In the growing seasons of 2020 and 2021, a field plot trial with the maize hybrid P 9241 (FAO 370) was conducted. The trial was performed on the experimental field of the department of “Agriculture and herbology” at the Agricultural University - Plovdiv, Bulgaria. The evaluated herbicidal products were Aspect® T (200 g/l flufenacet + 333 g/l terbuthylazine), Adengo® 465 SC (225 g/l isoxaflutol + 90 g/l thiencarbazone-methyl + 150 g/l cyprosulfamide (antidote)), and Merlin® Flexx SC 480 (240 g/l isoxaflutole + 240 g/l cyprosulfamide (antidote)). The herbicidal products were applied alone and in combinations after sowing before germination of the crop. The natural weed infestation of the experimental field was presented by the following late spring weed species: Setaria viridis L., Digitaria sanguinalis (L.) Scop., Chenopodium album L., Amaranthus retroflexus L., Xantium strumarium L., Abutilon theophrasti Medic, Datura stramonium L., Solanum nigrum L., and Portulaca oleracea L. The highest herbicidal efficacy, as well as the highest seed yields after the alone application of Adengo® 465 SC, was recorded.
