Plant growth regulators can play a role in reducing damage . For this purpose, in shahid Bahonar University research greenhouse two experiment was carried out in 1391. The first experiment in a completely randomized design includes selective herbicides in five level, haloxyfop (0, 3, 4, 5 and 10 per thousand), oxyfluorfen (0, 3, 4, 5 and 10 per thousand) and sethoxydim (0, 6, 8, 10 and 15 per thousand) with three replications . The second experiment was factorial in a completely randomized design with growth regulators and herbicides . Regulators include salicylic acid ( 0, 0.25 and 5.0 mM) , methyl jasmonate (0, 5 and 10 µM) and brassinosteroid (0, 1 and 2 µM) as seed soaking and spray of Herbicides with low concentrations (3 and 4 haloxyfop and oxyfluorfen 6 and 8 sethoxidim) and high concentration (5 haloxyfop and oxyfluorfen and10 sethoxydim) were selected . The results showed that in the first experiment haloxyfop and oxyfluorfen to concentration of 4 and sethoxydim to 8 on growth, biomass, photosynthetic pigments, ion leakage , oxidative enzymes had no harmful effect . In the second experiment it was revealed high concentrations of herbicides significantly reduced the growth characteristics. The combination of regulators and herbicides significantly reduced the negative effects of herbicide.according to results , Salicylic acid 0.25 mM, methyl jasmonate1 µM and brassinosteroid5 µM were more effective.
