Evaluación de fungicida orgánico a base de taninos flavonoides, fenoles y saponinas para el control de sigatoka negra en banano

Abstract

The banana (Musa x paradisiaca) produced organically has become one of the most consumed fruits in the international market; For Ecuador, it is its main export fruit and many banana producers have tended to manage their cultivation organically, this has led to the search for new agricultural inputs, such as organic fungicides. The objective of this work was to determine the appropriate dose of an organic fungicide for the control of black Sigatoka (Mycosphaerella fijiensis Morelet) in banana. 100 plants per treatment were used, using the biological warning method to evaluate the efficacy of the fungicide on the young leaves of the plant. Within the three treatments carried out, the total number of cycles with the evaluated product were 6, data on the evolution of the disease were taken in Leaves 3 and Leaves 4. The results indicated T3 as the best, allowing the plants to arrive with an adequate number of leaves at harvest. The harvest of the fruit was carried out in the season (January-April) with the highest pressure of the disease in the evaluation area, showing a good performance of the fungicide, representing a new alternative in the market for the control of black Sigatoka, both for organic and conventional crops.
