This thesis presents the results of the research aiming at determination of the weed control efficacy of the herbicide Lintur 70 WG (dicamba + triasulfuron) applied alone or in combination with growth regulators Antywylegacz Płynny 675 SL (chlormequat chloride) and Cerone 480 SL (ethephon) under different mineral fertilization conditions in a spring wheat crop. A two-factorial field experiment was conducted at the Czesławice Experimental Farm, belonging to the University of Life Sciences in Lublin, over the period 2010–2013. The obtained study results, compared to the treatment where the herbicide was applied without growth retardant, the weed control efficacy was significantly reduced when the herbicide was applied with the addition of Antywylegacz Płynny 675 SL, whereas combined application of the herbicide and the growth retardant Cerone 480 SL did not cause significant changes in weed infestation. The increase in mineral fertilizer rate contributed to increase number and dry weight of weeds compared to the treatment with standard fertilization.
