Introduction -- The weedy rice problem -- Diversity of weedy rice populations -- Seed shattering and dormancy in weedy rices -- Vigour and competitiveness of weedy rices -- Ecological relationships -- Strategies for controlling weedy rices -- Examples of weedy rice control campaigns -- Conclusions.
This publication presents a compilation of information from literature reviews on the body of knowledge available from ongoing unpublished research, research reports and symposia carried out on various aspects of the importance, ecology, biology and control of weedy rices (defined broadly and generically as plants of the genus Oryza that infest and compete with rice and other crops--of these, red rice is the dominant and most damaging type). It also highlights global economic and environmental problems created by weedy rices, including red rice types. This document is a result of FAO partnership arrangements with institutions of excellence to generate information that will be for general public use in an attempt to fulfill the goal of food security. Since this subject is of interest a wide range of stakeholders - policy-makers, scientists, technicians and producers - including those interested in rice crop research, production, rice milling for commerce, quarantine regulations a
nd seed trade, an attempt has been made to define weedy, wild and red rice so as to engender a common understanding of various aspects of this group of pests. The information provided will contribute to the better knowledge of weedy rices throughout the world.--Publisher's description.
