- Аннотация: Efficiency of the Zorvec™ Encantia® (oxathiapiprolin + famoxadone) fungicide against potato late blight has been evaluated under epiphytotic conditions comparing to the standard Ridomil Gold MC (mancoceb + mefenoxam) fungicide. Field trials demonstrated the best protection was provided by Zorvec Encantia: the corresponding AUDPC value was equal to 90, while that for Ridomil Gold MC and untreated control reached 232 and 3244 (LSD95 = 67.8). Biological efficiency of the tested and standard fungicides was 97 and 93%, respectively. Potato yield for the compared variants reached 8.6, 31.4, and 33.4 t/ha for the untreated control, Ridomil Gold MC, and Zorvec Encantia, respectively. Thus, application of Zorvec Encantia provided the maximum yield increase (24.8 t/ha), while that for Ridomil Gold was 22.8 t/ha. The quality of harvested tubers assessed after a one-month storage showed that both Zorvec Encantia and Ridomil Gold MC treatments significantly reduced the tuber blight level (25.5 and 25.1%, respectively) and increased the marketable fraction of potatoes by 50 and 48%, respectively.
