“Eficiencia de aminas en el control de sigatoka negra (mycosphaerella fijiensis) en el cultivo de banano (musa paradisiaca) en el campus La María”

Black sigatoka is the main disease that affects banana cultivation, in economic and productive terms. This research focuses on evaluating the efficiency of amines in the control of black sigatoka (Mycosphaerella fijiensis) in bananas (Musa acuminata AAA), through the variables residuality, efficacy and cost analysis. The treatments under study consisted of the T0 at a dose of 1.5 gal ha-1, T1 at a dose of 1 L ha-1, T2 at a dose of 0.7 L ha-1, T3 at a dose of 0.6 L ha-1 and T4 at a dose of 0.4 L ha-1. A completely randomized design was applied, Tukey's multiple range test (P <0.05) and the evaluation methodology was the single sheet test proposed by Stover. At 49 days after application, the following average results were recorded in the residuality variable: T0 20.83 c, T1 87.67 a, T2 89.42 a, T3 81.50 ab and T4 66.67 b. In the efficacy variable; T0 87.00 c, T1 14.33 a, T2 12.33 a, T3 18.17 ab and T4 33.00 b. In the variable costs analysis; T0 USD 03.68, T1 USD 27.68, T2 USD 23.28, T3 USD 22.88 and T4 USD 13.88. Treatment T2 was the mixture that presented the best results for the variables efficacy, residuality and cost analysis. Key words: Amines, Efficiency, Black Sigatoka, Fungicide and Residuality.
