Biological and economic efficiency of fungicide amistar extra, sk for the collection of winter wheat varieties

The article presents practical material on the biological efficacy of the fungicide Amistar Extra, SK for the collection of winter wheat varieties of P.P. Lukyanenko KScRIA selection against leaf diseases. The material was obtained as a result of careful phytopathological observations. The conducted researches resulted in establishing the fact that the groups of early maturing and ultra maturing varieties according to the degree of resistance to the Septoria disease under field conditions of experimental training farm "Кuban" of the Kuban State Agrarian University can be divided into two groups - moderately stable and medium receptive groups. Application of fungicide Amistar Extra, SK for the collection of varieties of winter wheat against complex pathogens spotting allowed to get more than 9 t/ha of grain in 2015, the grades of Yesaul, Pobeda 50, Fisht, Tanya, Nota from the group of early maturing and ultra maturing varieties. From the group of middle maturing varieties such as the Pamyat’, Doca, Vostorg, Fortuna, Krasnodar 99, Fail has formed additionally from 9 to 13 t/ha.
