Abstract
This experiment was conducted in 2002 and 2003 to evaluate the effects of chloridazon and desmedipham mixture plus a nonionic surfactant on weeds of sugar beet at Safi Abad agricultural research center of Dezful, Iran. The experimental design was a randomized complete block with 12 treatments and three replications. Treatments included postemergence application of the mixture of chloridazon + desmedipham at 3.2 + 0.78, 3.2 + 0.63, 2.4 + 0.63, 4 + 0.47 and 3.2 + 0.47 kg ai ha –1 and aforementioned herbicide treatments each plus a nonionic surfactant (Citowett) at 0.35% (v/v) at the 4- leaf stage of sugar beet, weed free and weedy check. In both years, application of the mixture of the chloridazon + desmedipham treatments each plus surfactant compared to the application of the same treatments without surfactant had 61 and 38% higher efficacy in reducing the total number of broadleaf weeds, respectively. Application of mixture of the chloridazon + desmedipham treatments at the abovementioned rates with and without surfactant provided 91 and 83% of sugar beet root yield, respectively. Weedy check plots had only 50% of sugar beet root yield. Application of the mixture of the chloridazon + desmedipham treatments at the abovementioned rates with and without surfactant provided 93 and 83% of pure sugar yield, respectively, Correspondence to:Ghanbari-Birgani, d.ghanbari@safiabad.ir
