Book Description
The genesis of the International Food Legume Research Conference (IFLRC) can be traced back to 1983 - and so this Volume, the Proceedings of that Conference, has had a gestation period of close to five years. Professor Norman Simmonds, the perennial Book Review Editor of Experimental Agriculture, has expressed the opinion (vol. 22, p. 201, 1986) that "Many symposial volumes are just plain awful!" Elsewhere (Nature vol. 312, pp. 201-2, 1984), Anthony Watkinson - then a Commissioning Editor at Oxford University Press has described several reasons which have led him to believe that "Conference proceedings - symposia - are generally disliked . . . . To put it mildly, this type of publication has a bad name". The problems, from an author's perspective, of contributing to any many-authored publication are aired in an exchange of correspondence in Biologist (vol. 30, pp. 123 and 180, 1983; and vol. 31, pp. 3 and 69,1984). And from the editor's viewpoint, D. J. Weatherall - then Nuffield Professor of Clinical Medicine at the University of Oxford - has described (Nature vol. 317, p.

Book Description
Invasive alien species are a major threat to biodiversity and ecosystems throughout the world. In India, a country with four of the world's most important 'biodiversity hotspots', the invasion of alien plants means risking a national ecological disaster with major social and economic consequences. Currently, there is insufficient information about invasive alien plants; their distribution, rate of spread and adaptability to new environments. This book reveals existing and potential invaders, evaluates the level of risk they pose to native species and suggests steps to manage spread and limit damage. Invaluable to policy-makers, this book is also required reading for researchers of invasive plants worldwide.

Book Description
Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.

Book Description
Rice weeds are listed by rice culture by country. The lists were compiled from a comprehensive review of the literature on rice weeds and their control in 15 South and Southeast Asian countries.
