The results showed no damage, indicating the effectiveness of the products in protecting against disease during storage. The sprouting of tubers proceeded in accordance with maturity groups and varietal characteristics, but treatment with “Potato Saviour” in combination with “Zalp” caused a slight delay in shoot development. Field observations confirmed the absence of plant disease damage, indicating the prolonged action of the preparations during the initial stages of growth. After harvesting, the tubers were inspected and it was found that, compared to the control variant, disease damage was reduced by 15–25%. In 2024–2025, the highest incidence of common scab and dry rot was found in the Zhytnytsia variety, ranging from 1.0 to 2.5% and 3.6 to 8.9%, respectively, and the lowest in the Medea and Misteria varieties, ranging from 0.5 to 1.2% and 0.4 to 1.0%, and from 1.2 to 3.1%, respectively. It was found that, regardless of treatment with preparations, the tubers of all varieties had sprouts at the time of inspection on April 3, with the percentage of sprouted tubers ranging from 97 to 100, which indicates that the physiological processes in the tubers proceeded in accordance with their genetic potential. It was established that both the yield and the structure hardly differed between the experimental variants and did not actually depend on the influence of the applied preparations. In general, the yield ranged from 17.9 t/ha (first variant, Misteria variety) to 44.9 t/ha (fourth variant, Mirami variety). The same applies to the structure of the yield: in all variants, the seed fraction prevailed from 47.6% (first variant, Tiras variety) to 88.7% (fourth variant, Miroslava variety).
