Two field experiments were conducted on the fields of the Faculty of Agriculture, Karbala University, Iraq, during the winter season 2015-2016 and 2016-2017 to evaluation of magnetic treatment of herbicide spraying solutions to increase activity of weed control with five cultivars of wheat. The results showed the significant effect of magnetic herbicide solution at increasing the efficiency of herbicide absorption by weed and decreasing its density and biomass per m. Weed control percentage when the use of half recommendation for the herbicide under magnetic solution has exceeded the use of the full recommendation without a magnetization. Response of cultivars to herbicide spraying treatments according to the different susceptibility of the weeds competition to the different growth season. The weed control treatment were correlation with the grain yield of the wheat crop as a strongly negative (r2 = 0.98 and r2 = 0.97 for the first and second seasons respectively) and for all the weed control treatment. Liner regression model for the first season showed an increase in the density of weed, one plant on the square meter causes decrease in cereal yield by 76kg per h. In the second season, by 70kg per h, it is concluded that the use of the magnetization of solution spray for half herbicide amount may give an increase on the amount 518kg per h for the first season and by 538kg per h for the second season against the same treatment without magnetization.
