| description | Red rice in Colombia: Performance and risks The types of red rice (Oryza sativa L.) found in rice fields in Colombia are described, as well as their performance and the main practices contributing to their dissemination. Several control measures are proposed. In many countries red rice is one of the most aggressive weeds affecting cultivated rice, causing significant yield losses, affecting grain quality, and increasing production costs. Studies conducted on this type of rice indicate that several practices promoting its dissemination include monocropping, planting of noncertified seed, use of machinery contaminated with the weed’s seed, and inadequate management due to lack of understanding of red rice biology and performance. In several countries, such as Colombia, other factors escalate the problem of red rice: the size of rice fields (most < 10 ha), soil management practices applied by land tenants who are only concerned about their harvest, and deficient professional and technical assistance (> 50% of the rice fields are managed without professional assistance). |

Se describen los tipos de arroz rojo (Oryza sativa L.) presentes en los arrozales de Colombia, su comportamiento, las principales prácticas que contribuyen a su diseminación, y se proponen algunas medidas de control. El arroz rojo es, en muchos países, una de las malezas más agresivas del arroz cultivado porque reduce su rendimiento, desmejora la calidad de su grano y aumenta los costos de su producción. Según estudios realizados con este tipo de arroz, algunas de las prácticas que favorecen su diseminación incluyen: el monocultivo, la siembra de semilla no certificada, el uso de maquinaria contaminada con semillas de la maleza, y el manejo inadecuado que se le da por el desconocimiento de su biología y de su comportamiento. En algunos países como Colombia, otros factores que agravan el problema del arroz rojo tienen que ver con el tamaño de las unidades productoras de arroz (en su mayoría < 10 ha), la administración de la tierra, que está en manos de arrendatarios preocupados únicamente por la cosecha, y la deficiente asistencia técnica profesional (> 50% de las unidades productoras sin manejo profesional). 2010 2017-06-20T09:02:32Z 2017-06-20T09:02:32Z Book Chapter https://hdl.handle.net/10568/82515 es Open Access application/pdf International Center for Tropical Agriculture Clavijo, Jairo; Montealegre, Fabio. 2010.
