The article contains results of efficiency evaluation of presowing treatment of hemp seeds of the varieties Vera and Nadezhda with seed treater agents Benorad, WP; Thiram, ASC; Bunker, ASC, with agrochemicals such as Lignohumat, Biocomplex-BTU and with growth regulator Albit, LP. The use of the studied chemicals in laboratory conditions contributed to an increase in the weight of seedlings with root in the Vera variety by 17.2-34.5%, in the Nadezhda variety by 5.7-31.4% compared to the control. In the field, in the Nadezhda variety, in the 4-5 leaf phase, the root weight in the varieties with treated seeds increased by 24.4-39.0%, the weight of the plant – by 29.3-46.3%. Treatment with seed treaters provided a decrease in seed contamination with phytopathogens in the Vera variety by 22.2-32.5%, in the Nadezhda variety – by 19.6-27.2%. The use of agrochemicals and a growth regulator led to the destruction of pathogenic mycoflora in the Vera variety by 11.5-14.1%, in the Nadezhda variety – by 4.9-16.2%. In the field, the biological effectiveness of root rot suppression with the use of seed treaters on the Vera variety was 50.4-91.3%, on the Nadezhda variety 71.1-85.6%; with the use of agrochemicals and a growth regulator in the Vera variety – 15.0-70.9%, in the Nadezhda variety – 23.3-63.3%. The highest productivity of hemp plants on the Vera variety was ensured by the use of Benorad, WP, Bunker, ASC, Lignohumat and Albit, LP chemicals. The increase in the yield of stems to the control was 13.6; 17.1; 17.0 and 15.9%, seeds – 22.7; 18.2; 15.2 and 25.8%, respectively. By the Nadezhda variety, the highest yield of plants was established with the use of such chemicals as Bunker, ASC; Lignohumate and Albit, LP. The increase in the yield of stems to the control was 28.1; 32.8 and 28.9%, seeds – 22.7; 22.7 and 18.7%.
