It was investigated 20 variants which included 3 variants by ClearField plus technology, 5 variants by ClearField technology, 5 variants by ExpessSun technology and 7 variants by conventional technology. All of variants are on herbicide Gardoprim plus gold 500 SC (S-metolachlor + terbuthylazine) - 3.5 l/ha, which treated after sowing before emergence of the sunflower. Under investigation were 4 sunflower hybrids (Helianthus annuus L.): hybrid Bacardy (by ClearField plus technology), hybrid Estiva (by ClearField technology), hybrid Sumico (by ExpessSun technology) and hybrid Arizona (by conventional technology). The highest seed yield is obtained at herbicide tank mixture Pulsar plus + Stomp aqua by Clearfield plus technology. Tank mixture Listego + Dash + Sharpen by Clearfield technology and Express + Trend + Select super by ExpressSun technology also lead to obtaining of high seed yields. Tank mixtures of herbicides Smerch, Pendigan, Wing, Raft, Pledge and Modown with Amalgerol premium by conventional technology have lower yields due to insufficient control of weeds as Xanthium strumarium L., Cirsium arvense Scop., Convolvulus arvensis L. in sunflower crops. Increase in seed yield is due to the greatest degree of increase in indexes seeds number per head, seed weight per head and 1000 seeds weight.
