In 2022 and 2023, a field plot trial with the maize hybrid P 9241 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 Adengo® 465 SC (225 g/l isoxaflutol + 90 g/l thiencarbasone-methyl + 150 g/l cyprosulfamide (antidote)), Gardoprim Plus Gold® 550 SC (312.5 g/l s-metolachlor + 187.5 g/l terbuthylazine), Camix® 560 SE (60 g/l mesotrione + 500 g/l s- metolachlor) and Stomp Aqua® (455 g/l pendimethalin). The herbicidal products were applied alone after sowing before germination of the crop. The weed infestation of the experimental field was presented by 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 infestation with these weeds resulted in a very low average grain yield for the untreated control (270.54 kg/da). The highest herbicidal efficacy as well as the highest seed yields after the alone application of Camix 560 SE was recorded.
