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 34 c/ha. The biological efficiency of the fungicide ranged from 85 to 90 %. The calculation of economic efficiency showed 145255 % profitability depending on the year.

Variety Testing

In a competitive variety trial, promising selection lines of sugar sorghum were studied in the Lower Volga region. Based on a set of signs, the best lines were identified, which are recommended for transfer to the State Variety Testing. Breeding lines, which are distinguished by high values of commercially valuable traits, can be used in planned crosses to create highly productive varieties and hybrids of sugar sorghum.
