Abstract

Surfactants can improve postemergence herbicide efficacy and reduce the amount of herbicide required to obtain weed control.The effect of surfactants on the efficacy of herbicides is complicated and depends on the interaction among the plant, surfactant, and herbicide.The effects of surfactants on the efficacy of clodinafop-propargyl and/or tribenuron-methyl on wild oat (Avena ludoviciana) and wild mustard (Sinapis arvensis) under greenhouse conditions were investigated. In addition, the surface tension of aqueous solutions of the surfactants and surfactants + herbicides was determined. Significantly lower surface tension values were obtained with the aqueous solutions of citofrigate (Citogate plus Frigate) alone and with the herbicides used in this study.The citofrigate surfactant lead to the greatest enhancement of clodinafop-propargyl and/or tribenuron-methyl efficacy and the effect was species-dependent. The efficacy of clodinafop-propargyl and/or tribenuron-methyl in the presence of surfactants in controlling wild oat was higher than for wild mustard.The foliar activity of the tested herbicides rose with increasing surfactant concentrations.The tank mixture of clodinafop-propargyl and tribenuronmethyl showed a synergistic effect in controlling wild oat and wild mustard.The synergistic effect in controlling wild mustard was greater than for wild oat.
