Book Description
Herbicides were tested on 16 common shrubs and weed trees during the past 24 years. The woody plants included snowbrush ceanothus, deerbrush ceanothus, mountain whitethorn, varnishleaf ceanothus, sprouting and nonsprouting forms of greenleaf manzanita, hairy manzanita, hoary manzanita, golden chinkapin, golden evergreenchinkapin, Saskatoon serviceberry, Pacific madrone, salmonberry, western thimbleberry, scrub tanoak, and canyon live oak. Chemicals tested included 2,4-D, dichlorprop, 2,4,5-T, silvex, 2,4-DB, amitrole, amitrole-T, 2,3,6-TBA, AMS, picloram, KreniteTM, triclopyr, and an experimental carbamate compound. Low volatile esters of 2,4-D and 2,4,5-T proved the most effective and versatile herbicides for silvicultural use in western Oregon. Results of the screening tests are related to comparable data from small plot tests and project-scale aerial spray trials. To aid silviculturists, useful treatments and the most effective herbicide are shown in bold-face type for each shrub and weed tree.

Book Description
Weed Management Handbook updates the 8th edition of Weed Control Handbook (1990). The change in the title and contents of the book from previous editions reflects both the current emphasis on producing crops in a sustainable and environmentally-friendly manner, and the new weed management challenges presenting themselves. This landmark publication contains cutting edge chapters, each written by acknowledged experts in their fields and carefully drawn together and edited by Professor Robert Naylor, known and respected world-wide for his knowledge of the area. The sequence of chapters included reflects a progression from the biology of weeds, through the underpinning science and technology relating to weed management techniques including herbicides and their application to crops, leading to principles of weed management techniques. Finally a set of relevant case studies describes the main management options available and addresses the challenges of reduced chemical options in many crops. Weed Management Handbook is a vital tool for all those involved in the crop protection / agrochemical industry, including business managers, horticultural and agricultural scientists, plant physiologists, botanists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying horticultural and agricultural sciences, plant physiology, botany and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Weed Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Publishing.

Book Description
After a brief description of silvicultural problems, the author tells how to prescribe herbicidal sprays for aerial, application in Pacific Northwest forests. The publication offers a detailed discussion of the five basic considerations: (1) selection of the best herbicide or herbicides, (2) amount of herbicide to be applied per acre, (3) carriers, (4) volume of spray per acre, and (5) seasons for application of aerial sprays. Appendixes provide standard treatments for many common silvicultural problems in site preparation and to release young conifers from shrub and weed tree competition. Also included is a glossary of agricultural chemical terms and a list of abbreviations used in brush control literature. This is a working manual for silviculturists based upon more than 20 years research and experience of Federal, State, and industrial foresters. It provides much information not generally available in the literature and tells how to use this knowledge in Pacific Northwest silviculture. Although designed primarily for the Pacific Northwest, the basic information should be useful in culture of coniferous forests far outside this region.
