Rational Pesticide Use


Book Description

There is growing concern among scientists, farmers and the general public that pesticides are being applied ever more widely but with less and less discretion. This book brings together a range of experts to discuss how crop protection chemicals can be used more rationally, so as to maximise benefits in yield and quality while minimising environmental and economic costs. The book is based on the ninth Long Ashton Symposium and is organised into four sections. The first, environment, examines to what extent current pesticide use is affecting the environment and human welfare, and what changes in practice are justified. The second, application, assesses progress in performance and safety in the use of pesticides, while the next section, resistance, looks at problems and shortcomings arising from the appearance of resistant strains of pests, and considers strategies for surmounting these difficulties. The final section, forecast and pest management, asks whether existing methods of assessing risks are acceptable and seeks ways of rending decision making in crop protection more rational.




Weed and Crop Resistance to Herbicides


Book Description

In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.










Weed Management for Developing Countries


Book Description




Ecological Management of Agricultural Weeds


Book Description

This book presents principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.




Molecular Genetics of Drug Resistance


Book Description

"Molecular Genetics of Drug Resistance" forms a vital and timely review of the genetic processes behind drug resistance. Starting with an overview of the area, each chapter focuses on a particular target with important sections on drug resistance in malaria and in cancer.




Molecular Genetics of Drug Resistance


Book Description

Drug resistance is a growing problem in today's society. Successful drugs are constantly being developed but there is always the risk that a small percent of the drug's target will be immune. These survivors can then lead to a new population, resistant to the action of this drug. New drugs are continuously under development to combat this problem, but these can, in turn, lead to new resistant populations. This problem is universal whether the target is to destroy a deadly virus, or an insect which is ravaging crop production. Development of new drugs is difficult and time consuming so it is of crucial importance that we understand the processes behind drug resistance. "Molecular Genetics of Drug Resistance" forms a vital and timely review of the genetic processes behind drug resistance. Starting with an overview of the area, each chapter focuses on a particular target with important sections on drug resistance in malaria and in cancer. Each chapter has been written by an acknowledged expert in the field and the careful work of the editors has ensured a consistent approach and presentation.




Herbicide Resistance in Plants


Book Description

The late 1980s saw an explosion in the amount and diversity of herbicide resistance, posing a threat to crop production in many countries. The rapid escalation in herbicide resistance worldwide and in the understanding of resistance at the population, biochemical, and molecular level is the focus of this timely book. Leading researchers from North America, Australia, and Western Europe present lucid reviews that consider the population dynamics and genetics, biochemistry, and agro-ecology of resistance. Resistance to various herbicides is discussed in detail, as well as the mechanisms responsible for cross resistance and multiple resistance. This reference is invaluable to those interested in evolution and the ability of species to overcome severe environmental stress.
