Botany & plant sciencesJune 2000Hemp Diseases and Pests
Management and Biological Control
by John M McPartland, Robert C Clarke, David P Watson
Hemp is enjoying a worldwide resurgence. This unique book combines a review of the hemp pest and disease literature published over the past 50 years with up-to-date information on modern biological control techniques. Each pest and disease organism is presented in the same format, covering economic impact, geographical and host-plant range, plant symptoms, taxonomic description, life history, and differential diagnosis. Important cultural, mechanical, biological and chemical controls are highlighted with charts, illustrations and explicit instructions. Easy-to-use keys are included for rapid identification of the most common pests. Introductory chapters describe the general principles of plant protection, requirements for healthy plant growth, and taxonomy of parasites and pathogens.

Insecticide & herbicide technologyJuly 2000Priorities in Biopesticide Research and Development in Developing Countries
by Jeremy Harris, David R Dent
Biopesticides Series, No. 2Biological pesticides based on pathogenic micro-organisms specific to a target pest offer an ecologically-sound and effective solution to pest problems. They pose less threat to the environment and to human health than do chemical pesticides. However, despite the enormous potential for biopesticides, their development, commercialisation and use has been slow.The information reported in this book is based on a survey of more than 100 biopesticide research workers in developing countries. The results demonstrate that the main difficulties and constraints facing researchers relate to a lack of expertise in the crucial later stages of development. Biopesticide research is receiving mostly low investment, mainly from the public sector, and requires more multidisciplinary expertise. It is concluded that targeted assistance on a multinational and multi-disciplinary basis is required in developing countries in order to remove the constraints.

Limnology (freshwater)April 2005Irrigation and Drainage Performance Assessment
Practical Guidelines
by Marinus G Bos, Martin Burton, David J Molden
Effective irrigation and drainage systems are essential if growing demands for water resources are to be met. For the use of water for irrigation to be improved we must understand current levels of performance. This book draws together the growing body of knowledge on irrigation and drainage performance assessment that has been gained over the last twenty years. It provides guidelines for practitioners to enable them to design and carry out performance assessment and implement performance-based management. Developed by a working group of the International Commission on Irrigation and Drainage (ICID) it provides a generic framework for performance assessment with guidance on the theory and practice of how to audit and assess the performance of irrigation and drainage schemes.
