This study was carried out get knowledge about fungicidal properties of vegetable extracts to the control of the pathogenyc fungi (Colletotrichum musae and Botrytis cinerea) in banana (Musa sapientum) and strawberry (Fragaria sp) during the pos harvest storage, at the National University of Colombia headquarters in Palmira. Ethanolics extracts of the following vegetable species were evaluated: Plantago major L, Ruta graveolens L, Lippia alba (Mill) NE BROS), Pteridium aquilinum (Kaulf) Maxon. The extracts were obtained by the percolation method starting from the macerated material (100 g) and 1000 ml of solvent. The fungi was isolated from the strawberry (Fragaria sp) affected by B. cinerea and banana Gross mitchel affected by C. musae. To evaluate the control of the fungi C. musae and B. cinerea sixteen treatments were used (four extracts of plants, two extraction media, two dilutions and three repetitions). Three control treatments were added: absolute (PDA); solvent (PDA + ethanol or water); and chemical (PDA + chemical fungicide). The dilutions were prepared with the solvent used to obtain the extract. The evaluation in vitro was maid with ethanolics extracts diluted at 25%, because these presented the best results in the previous tests. The results indicate that the ethanolic solvent decreased the development of the fungi in 68%. The fruits in which the etanolic extract of ruda and pronto alivio was applied presented bigger incidence and grade of severity.
