The purpose of this study was to demonstrate the efficacy of the herbicide Resital Duo (SE) against the weed Polygonum aviculare, from a winter wheat crop. The observations were made in a wheat crop located in the western part of Romania, respectively in the Western Plain. Research has been conducted during the agricultural years 2022-2023, and included determinations on the effects of vegetation treatments with the herbicide product Resital Duo (SE) (452.42 g/l 2.4-D 2-Ethylhexyl Ester (EHE) + 6.25 g/l Florasulam.), applied in 4 variants and 3 different doses (untrated, 0.2 l / ha, 0.4 l / ha, 0.6 l / ha. Therefore, a monofactorial experience was set up in the field, placed according to the method of randomized blocks, in four repetitions. 15 days after application of Resital Duo (SE) (452.42 g / l 2.4-D 2-Ethylhexyl Ester EHE) + 6.25 g / l Florasulam), the most effective treatments in experience were variant 3 (0.4 l / ha) and variant 4 (0.6 l / ha), with an efficacy of 57.5%, respectively 77.5%. After 30 days of the application of the Resital Duo (SE) product, the most effective treatments in our experience were both variant 3 (0.4 l/ha) and variant 4 (0.6 l/ha), which accumulated an efficacy of 92.5%, respectively 99.5%. The applied product did not create any kind of phytotoxicity to our crop, at any of the 3 doses tested, and the vigor of the wheat was maintained at the level of 100%;
