Evaluation of Maister power OD a New Herbicide in Controlling Weeds of Corn in Moghan region

In order to study the Evaluation of idosulfuron metal sodium+ foramsulfuron metal+ thincarbazone metal+ saiprosulfamed (Maister power OD) in weeds control of corn fields, an experiment was conducted in a randomized block design with 12 treatments and 4 replications in Moghan region, Iran, in 2014. The most important weeds were black night shade (Solanum nigrum L.), lambs quarters (Chenopodium album L.) and barnyard grass (Echinochloa crus-galli L.). The results showed that the density and dry weight (biomass) of weeds were affected by the herbicide treatments So that weeds dry weight highest treatments show in idosulfuron metal sodium+ foramsulfuron metal+ thincarbazone metal+ saiprosulfamed (Maister power OD) 1, 1.25, 1.5 L.ha-1 and Nicosulfuron Bromoxynil + MCPA (Kroz +Bromicide) 1.5 L.ha-1. Also Nicosulfuron Bromoxynil + MCPA (Kroz +Bromicide) 1.5 L.ha-1 and idosulfuron metal sodium+ foramsulfuron metal+ thincarbazone metal+ saiprosulfamed (Maister power OD)1.25-1.5 L.ha-1 Treatments showed the highest yield percentage and lowest yield with 12.5 percentage The hand weeding and Nicosulfuron (Kroz) 2 L.ha-1 with 46.4 percentage. Totally, The best herbicides were foramsulfuron + iodosulfuron + thincarbazone (Maister power OD) 1-1.5 L.ha-1 and foramsulfuron + iodosulfuron + thincarbazone (Maister power OD) 1.25 L.ha-1 + citogate with more than 85% efficacy in weed control. Corresponding to the good efficacy, Maister power OD 1 L.ha-1 for post-emergence at the 5-2 leaf weeds were suitable for application in corn.
