Abstract
Rust is one of the most economically important foliar diseases of sunflower. The problem of sunflower disease control was considered. The article presents the results of a two-year experiment studying the efficiency of AMISTAR® Gold fungicide, concentrated suspension (active ingredient: Azoxystrobin 125 g/L, Difenoconazole 125 g/L) in sunflower hybrids in the Lower Volga region. Flowerbud development stage was the best application timing for increasing productivity. Therefore, sunflower yield averaged 3…4 c/ha. The biological efficiency of the fungicide ranged from 85 to 90 %. The calculation of economic efficiency showed 145…255 % profitability depending on the year.
