Arboriculture & Urban Forestry 42(3): May 2016 Arboriculture & Urban Forestry 2015. 42(3): 213–214 213 Book Review O’Brien, D.D., and G.W. Hudler. 2011. Features from the Past for the Future. Branching Out: An In- tegrated Pest Management Newsletter for Trees and Shrubs. Department of Plant Pathology and Plant- Microbe Biology, Cornell University, Ithaca, New York, U.S. 296 pp. Technical Publication-2012-001. Intended for technical practitioners whom are con- cerned with the management of ornamental trees and shrubs (i.e., arborists, urban foresters, and green industry professionals), Features from the Past for the Future is a compilation of 18 years of feature articles appearing in the ever-popular newsletter produced by Cornell University, Branching Out: An Integrated Pest Management Newsletter for Trees and Shrubs. As an extensively developed technical publi- cation, this 296-page spiral-bound resource is infor- mative, enlightening, and practical. Through years of careful observation and experience, O’Brien and Hudler earned their positions as two of the foremost authorities on pest management in ornamental landscapes. This publication leverages their experi- ence and perspective to help Plant Health Care pro- fessionals manage existing pest-related outbreaks. Formatted out in a user-friendly manner and with an easy-to-read table of contents, this book quickly sets the tone behind the authors’ motives to create a resource that synthesizes the feature articles from Branching Out, as well as provides references for further information, notably in two internationally renowned texts, also produced by Cornell Univer- sity: Insects that Feel on Trees and Shrubs (second edi- tion) by W.T. Johnson and H.H. Lyon, and Diseases of Trees and Shrubs (second edition) by W.A. Sin- clair, H.H. Lyon, and W.T. Johnson. A description of the 50°F threshold as being the basis for Grow- ing Degree Day (GDD) calculations is also outlined early in the text, as GDDs are generally considered a reliable environmental marker relative to pest devel- opment throughout the growing season. The authors also take the opportunity to let the reader know that the pesticide recommendations that would nor- mally found in Branching Out articles have been removed (as pesticide labels and regulations may vary from region to region, and even change). The book is divided into three practical sec- tions with further subdivisions: Insects (and other arthropods), Diseases, and Management. Insects are initially discussed under the heading Host Specific Pests, and some of the most well- known (and timely) insects are highlighted in this section, including emerald ash borer (Agrilus planipennis), birch leafminer (Agrilus planipen- nis), bronze birch borer (Agrilus anxius), hemlock woolly adelgid (Adelges tsugae), and viburnum leaf beetle (Pyrrhalta viburni). The pests under the General Interest heading include well-known actors, like ambrosia beetles (Xylosandrus spp.), Asian longhorned beetle (Anaplophora glabripen- nis), black vine weevil and white pine weevil (Otiorhynchus sulcatus), (Pissodes strobi), as well as sawflies, scales, and a well-known arthropod pest, spruce spider mite (Oligonchus ununguis). Host Specific Diseases include beech bark dis- ease (Nectria spp.), bleeding cankers on European beech (Phytophthora spp.) and horsechestnut (Pseu- domonas sp.), oak wilt (Ceratocystis fagacearum), and thousand cankers (Geosmithia morbida). Dis- eases of General Interest detailed Armillaria root rot (Armillaria spp.), bacterial leaf scorch (Xylella fastidiosa), and a plethora of general canker diseases (e.g., Botryosphaeria spp., Eutypella spp., Nectria spp., Cytospora spp.), needle rusts (e.g., Coleospo- rium spp., Pucciniastrum spp., Uredinopsis spp., Milesina spp.), cedar rusts (Gymnosporangium spp.), and the much talked about generalist-pathogen, Verticillium wilt (Verticillium dahliae). This section, no doubt of particular interest to commercial arbor- ists/community foresters concerned with urban risk tree issues, closes with a Top 8—a list of wood decay fungi, complete with excellent color photos and succinct descriptions for easy identification. ©2016 International Society of Arboriculture
