This new, third edition, includes a number of new pests, many of them found on fir Christmas trees. The original manual had a strong emphasis on Scotch pine. Most of the original pest descriptions remain in the manual; however, given that Christmas tree growers are growing more fir and other species, new pest problems needed to be addressed. The manual is written in everyday language so that anyone with an interest in Christmas trees can read and understand it. This resource is meant to be a tool and not a textbook. Therefore, only the basic information that you need to know to diagnose and manage pest problems in your plantations. In addition to the illustrated pest profiles, you will find practical advice on: * How to look for and recognizepotential pests * How to select, plant, and care for trees so they are less likely to be damaged by pests * How to keep pests at low levels to prevent tree damage The management techniques provided in this book will discourage pests and prevent them from causing serious damage. We encourage you to read the introductory section of the manual to become familiar with the kinds of potential pests that can affect your trees.
