Mehmeti, A., Z. Pacanoski, R. Fetahaj, A. Kika and B. Kabashi, 2018. Weed control in wheat with post-emergence herbicides. Bulg. J. Agric. Sci., 24 (1): 74–79
A fi eld study was carried out during the 2011-12 to identify weed species and to investigate the effi cacy of post-emergence herbicides on weeds and their effect on wheat grain yield in the region of Podujeva (north-east part of Kosovo). Four different herbicides were applied at the post-emergence stage of wheat, namely Lintur 70 WG (a.i. triasulfuron + dicamba), Granstar 75 WG (a.i. tribenuron-methyl), Mustang (a.i. fl orasulam + 2,4-D-EHE-ethyl-hepthyl ester) and herbicide combination Sekator OD (a.i. iodosulfuron-methyl Na + amidosulfuron + safener mefenpyr-diethyl) + Furore Super (a.i. fenoxaprop-p-ethyl) in the wheat cultivar Evropa. A total number of 16 weed species was documented in the wheat crop. The highest number of individuals was recorded for Convolvulus arvensis (24.0 plants/m2), Consolida regalis (15.5 plants/m2), Polygonum aviculare (11.5 plants/m2), and Galium aparine (9.8 plants/m2). The most effi cient herbicides proved to be combination iodosulfuron-methyl Na + amidosulfuron + safener mefenpyr-diethyl + fenoxaprop-p-ethyl (83.0%), triasulfuron + dicamba (75.4%), tribenuron methyl (65.6 %), and fl orasulam + 2,4-D-EHE-ethyl-hepthyl ester (64.6%) was markedly lower. Based on the results presented, it is recommended the use of triasulfuron + dicamba or herbicide combination iodosulfuron-methyl Na + amidosulfuron + safener mefenpyr-diethyl + fenoxaprop-p-ethyl in the study region for successful weed control and high wheat grain yields.
