CIRSIUM ARVENSE (L.) SCOP.: AN UNWANTED PRESENCE IN WINTER WHEAT CROPS PUBLISHEDDan Nicolae Manea, Gheorghe Cârciu, Aurel Lăzureanu, Simion Alda
Research was carried out over two years (2004-2005 and 2005-2006) on the trial field of the Department of Agricultural technology and Weed Science of the Agricultural and Veterinary University of the Banat in Timişoara, Romania, on a slightly salified vertosoil. The trial was mono-factorial. We monitored the efficiency of weed control, in particular of Cirsium arvense (L.) Scop. using ten different post-emergent herbicides. The best results in diminishing weeding degree (over 92.00%) compared to the control treated with the classical product SDMA Super 1 l/ha, concerning both total weeding and horse thistle were the result of applying the herbicide Dialen Super 0.90 l/ha and Premiant 1 l/ha, respectively. On all the trial plots, 30 days after application, and particularly 60 days after application, there was a regeneration trend in horse thistle shoots. All the herbicides we tested were very selective for the winter wheat cultivar we cultivated (Lovrin 49), with no symptoms of phyto-toxicity.
