- Аннотация: The effect of a new integrated system on the disease protection and yield increase in potato was studied. The proposed scheme includes the pre-planting treatment of seed tubers with modulated low-frequency pulse electric field (EF), in-furrow application of the azoxystrobin-containing Quadris fungicide during the planting, and the use of the Izabion biofertilizer, containing 62.5% of amino acids and peptides, in the tank mix with standard fungicides for the routine spraying of plants. The trials included six experimental schemes: (1) EF treatment followed by the standard scheme of fungicidal treatments; (2) Quadris application followed by the standard scheme of treatments; (3) use of the tank mix of Izabion and fungicides according to the standard scheme of treatment; (4) standard scheme of treatment (treated control) including five fungicidal sprayings (fluazinam (Shirlan), mephenoxam+mancoceb (Ridomil Gold MC, 2x), mandipropamid+diphenoconazol (Revus+Skor), and fluazinam (Shirlan)); (5) integrated protection scheme including all mentioned treatments; (6) unprotected control (no any treatments). The following parameters were assessed: the development of rhizoctonia infection on shoots, the development of late and early blight infections on vegetating plants, and the development of rhizoctonia and silver scurf infections on daughter tubers. In addition, the germination level of mother tubers was observed. The proposed integrated scheme significantly reduced the harmfullness of all studied plant diseases. Comparing to the treated control, the tested experimental scheme increased the yield and the marketable fraction of potato tubers by 8.5 t/ha and 33%, respectively; comparing to the unprotected control, the total increase made 14.7 t/ha and 53%, respectively, that makes it to be very promising for the potato-growing industry.
