Abstract
The efficiency of application of potato tuber dressing agents of the Gala variety in the Kirov region was studied. One of the reasons of potato yield reduction is diseases, pests and weeds. At that, only diseases can take away about 20% of the yield. Among the most harmful potato diseases are late blight, rhizoctoniose, early blight, anthracnose, fusarium, phoma disease, potato scab and other diseases. The experiments were conducted during 2021– 2023. The object of research were potato diseases: anthracnose, rhizoctoniose, potato scab on potato and mordant fungicides (Emesto Silver, SC; Celest Top, SC; Fludimax, SC). Disease incidence was recorded according to the generally accepted methodology. At the beginning of vegetation, the biological efficiency of the application of preparations was from medium to high and amounted to 34.5–96.3%. The highest efficacy was observed for the combined twoand three-component formulations of Emesto Silver and Celest Top (88 and 96%, respectively). Two preparations with the lowest lesions by the end of the growing season for potato scab – Emesto Silver and Celest Top (13 and 19%) – stood out. The highest yield increase was obtained with two-component preparation Emesto Silver (8.3 t/ha) and three-component preparation Celest Top (9.8 c/ha). It is recommended to use multicomponent preparations with high biological efficiency, such as Celest Top, which provided maximum yield increase in the studies, to obtain high and stable potato yields and maximum protection against diseases (anthracnose, potato scab).
