Cultural control of herbicide-resistant Lolium rigidum Gaud. populations in winter cereal in Northeastern Spain

Lolium rigidum Gaud. is one of the most common weed species in winter cereals in Northeastern Spain. Herbicide resistance has been growing since the mid 90's and exclusive herbicide use is not enough in many cases, so that it is necessary to combine as many control tools as possible. Six field...

description Lolium rigidum Gaud. is one of the most common weed species in winter cereals in Northeastern Spain. Herbicide resistance has been growing since the mid 90's and exclusive herbicide use is not enough in many cases, so that it is necessary to combine as many control tools as possible. Six field trials have been conducted during the cropping seasons 2001-02, 2002-03 and 2003-04 on winter cereal infested with herbicide resistant L. rigidum in Northeastern Spain testing different cultural control strategies. Sowing delay was conducted at five fields, mouldboard ploughing at four fields, the combination of sowing delay and ploughing at two fields, increasing the cereal sowing density and combined with sowing delay at one field. Sowing delay was confirmed to have an irregular efficacy depending on the L. rigidum emergence during the delay period. In the trials, weed emergence was reduced up to 88% in the best case but there was no effect in two cases. Ploughing had a more constant efficacy and reduced weed emergence between 50 and 80% although stoniness impeded in one occasion a correct soil inversion causing a very low efficacy. Increasing the cereal sowing rate did not reduce the weed population. The combination of the different methods did not increase significantly the individual efficacy, and one method was clearly more effective than the other, depending on the trial. In fields with high L. rigidum density, these methods are not effective enough and need to be combined with other methods, which are discussed in the text.

La resistencia a herbicidas ha ido aumentando desde mediados de los años 90, haciendo necesaria la combinación de cuantas más técnicas de control sean posibles. Se realizaron seis ensayos de campo desde el año 2001 al 2004 sobre cereal de invierno infestado con L. rigidum resistente a diferentes herbicidas en el nordeste de España, para probar diferentes estrategias de control culturales. Se estudió el retraso de siembra en seis campos, laboreo de vertedera en cuatro campos, la combinación de retraso de siembra y laboreo de vertedera en dos campos, incrementar la densidad de siembra y combinarla con retraso de siembra en un campo. El retraso de siembra tuvo una eficacia irregular dependiendo de la emergencia de L. rigidum durante el período de retraso. Se alcanzó una reducción de la emergencia del 88% en el mejor de los casos, pero no hubo efecto en otros dos campos. El laboreo tuvo una eficacia más constante y redujo la emergencia de la mala hierba entre el 50 y el 80%, aunque la pedregosidad impidió en un caso una correcta labor. Incrementar la dosis de siembra no redujo la población de la mala hierba. La combinación de los diferentes métodos no aumentó de forma significativa el efecto individual y un método fue claramente más efectivo que el otro, dependiendo del ensayo. En campos con densidades elevadas de L. rigidum estos métodos no la reducen de forma suficiente y necesitan ser combinados con otros métodos que son discutidos en el texto.Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya)2009info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://doi.org/10.5424/sjar/2009071-407http://hdl.handle.net/10459.1/41556reponame:Recercat.
