Potato desiccation is a good agrotechnical tool that allows you to plan the timing of crop harvesting and to a certain extent regulate the structure of the crop and its qualitative characteristics. The article presents the results of research on the use of drugs carfentrazone-ethyl 480 g/l (standard), Sahara, CE; Sukhovay, WS; for potato desiccation in the conditions of the Moscow region. The studies used potatoes of the Sante variety – medium-early, universal use. The use of a Sugar desiccant, which has a translaminar effect, provides gradual drying of leaves and stems with a continuous flow of plastic substances from photosynthetic organs into the tuber, without a sharp violation of the conducting vessels. After 14 days after potato processing, the drying of the leaves was 2.5 times higher on the Sahara, CE variant, compared to the control. Processing potatoes with Sukhovay, WS, which has a contact effect, helps to significantly accelerate the drying of potato leaves and stems in a short period of time, the effectiveness is visible already on the next day 93.8% on the leaves and discoloration of the stems 27.9%. The combined use of two desiccants on potatoes with an interval of 7 days will help to achieve effective drying of the green mass without abrupt cessation of incoming plastic substances into the tuber. The use of desiccants, due to the outflow of plastic substances, increased potato yield by 0.2–0.9 t/ha, as well as the dry matter content – 0.2–0.9% and ascorbic acid – 0.4–1.0 mg. The use of desiccants on potatoes in the conditions of 2022–2023 contributed to an increase in the proportion of the fraction of tubers 30–55 mm from the gross yield.
Key words: desiccants, potatoes, drying dynamics, yield, biochemical parameters.
