Abstract

To evalate the effects salicylic acid (SA) on corn, weeds, and some herbicide efficiency, a factorial experiment with two factor as randomized complete block (RCB) design with three replications was conducted in the research field of university of Tabriz, Iran in 2015. The first factor was 8 herbicide treatments (Bentason, Nicosulfuron, 2, 4-D + MCPA, Bromoxynil + MCPA, Rimsulfuron, Nicosulfuron + Rimsulfuron, Mesotrion + S-metolacholor + Terbuthlazine, Udosulfuron + Foramsulfuron + Tincarbason), and 2 controls treatments (weed free and weed infest), and the second factor was SA in 2 levels (0 as distilled water, and 1 mM SA). Results showed that SA increased corn leaf area, and leaf and stem dry weights. This increase was outstanding in herbicides that could successfully control weeds. In weed infested treatment, SA increased common lambesquraters (Chenopodium album L. ) densities and dry weights, as the main weed species observed in the field. There, in the presence of weeds, SA is more beneficial for weeds. Nicosulfuron was weak in weed control, and SA application increased weeds density and dry weights. Bromoxynil + MCPA, Mesotrion + S-metolacholor + Terbuthlazine, and 2, 4-D + MCPA were successful herbicides in reduction of weeds density and dry weight, and their efficiency was not reduced in presence of SA. Therefore, in herbicide treatments with weak efficiency in weed control, usage of SA is more beneficial for weeds. According to the results, application of SA is not recommended with low efficiency herbicides in weed control.
