Avena fatua L.

Abstract

Avena fatua L. is an annual cicle grass native to the eastern Mediterranean. The seeds exhibit dormancy. Seedlings emerge during autumn-sinter, a process that can extend into early spring. It is a species with protoperiodic response (quantitative long day), while the time to flowering is controlled by photo-period and temperature. The presence of this species is reported in almost all parts of teh world where sinter-cereal crops are grown, including winter cereal production systems. Particularly in the south of the Province of Buenos Aires, its presence has been registered in uo to 80% of fields cultivated with barley. It can cause considerable losses of crop yields, which are increased by the cost of cleaning the sedes of the cereal, particularly in the case of malting industry. Avena Fatua is more fertile and its seeds are shed before harvest in the environment of wheat crops compared to berley, even with applications of herbicides. The most commonly used practice for control in wheat and barley crops is the application of postemergence herbicides. A biotype resistant to clodinafop-propargyl, diclofop methyl and fenoxa-prop-p-ethyl has been registered in southwest of Buenos Aires. Beyond the successful results that can be achieved by the application of herbicides, it must be considered that the selection pressure that these exert in favor of the selection of resistant biotypes, is an unforable consequence of its misuse.

La Avena fatua L. es una maleza relevante en sistemas de producción de cereales de invierno, particularmente en el Sur de la Provincia de Buenos Aires, no sólo por las pérdidas de rendimiento y los costos para su control, sino también por los descuentos que se generan en la comercialización, particularmente en lotes de cebada destinados a la industria maltera. En el presente capítulo se abordan aspectos propios de su taxonomía y caracterización botánica, distribución geográfica e incidencia en diferentes sistemas de producción, su biología, fenología, dinámica de emergencia y dinámica poblacional. Se mencionan características particulares de efectos ambientales en la dormición de las semillas y bases aplicadas para la elaboración de modelos de predicción de emergencia. En cuanto a dinámica poblacional, se presentan resultados de diferentes estudios realizados en el sudoeste de Buenos Aires, evaluando los efectos de diferentes prácticas agronómicas en los distintos procesos demográficos, sobre lo cual no se disponía de antecedentes en Argentina. También se describen aspectos propios de la aplicación de herbicidas a lo largo de los últimos 40 años, considerando los riesgos que su reiterada aplicación genera en términos de selección de biotipos resistentes.
