During 2019-2021, the effectiveness of pre-planting treatment of potato tubers of the Sante variety against rhizoctonia disease and two schemes for the use of combined and contact fungicides in the conditions of the Moscow region was evaluated. The biological efficacy of the Idikum preparation for pre-planting treatment of tubers against rhizoctonia disease was 83.5%. All tested potato protection schemes during the growing season showed high efficiency in reducing the prevalence and degree of late blight and alternaria leaf spot. Depending on the prevailing weather conditions of the growing season, the scheme, where the contact-systemic preparation Metaxyl was used for the first treatment, provided an increase in yield by 36.3-47.5%, the second scheme – with the first treatment with the contact preparation Kumir – 25.8-36.3%.
