Control de la pudrición de corona de la fruta de banano a diferentes dosis de extracto etanólico de canela.

Abstract

The research was carried out at the Santa Inés Experimental Farm of the Technical University of Machala in the phytopathology laboratory in the year 2020-2021 that had the general objective of evaluating the antifungal effect of the ethanolite extracts of cinnamon (Cinnamomum zeylanicum) in the control of crown rot (Fusarium pallidoroseum) in organic banana fruit and as specific objectives, to determine the severity of the disease of crown rot in the different treatments, to determine the best dose of ethanolic extracts of cinnamon (Cinnamomum zeylanicum) in the control of crown rot this disease is caused by a fungus that infects the crown of the fruit is wound is caused at the time of selection and cluster design through the wounds generated by the curved, the test is carried out in order to improve productivity and efficiency of disease control, through a randomized design of eleven treatments with three repetitions.A vegetative extract was tested with different concentrations and a chemical control plus an absolute control that only applied water. The different extracts were prepared in different test tubes and we rooted up to 50 ml then we placed the treatments in different 150 ml manual sprayers. A parametric analysis of variance was carried out once it was performed using the SHAPIRO WILK test and the Homoscedasticity-Levene test, which indicated that the data did not meet this assumption, therefore, the non-parametric ANOVA (KRUSKAL WALLIS) was carried out. When observing the results of the Kruskal Wallisse Test, we affirm that the best treatment with the cinnamon extract was T3 (10% ethanol extract), these treatments showed less disease affectation, managing to inhibit the development of the pathogen. It was evidenced that T3 (10% ethanol extract) surpassed all other treatments, including the chemical treatment (T10) that is used in the postharvest process, the order of efficiency is followed by T1 treatments (1% ethanol extract). , T2 (5% ethanol extract), T6 (25% ethanol extract), treatment 10 (chemical treatment) and treatment 8 (35% ethanol extract) showed similarity. This makes T3 the best in the trial, due to the decrease in the progress of the disease and T9 (40% ethanol extract), T11 (absolute control) showed less efficacy.
