Resumen

Se determinó el efecto de la aplicación de los extractos etanólicos (EE) de hojas de Azadirachta indica check for this species in other resources ('nim'); Phyllanthus niruri check for this species in other resources ('flor escondida'); Calotropis procera check for this species in other resources ('algodón de seda'); Lippia origanoides check for this species in other resources ('orégano silvestre'); Gliricidia sepium check for this species in other resources ('mata ratón') y Heliotropium indicum check for this species in other resources ('rabo de alacrán'), colectadas en el estado Lara, Venezuela, en el control de la antracnosis ocasionada por el hongo Colletotrichum gloeosporioides check for this species in other resources en frutos de mango ( Mangifera indica check for this species in other resources ). El extracto se obtuvo por presión reducida y se determinaron los grupos de metabolitos secundarios (MS) presentes en ellos. El patógeno se hizo crecer en el medio nutritivo PDA. La determinación del efecto de los EE a una concentración de 2,5% se hizo bajo tres métodos de aplicación in vitro. Frutos de mango fisiológicamente maduros fueron tratados con los extractos al 2,5 % y luego inoculados con el hongo. Se encontró que las plantas diferían en los grupos de MS. El EE del L. origanoides y H. indicum, homogenizados en el medio, ocasionaron la mayor disminución del crecimiento micelial de C. gloeosporioides. Los EE de L. origanoides y G. sepium fueron los mejores tratamientos de postcosecha, ya que indujeron el 37 y 33 % menos de la enfermedad en los frutos de mango, respectivamente. Los resultados indican el potencial de los extractos para el manejo de la antracnosis del mango en postcosecha.

Abstract

The effect of applying ethanolic extracts (EE) of leaves of Azadirachta indica check for this species in other resources (′nim′); Phyllanthus niruri check for this species in other resources (′flor escondida′); Calotropis procera check for this species in other resources (′algodón de seda′); Lippia origanoides check for this species in other resources (′orégano silvestre′); Gliricidia sepium check for this species in other resources (′mata ratón′) and Heliotropium indicum check for this species in other resources (′rabo de alacrán′) collected in the state of Lara, Venezuela, on the control of mango anthracnose caused by Colletotrichum gloeosporioides check for this species in other resources was evaluated The plant extract was obtained by reduced pressure and the secondary metabolites (MS) were determined. The microorganism was grown on PDA media. The effect of the EE at 2.5 % concentration was evaluated following three methods of application. Mango fruits at the adequate ripening stage were treated with the concentration of 2.5 % and then inoculated with the fungus. Differences were found in the plants extracts with regard to the MS present. L. origanoides and H. indicum EE, homogenized in the medium caused the highest inhibition of C. gloeosporioides mycelium. The EE of L. origanoides and G. sepium were the best postharvest treatment since they induced 37 and 33 % less disease in mango fruits. Results indicate the potential of plant extracts to handle mango anthracnose in postharvest.
