In 2018-2020, at the experimental field of IASS "Obraztsov Chiflik" - Ruse, the effectiveness of the herbicides: Adengo 465SK (Isoxaflutol - 225 g l-1; Thiencarbazone-methyl - 90 g l-1, Cyprosulfamide (antidote) - 150 g l-1), Laudis OD (Tembotrione 44 g l-1; Isoxadifen-ethyl (antidote) 22 g l-1) and Chemnico 25SK (Isoxaflutol - 225 g l-1; Thiencarbazone-methyl - 90 g l-1, Cyprosulfamide (antidote) - 150 g l-1), on the development of maize was studied. The negative impact of weeds on the growth and yield of maize, as well as the need for the use of new herbicides, formed the objective of the study: To determine the influence of some vegetation herbicides on the productivity and some structural yield elements in The average yield obtained after the use of Laudis OD and Chemnico 25SK herbicides exceeded the control variant by 10.98% and 6.99%, respectively. Herbicides had positive effects on some of the structural elements of the yield, which were with statistically proven differences. In conclusion, it should be noted that only by applying a complex approach to the entire crop rotation area, weed control in maize can be successfully carried out. [ABSTRACT FROM AUTHOR] |
