The objective was to evaluate the efficiency and the economic viability of the fungicides application, under a randomized block design in three factorial arrangement with three replicates, were utilized two cultivars ('BRS 220' and 'Vanguarda'); two timing of application (preventive and curative), and three active ingredients (tebuconazole, trifloxystrobin, tebuconazole + trifloxystrobin) and control. The results showed that the use of resistant cultivars is the most efficient with considerable economic return for both times of application, for moderately susceptible cultivars is essential the use of chemical control giving preference to the use of mixture of active ingredients of the triazoles and strobilurins group, in preventive applications.
