Evaluation of Individual and Tank-mix Application of Herbicides on weed and Saffron Corm Weight in Neyshabour

To evaluate the impacts of individual and tank-mix application of common herbicides on weed control as well as saffron corm an experiment with nine treatments and three replications was conducted in a saffron field in Neyshabour. The treatment included herbicides such as Oxyfluorfen 1.5 l. ha-1, Ioxynil 2 l. ha-1, Metribuzin 750 g. ha-1, Sethoxydim 2 l. ha-1, Fluazifop-P-Butyl 2.5 l. ha-1, Haloxyfop-R-methyl 1.3 l. ha-1, Oxyfluorfen+Haloxyfop-R-methyl, Ioxynil+Haloxyfop-R-methyl and Metribuzin+haloxyfop-R-methyl. Orthogonal comparisons showed that tank-mix application could significantly reduce weeds dry matter in comparison with individual application of their components. Compared with Ioxynil+Haloxyfob-R-metyl, tank mix application of Haloxyfop-R-methly with Oxyfluorfen or Metribuzin could significantly reduce weeds’ dry matter. Sethoxydim had the least effect on weed dry matters. The maximum weight of saffron corms were observed in treatments including Oxyfluorfen+Haloxyfop-R-methyl, Ioxynil+Haloxyfop-R-methyl, and Metribuzin+Haloxyfop-R-methyl.
