led to the contemporary programs. Two chapters appear on pecan IPM. The first concentrates on the development of a management program for the pecan weevil, the key arthropod pest of pecans, while the second discusses the implementation of pilot pecan IPM programs in two southeastern states. The latter chapter illustrates that even with a limited data bank, the pesticide load in pecan orchards can be reduced by the adoption of the IPM approach to pest control.

Winner of the National Book Critics Circle Award for Autobiography A New York Times 2016 Notable Book National Best Seller Named one of TIME magazine’s "100 Most Influential People" An Amazon Top 20 Best Book of 2016 A Washington Post Best Memoir of 2016 A TIME and Entertainment Weekly Best Book of 2016 An illuminating debut memoir of a woman in science; a moving portrait of a longtime friendship; and a stunningly fresh look at plants that will forever change how you see the natural world Acclaimed scientist Hope Jahren has built three laboratories in which she’s studied trees, flowers, seeds, and soil. Her first book is a revelatory treatise on plant life—but it is also so much more. Lab Girl is a book about work, love, and the mountains that can be moved when those two things come together. It is told through Jahren’s remarkable stories: about her childhood in rural Minnesota with an uncompromising mother and a father who encouraged hours of play in his classroom’s labs; about how she found a sanctuary in science, and learned to perform lab work done “with both the heart and the hands”; and about the inevitable disappointments, but also the triumphs and exhilarating discoveries, of scientific work. Yet at the core of this book is the story of a relationship Jahren forged with a brilliant, wounded man named Bill, who becomes her lab partner and best friend. Their sometimes rogue adventures in science take them from the Midwest across the United States and back again, over the Atlantic to the ever-light skies of the North Pole and to tropical Hawaii, where she and her lab currently make their home. Jahren’s probing look at plants, her astonishing tenacity of spirit, and her acute insights on nature enliven every page of this extraordinary book. Lab Girl opens your eyes to the beautiful, sophisticated mechanisms within every leaf, blade of grass, and flower petal. Here is an eloquent demonstration of what can happen when you find the stamina, passion, and sense of sacrifice needed to make a life out of what you truly love, as you discover along the way the person you were meant to be.

This manual contains a wealth of information to help you diagnose abiotic disorders in landscape plants – disorders caused by environmental, physiological or other nonbiological factors. You’ll learn how to diagnose injury symptoms from over 20 different abiotic agents including water deficit, nutrient deficiencies, salinity, pH, sunburn, air pollution, herbicide and other chemical phytotoxicities, mechanical injuries, lightning, wind, and hail. You’ll also learn how to develop a step-by-step diagnostic strategy. Included are strategies, techniques, and tools you can use in diagnosing plant problems, common injury symptoms and their abiotic causes, and plant traits that can resemble abiotic disorders. Illustrated with 319 color photographs and 38 tables, this book is a "must-have" for the library of every landscape professional.

Advisory work, by its very nature, is an intermediary between the re search worker and those who apply the results of his research. The challenge of advisory work is to devise means of and find pathways for transmitting research results to the user, overcome the reluctance of the latter to change, and often combine novel ideas with well-estab lished traditions. Nowhere is this challenge greater than in farming. This is especially true in developing countries, where the gap in the educational level between research workers and farmers may be ex tremely wide. Moreover, village-level advisers are often overburdened with non-professional functions and are not sufficiently backed up by well-trained professional advisers. Thus, in many of these countries there is a serious discrepancy between the knowledge available and that needed and actually applied on the farm. Advisory work in crop protection is no exception, but profits to some extent from two facts: (1) because of the potentially catastrophic nature of pest attack, governments often operate a supervisory crop protection service, the staff of which may be able to dispense some pest control advice; and (2) the staff of pesticide distributors tends to fill, at least in part, the need for advice on how to fight pests and dis eases with chemicals.
