Evaluation of protective fungicides, based on sulfur and copper, as an alternative to the carbamate family in the management of Black Sigatoka in banana cultivation

Abstract

The study was carried out in an experimental plot of banana, Cavendish cultivar in the Jesús María parish of the Naranjal canton, belonging to the province of Guayas. Different treatments were applied, in which the following products were used: Timorex gold, Pitcher in water and oil, top-cop, cari gold, vitality, vitanica rz and banole. The application of the treatments was carried out by spraying directed at leaf one, by the simple leaf method. Data collection will be carried out every 7 days until when the control treatment of leaf 1 shows burning in a minimum of 80%, the disease will be evaluated in development percentages according to Stover's methodology. The treatments were established by means of a completely randomized block design (DBCA) with nine treatments and four repetitions, with a total of 36 plants to be evaluated. As a result, we obtained that the treatment with the top-cop fungicide has the smallest affected leaf area and the smallest area under the disease progress curve (AUDPC), being statistically different from the rest of the treatments and followed in order of efficacy by the fungicide. pitcher in water It was evidenced by the simple leaf technique, that the use of the fungicide Top Cop, presented the smallest area under the progress curve lo in leaves 1 and 2 in the banana plant, compared to the rest of the fungicides, being the control with the highest levels of the disease.
