- Аннотация: In-furrow application of the Uniform fungicide (azoxystrobin + mefenoxam) during the planting of potato significantly reduces the late blight development in the course of a growing season. The effect has been observed in both laboratory and field trials arranged in 2012 and 2013 at the All-Russian Research Institute of Phytopathology. The in-furrow Uniform application followed by the common schemes of the foliar treatment with Ridomil Gold MZ, Revus Top, and Shirlan in a tank mix with the Izabion biofertilizer delayed the first late blight manifestations by 40 days as compared to the untreated control and by 27-30 days as compared with the common protection scheme, which did not include the Uniform application. The resulting increase in the total and marketable yields made 30.5 t/ha and 42%, respectively, as compared with the untreated control, and 7 t/ha and 13%, respectively, as compared with the common protection scheme. The reduction of the number of foliar treatments by one in the Uniform-including scheme did not significantly influence the total and marketable yields and the start of the disease. Thus, the addition of Uniform to the common potato protection schemes represents an efficient way to provide the late blight protection starting from the sprouting stage and to reduce the risk of the early infection of plants. In addition, it allows a user to delay the beginning of foliar spraying and to reduce their number without any losses in the plant protection efficiency; moreover, a significant increase in the total and marketable yields are provided.
