The damaging effects of weed competition are often underestimated in developing countries, perhaps because unlike insects and diseases, they often cause few obvious symptoms of damage prior to harvest. Also the weeds seem to grow elsewhere, and have always done so, without causing anv harm. Yet in Africa alone weeds are known to cause average crop losses of at least 30%. These are serious losses by any standards but all the more so when there are hungry mouths to feed. Such losses have wide ranging effects from limiting income from cash crops (and hence foreign exchange) to contributing directly to the poverty of small-scale farmers. Common Weeds of East Africa is an FAO publication produced as a result of the meeting of an FAO panel of experts on Improved Weed Management, held in Nairobi in April 1984. The text provides a clear and concise description in both English and Swahili of each of 63 weeds selected because they are common or serious pests in one if not all three countries of Kenya, Tanzania and Uganda. Each description is accompanied by a colour photograph of the weeds' flowers while line drawings are used to demonstrate other diagnostic features such as leaf shape. A range of common names is given where appropriate and a glossary is provided to explain terms used in the text. Finally a bibliography suggests sources of information on weed biology, distribution and control so that further action may be taken once the weed has been identified. The book fits in a large pocket, making it easy to carry in the field, while its clear pictures, text and diagrams should considerably improve the ease with which troublesome weeds may be identified and subsequently control led.
