Evaluación de fungicidas orgánicos para el control de mycosphaerella fijiensis en un cultivo de banano

Abstract

This study focused on evaluating the effect of organic fungicides for controlling Mycosphaerella fijiensis in a banana plantation. The research was conducted at the "Santa Inés" farm, where seven different treatments were applied and compared. The methodology included data collection on disease incidence and its analysis through a non-parametric analysis of variance, as normality (Shapiro-Wilk) and homoscedasticity (Levene) tests indicated that the data did not meet the necessary assumptions for a parametric ANOVA. The results showed that the treatments T7 (Esteres de Sorbitano), T4 (Melaleuca alternifolia), and T3 (Extracto de neem) were the most effective in controlling Black Sigatoka, with the lowest values of Area Under the Disease Progress Curve (AUDPC) at 34.58, 35.24, and 41.26, respectively. These figures exhibited statistically significant differences compared to the control treatment (T1), which had a value of 59.41. On the other hand, treatments T2 (Silicosulfocalcic Broth), T6 (Silicon Oxide), and T5 (Calcium Oxide) were not effective, showing significantly higher AUDPC values (117.71, 121.3, and 163.33, respectively) compared to the control. In conclusion, treatments T7, T4, and T3 proved to be viable options for managing Mycosphaerella fijiensis in organic banana crops, while treatments T2, T5, and T6 did not provide adequate disease control. These findings may guide future agricultural practices in selecting effective organic fungicides for this crop.
