FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Method for pre-planting treatment of seed potato tubers with liquid biostimulant involves treatment of seed potato tubers in a vessel filled with a biostimulant, using a working element installed in vessel. Biostimulant is potassium/sodium humate with trace elements with concentration of 5-5.2 g/l of active substance at consumption rate of 40-50 l solution per ton of seed potato. Working element for treatment of tubers is a centrifugal mixer with rotor in form of a plastic disc with concentrically installed four thin-wall wings, wherein treatment is carried out with constant stirring for 2-3 minutes.
EFFECT: higher quality of sowing material, preventing damage of tubers planting potatoes, simple method of treatment and possibility of providing treatment of tubers of various shape and size.
