Due to the emerging danger to the life of animals and people, today there is a turn to safe tech-nologies for controlling weeds by physical methods, both from the point of view of ecology and food safety, which include the destruction of plants using an electric current, in particular, high-voltage electrical pulses. The purpose of the study presented in the article is to identify and evaluate the effect of high-voltage electrical pulses on the irreversible damage to the intracellular structures of the plant tissue of weeds and unwanted grasses during their electric weed control, characterizing and eval-uating the parameters and modes associated with such processing. Experimental studies were car-ried out using a laboratory experimental setup that consists of a pulse voltage generator, a control circuit for a spherical forming spark gap, and schemes for measuring the electrical resistance of the plant tissue of the weed sample. The lesion level made it possible to control the depth of irreversible damage to the internal structure of the plant tissue of weeds by measuring its tolerance (the con-ductivity of the tissue increased with increasing damage to the cellular components of the tissue).The irreversible damage to the plant tissues of weeds for weeds of various biological groups, which is characterized by reaching the value of at least 4.0–7.5 degrees of damage to their tissues, can be acted on them with high-voltage electrical pulses in the treated tissue of an electric field intensity of at least 3.74 kV/cm, while ensuring specific processing electric energy for the reliable processing of weeds:for Euphórbiavirgáta,thisequals 5.2…17.5 J/cm3; for Amaránthusretrofléxus, it is 3.5…7.7 J/cm3; for Cirsium arvense, it is 2.7…10.9 J/cm3; for Sónchusarvénsis, it is 3.7…15.8 J/cm3; and for Lactúcata-tárica, it is 3.3…8.1 J/cm3.
