Weeds are the cause of great losses to crop production in the tropics and grassy weeds present a particular problem because of their similarity to cereal crop plants. It is therefore difficult to devise control methods and management practices appropriate for such weeds. This book reviews our current knowledge of this subject and is the outcome of a workshop on integrated control of grassy weeds in tropical subsistence farming systems, held in Nairobi in February 1990. The workshop was organised by CASAFA (Commission on the Application of Science to Agriculture, Forestry and Aquaculture) of the International Council of Scientific Unions. The contents include a general review of grassy weeds, their physiology in tropical agriculture, management by biological and chemical control, integrated weed management, control in tropical cereals, in tropical grasslands and forage crops, in mixed crops and in upland rice, and overviews of grassy weeds in Kenya, the Phillipines and Australia.

This book introduces the most recent research findings on selected parasitic weeds that occur in Jordan and are also spread in Middle Eastern countries. It is a valuable source of information for researchers, students as well as farmers, giving readers a better understanding of these regional parasites and their unusual growth patterns. The book set consists of two volumes. The first volume includes information about genera which are typically known as root parasites. These genera are Orobanchaceae, Santalaceae, and Cynomoriaceae families. The second volume covers stem parasites of the Cuscutaceae, Loranthaceae and Viscaceae families. The detailed information presented in this set makes this an essential reference on weeds and parasitic plants in Jordan and Middle Eastern regions. Key Features: - Chapters cover the biology, ecology, distribution, economic significance, host ranges, and control methods of a variety of regional weeds in an organized way - It includes information on parasitic families, genera and species that are found in Jordanian flora and their hosts. - It also provides coloured photos of weeds - Presents the latest techniques for plant pest management - Provides references for further reading - Includes a glossary and appendix suitable for beginners Audience: Botanists, farmers, researchers in the field of agriculture and agronomics, with an interest in the flora of Jordan and the Middle East.
