Soltani, N., Shropshire, C. and Sikkema, P. H. 2010. Adjuvant comparison for postemergence weed control in corn. Can. J. Plant Sci. 90: 543-547. Six field trials were conducted over a 2-yr period (2004 and 2005) at Exeter and Ridgetown, ON, Canada, to evaluate the effect of postemergence application of rimsulfuron plus dicamba plus S-metolachlor/benoxacor, nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr and nicosulfuron plus dicamba/diflufenzopyr with and without Agral 90 (R) or Liberate (R) non-ionic surfactants on weed control and yield of corn. There was no difference between Agral 90 (R) and Liberate (R) adjuvant in respect to control of velvetleaf, common ragweed, common lambsquarters and green foxtail. All herbicide treatments provided significantly higher yield than the untreated control. There was also no difference between Agral 90 (R) and Liberate (R) in respect to corn yield when added to rimsulfuron plus dicamba plus S-metolachlor/benoxacor, nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr and nicosulfuron plus dicamba/diflufenzopyr. Based on these results, Liberate (R) can be used as an alternative non-ionic surfactant for Agral 90 (R) with the herbicides evaluated.
