Abstract
En este trabajo se presentan los resultados del seguimiento de parcelas con
elevada infestación de la mala hierba invasora Zea mays spp. mexicana ad. int. (teosinte) en
las que se han sembrado cultivos diferentes al maíz para poder controlar mejor esta especie.
Se han visitado 13 parcelas desde junio 2015 hasta septiembre 2016. La mayoría de parcelas
fueron sembradas con alfalfa en junio 2015 después de cultivar cebada o bien en septiembre
tras guisante. Se observa una rápida reducción en el número de plantas de teosinte
emergidas en el tiempo especialmente al incluir guisante en la rotación y no se observan
plantas adultas dentro de la alfalfa, al ser eliminadas con las siegas. No obstante, preocupa
la presencia de individuos junto a estructuras de riego y en márgenes, que no siempre son
eliminados, por lo que hay que extremar las precauciones para evitar la resiembra.
This work describes the changes observed in emergence of the invasive weed Zea mays spp. mexicana ad. int. (teosinte) in plots sown with other crops than maize to better control this species. 13 plots have been visited from June 2015 to September 2016. Most of the plots were sown with alfalfa in June 2015 after cropping barley or in September after peas. A fast reduction in the emergence of teosinte plants has been observed in time especially when peas were included in the rotation and no adult plants were detected inside the alfalfa crop as they are eliminated by mowing. However, the presence of individual plants next to irrigation structures and in field edges which are not always eliminated are a concern and preventive measures need to be taken to avoid re-sowing of the weed.
