One of the reasons frequently given for large family size in traditional societies in developing countries is that it provices labour for crop production. In the tropics people spend more time removing weeds than in any other part of the world. In these areas weed control is inextricably linked with the drudgery that characterises peasant agriculture, and it is argued that the task of removing weeds occupies a disproportionate percentage of the population, thereby preventing these countries from developing in other areas of their economies. Against this background it is perhaps surprising that weeds are without doubt the most underrated of pests in the tropics and their control is often severely hampered by the lack of resources, appropriate expertise and, in many cases, determination. Weed Science in the Tropics is a practical book aimed at anyone who is actually concerned with controlling these competitive plants on an everyday basis. It was written by Dr Okezie Akobundu of the International Institute of Tropical Agriculture in Ibadan, who believes that it will be of particular use to teachers, agricultural students and consultants as well as those who are involved directly. The book seeks to introduce a new dimension into the teaching of the subject by placing weed science as an integral part of a crop protection programme - a point emphasised by the first chapter which is specifically devoted to this subject. Further into the book, six full chapters are devoted exclusively to herbicides, covering their chemistry, presence in the environment, their action in plants and the soil, and their safe and efficient use. This is justified, according to the author, by the fact that herbicides are relatively new to tropical agriculture and in general are poorly understood. Despite the fact that the book offers a detailed guide to all aspects of weed biology and control, it has deliberately been written in such a way that those who require only a short introduction to the subject may focus on a restricted number of chapters, while more advanced students can find considerably more detail in other sections. The appendices list common and trade names of herbicides together with their manufacturers and information on mammalian toxicity and residue tolerance. Akobundu. I O, 1987.
