Efficiency of fungicides against dry rot sunflower

The results of a two-year experiment on the effectiveness of the application of fungicides Optimum (CE) and Pictor (CS) on sunflower crops in the Priazovskaya zone of the Rostov Region are presented in the article. The value of the saved crop was 2.8 t / ha when treated with Piktor and 3.0 t / ha when processing Optimum. The biological efficacy of the drugs was 69.1% and 67.0%, respectively. The calculation of economic efficiency showed the advantage of Optimum fungicide on the value of conditionally pure income - 1545 rubles / ha against 780 rubles / ha on the variant with Piktor.
