Resumo

Abstract: The anthracnose caused by Colletotrichum musae and soft rot caused by Rhizopus sp are post-harvest diseases that influenced quality of exported fruits. To control these diseases fungicides are used, but in light of these waste products in the fruit and the environment, alternative control methods such as using biofungicides have been studied. The objective of this study was to evaluate the effect of pequi oil on mycelia growth and sporulation of Colletotrichum musae and mycelia growth of Rhizopus sp. in vitro. The oil was added in aliquots of 5, 10, 15, 20, 25, and 50L in the center of Petri dishes containing approximately 15mL of Potato-Dextrose-ar (PDA) and distributed over the surface of the medium with Drigalskys handle. After 24 hours, a disc of 8mm diameter from mycelium of fungi was peaked to the center of the plates. As a control, were used Petri dishes containing only PDA. Five replicates were used for each aliquot. After analysis, it was concluded that the pequi oil is ineffective for controlling these pathogens because induced mycelium growth and sporulation.
