In 2021\u20132023, the effect of Gaur, KE (240 g\/l) and Gezagard, KS (500 g\/l) herbicides on weed infestation of Master sunflower crops was studied in the steppe zone of the Kabardino-Balkarian Republic. The experimental design included comparison of variants with and without a herbicide background at different application rates: 1 \u2013 control (economic); 2 \u2013 control without weeds &nbsp;(weeds &nbsp;were &nbsp;removed &nbsp;manually &nbsp;as &nbsp;they &nbsp;appeared on crops during the sunflower growing season); 3, 4; 5 \u2013 application of different doses of herbicides to the soil. A high degree of suppression of common ragweed (85.0\u201390.8&nbsp;%) and other species (73.0\u201389.6&nbsp;%) was noted against the background of application of the soil herbicide Gaur, KE in doses of 0.8 and 1.0 l\/ha, applied to the soil under \u201cblind\u201d harrowing. This protects against losses of up to 0.5\u20130.9 t\/ha of sunflower seeds compared to the data in the farm control (1.7 t\/ha). The calculations showed that against the background of changes in the weed-field cenosis, the economic efficiency of chemical weeding was revealed. In the variants with the use of herbicides, the cost of proceeds was 21,000\u201323,000 rubles\/ha against 15,000 rubles\/ha in the farm control. When using Gaur and EC at doses of 0.8 and 1.0 l\/ha, the profitability level was 114 and 122&nbsp;%, respectively.<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family has-extra-small-font-size wp-elements-6d0552507b3475246bb2b399754d74a9\" style=\"line-height:1.4\"><strong><em>Keywords:<\/em><\/strong> sunflower (Helianthus annuus L.), ragweed (Ambrosia artemisiaflia L.), herbicides, agroecosystems, weeds, crop infestation<\/p>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-lora-font-family wp-elements-14c5fcd9a450dd94d11f89bc959f2650\" style=\"font-size:12px;line-height:1.4\"><strong>For citation<\/strong>.
