23149

this study was carried out in 2007 and 2008 in İzmir, Ödemiş – Bozdağ, Ovacık village. In this study control, rimsulfuron 5 g/da (two applications with an interval of 15 days), imazapic 2.5 cc/da (two applications with an interval of 15 days), imazapic 2.5 cc/da (at the second treatment date), glyphosate 2.5 cc/da (two applications with an interval of 15 days), glyphosate 2.5 cc/da (at th second treatment date), glyphosate 5 cc/da (two applications with an interval of 15 days), messenger 30 g/da (1 mounth before the flowering and the harvest) effect of broomrape. The effects of the herbicides were evaluated by means of, broomrape above-ground bough number and it’s fresh and dry weights criteria. The effects of treatments on potato yield was also assessed. For this purpose studies were conducted in both years, according to randomized complete block design with four replications of eight characters. Results of the studies showed that glyphosate at 5 + 5 ml/da dose reduced broomrape number of branches (94.8%, 66.1%), and dry weight (97.8%, 62.2%) in both years. Glyphosate at 2.5+ 2.5 ml / da dose reduced branch number of broomrape (85.2%, 71.5%) and dry weight (91.5%, 65.62%) in both years. While efficacy of imazapic was around 50 % in 2007, it was around by 20 % in 2008. Messenger was ineffective broomrape in both years. Rimsulfuron affected the branches of broomrape by 46.5 % in 2007, but it inreased by 67.6 % in 2008.
