| dc.description | Citrus fruits are agroindustrial resources of great importance due to their high demand and consumption in the world, in fresh and / or processed. Despite this importance, the levels of loss in post-harvest, caused mainly by fungal diseases such as mold or green rot (Penicillium digitatum), can reach up to 90 percent. For con- trol of P. digitatum, the main treatments are chemical applications with synthetic fungicides that may affect human health and environment, therefore efficient alternative methods such as microbial biological control, low toxicity chemicals and botanicals extracts are being considerated. On this base, the present work was carried out with the purpose of evaluating the effect of biological control of tannins from a green banana plant extract (Musa Paradisiaca) Cavendish varie- ty against rot caused by P. digitatum in commercial orange (Citrus sinensis) Valencia variety and mandarin (Citrus reticulata) Blanco variety. To measure the control effect, different concentrations of the extract green banana peel of 1000, 800, 600, 400 and 200 ppm were evaluated in in vivo with artificial inoculations of the pathogen for 22 days. These treatments were compared to an ab- solute control without treatment and the commercial fungicide Thiabendazole. The results obtained showed that the banana extract evaluated in different concentrations is not effective in reducing the pathogen growth compared to the untreated control in mandarin. In the case of orange, the extract evaluated in different concentrations showed reduction of growth on P. digitatum in comparison with the control, being the best treatment in concentration of 1000 ppm, with a reduction of 52.98 percent of the average of the radial growth of the fungus compared to the control and its biological activity was like the control effect of the commercial fungicide. Based on the results it was concluded that it is possible to relate the reduction growth of P. digitatum in mandarin and orange due to the tannins present in the green banana extract. | en |
