From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.

Studies in the Agricultural and Food Sciences: Plant Breeding for Pest and Disease Resistance presents a critical review of the development of resistant varieties of plant to pests and diseases. It discusses the economic impact of pests and diseases; the methods of controlling these pests and diseases; and the challenges being faced by a plant breeder. Some of the topics covered in the book are the general principles and methods of breeding for resistance; importance of parasite variability to the plant breeder; methods of testing for resistance; requirements for successful inoculation; production of resistant varieties; and economic importance of fungal diseases; and variability in fungal pathogen. Pathogenic fungi and fungal diseases are also covered. The control of fungal diseases by resistant varieties is discussed. An in-depth analysis of diseases in plants is provided. The characteristics of bacteria and bacterial diseases are also presented. A chapter is devoted to epidemiology of diseases associated with mycoplasma-like organisms and rickettsia-like organisms. The book can provide useful information to farmers, botanists, students, and researchers.

This book reviews and synthesizes the recent advances in exploiting host plant resistance to insects, highlighting the role of molecular techniques in breeding insect resistant crops. It also provides an overview of the fascinating field of insect-plant relationships, which is fundamental to the study of host-plant resistance to insects. Further, it discusses the conventional and molecular techniques utilized/useful in breeding for resistance to insect-pests including back-cross breeding, modified population improvement methods for insect resistance, marker-assisted backcrossing to expedite the breeding process, identification and validation of new insect-resistance genes and their potential for utilization, genomics, metabolomics, transgenesis and RNAi. Lastly, it analyzes the successes, limitations and prospects for the development of insect-resistant cultivars of rice, maize, sorghum and millet, cotton, rapeseed, legumes and fruit crops, and highlights strategies for management of insect biotypes that limit the success and durability of insect-resistant cultivators in the field. Arthropod pests act as major constraints in the agro-ecosystem. It has been estimated that arthropod pests may be destroying around one-fifth of the global agricultural production/potential production every year. Further, the losses are considerably higher in the developing tropics of Asia and Africa, which are already battling severe food shortage. Integrated pest management (IPM) has emerged as the dominant paradigm for minimizing damage by the insects and non-insect pests over the last 50 years. Pest resistant cultivars represent one of the most environmentally benign, economically viable and ecologically sustainable options for utilization in IPM programs. Hundreds of insect-resistant cultivars of rice, wheat, maize, sorghum, cotton, sugarcane and other crops have been developed worldwide and are extensively grown for increasing and/or stabilizing crop productivity. The annual economic value of arthropod resistance genes developed in global agriculture has been estimated to be greater than US$ 2 billion Despite the impressive achievements and even greater potential in minimizing pest- related losses, only a handful of books have been published on the topic of host-plant resistance to insects. This book fills this wide gap in the literature on breeding insect- resistant crops. It is aimed at plant breeders, entomologists, plant biotechnologists and IPM experts, as well as those working on sustainable agriculture and food security.

The annual joint meeting of experts from the Food and Agriculture Organisation and the World Health Organisation was held in September 2001. This purpose of this meeting was to: review data analysis methods for estimating the maximum residue levels arising from pesticide use according to good agricultural practices; and review toxicological and related data for estimating acceptable daily intakes (ADIs) of pesticides for human health. This report presents information on ADIs of a number of pesticides, maximum residue levels, and general principles for the evaluation of pesticides. It provides summaries of the toxicological evaluations of pesticide residues in food, together with the recommendations made by the joint meeting.
