- Abstract
Field trials were conducted in 2009 and 2010 to evaluate herbicides and their combination for weed control in carrots production regions in the Republic of Macedonia. The weed population in the both years was consisted of annual spring and summer ones, and some perennial weeds. The weediness in the both years was relatively high (129.6 plants/m2 in 2009 and 172.7 plants/m2 in 2010, respectively). The most dominant weeds were Portulaca oleracea and Echinochloa crus-galli in 2009 and Polygonum lapathifolium, Portulaca oleracea and Echinochloa crus-galli in 2010. Efficacy of herbicides in control of weeds was ranged of 69.8% (metolachlor PRE + linuron POST) to 98.2% (metolachlor + prometryn applied PRE) in 2009, and 71.2% (metolachlor PRE + linuron POST) to 96.8% (metolachlor + linuron applied PRE) in 2010, respectively. Efficacy of herbicides in the control of prevailing weeds during the 2-year field trial period was ranged from 54% to 100%. Particularly high efficacy showed both combinations metolachlor + prometryn and metolachlor + linuron applied PRE which provided nearly 100% control. All applied herbicides and their combinations showed high selectivity to carrots, no visual injured were determined by any rates in both year. Crop yields treated by herbicides reflected their efficiencies in weed control. The highest carrots yield in both years (34925 and 35395 kg/ha, and 32865 and 34254 kg/ha, respestively) were recorded in plots treated with metolachlor + linuron and metolachlor + prometryn applied PRE.
