The study of the effect of treating seeds and plants of seed hemp with pesticides on morphometric indicators and economically valuable traits was carried out in 2020-2023 in the conditions of the Federal Research Center for Bast Fiber Crops – Separate division "Penza Research Institute of Agriculture" in the Penza region. Compositions of drugs with insecto-fungicidal action and a growth regulator used when treating seeds in combination with treating plants with an insecticide provided suppression of seed infection, a decrease in the prevalence of root rot and a protective effect against hemp flea beetle. Pesticides contributed to an increase in the morphometric parameters of hemp plants, the weight of 1000 seeds, influenced the oil content in the seeds and the collection of oil, as well as the content in the stems and the collection of fiber. A high increase in stem yield was obtained by treating plants with the Samurai Super insecticide and seeding material with compositions of Celest Top + Benorad and Tabu + Bunker 2.4 and 2.1 t/ha. A significant increase in seed yield was formed when fungicides Benorad and Bunker were used in dressing mixtures in combination with Celest Top, CS 0.40 and 0.39 t/ha; Tabu, VSK – 0.30 and 0.33 t/ha with the use of the studied insecticide during ground treatment of the crop. At the same time, in these options, fiber collection increased by 0.57-0.71 t/ha, oil collection – by 0.11-0.12 t/ha.
