Book Description
The book deals quantitatively with the generation, dispersion, and deposition of pesticide droplets on vegetation and with off-target drift of undeposited droplets. A computer simulation model of calculating dispersion, deposition, and drift is described with comparisons between calculated results and field measurement results. The model includes the effects of aircraft vortex, atmospheric turbulence, droplet evaporation, and droplet deposition on foliage. Model output includes values of droplet deposit density and size on foliage and ground as well as droplet concentration and size in the drift cloud. In addition, a detailed description of droplet atomizer characterization methods is presented along with a large number of atomizer spectrum results for atomizers in current use. An analysis of a number of forestry spraying innovations is presented. This text is an essential tool in assessing the efficacy and environmental impact of proposed and actual forest spray operations.

Book Description
Introduced to the technical aspects of forestry aerial spraying in the mid-1970's, we were immediately impressed by the complexity of the process of delivering pesticide to foliage. At that time, there was a vigorous public debate in New Brunswick about the ecological and public h~alth impacts of the annual spray program for the control of defoliation of spruce and fir trees by the spruce budworm. The forest industry is important to the province and changes to the established procedures of budworm control could have major economic implications. A rational debate required reliable information about the mechanics of the spraying process. There was a need to supply missing information as to required pesticide application rates, atomizer performance, off-target drift and deposit, and the effects of weather and aircraft operating factors. We were invited to initiate a research program in this domain by New Brunswick forest management officials, and what follows in this book is a logical and quantitative description of the overall process based on our own research and that of others over the intervening years. After a short introduction to aerial spraying, we begin (Chapter 2) by describing forest stands in terms of their interaction with suspended atmospheric particulate material carried along by the wind and susceptible to deposition on foliage. We introduce foliage simulators and their use in measuring the deposit of sprayed pesticide on foliage, the "biological interface" between pest and pesticide.

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
A Bitter Fog is the true story of people fighting to protect their families and homes from Agent Orange and other poisons sprayed on them from the air. This books is about ordinary people who defied profiteering corporations and indifferent government agencies. Meticulous research exposes deception and outright fraud by chemical companies to keep profiting from herbicides they knew were toxic and government complicity in covering up severe human health problems and environmental damage.The award-winning PBS documentary film The People vs. Agent Orange is based in large part on material first revealed in A Bitter Fog. It was awarded the Christopher Award, which is presented to writers whose works "affirm the highest values of the human spirit."This new edition of A Bitter Fog adds a brief update on the fight for environmental justice and numerous photographs that add a new perspective to the story.
