Response of Sorghum halepense demographic processes to plant density and rimsulfuron dose in maize

In spatially heterogeneous weed infestations, variable dose technologies could be used to minimise herbicide use; high doses could be applied to reduce high-density patches and low doses to maintain weed populations in low-density portions of a field. To assess the potential short- and long-term eff...

To assess the potential short- and long-term effects of variable herbicide dose and site-specific management, the major weed demographic processes were described and parameterised in this study. Various doses of rimsulfuron (from 0 to 12.5 g a.i. ha 1 ) were applied to different densities of Sorghum halepense (0–100 plants m 2 ). Contrary to similar studies with other weed species, higher herbicide efficacy was not observed at low densities, suggesting that the same rimsulfuron dose should be applied regardless of the S. halepense density. The highest percentage of control was obtained with the full rimsulfuron dose. However, it did not guarantee a decrease of the infestation in the following season in the field areas where the initial S. halepense density was lower than 60 plants m 2 . Reduced doses of rimsulfuron to control S. halepense cannot be recommended based on our results.This research was funded by the Spanish CSIC (JAEDoc contract to Judit Barroso), by a Fulbright Scholarship (granted to Judit Barroso) in co-operation with the UPM (University Polytechnic of Madrid) and the MSU (Montana State University) and by the Spanish CICyT (project AGL 2008-04670-C03).Peer reviewedJohn Wiley & SonsComisión Interministerial de Ciencia y Tecnología, CICYT (España)Universidad Politécnica de MadridConsejo Superior de Investigaciones Científicas (España)Barroso, Judit [0000-0001-7071-5341]Maxwell, Bruce D.Dorado, José [ 0000-0002-2268-2562]Andújar, Dionisio [0000-0002-5801-0944]San Martin, Carolina [0000-0001-6273-2301]Fernández Quintanilla, César [0000-0002-2886-9176]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242016info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/375191reponame:DIGITAL.CSIC.
