Bioactivity of olive oil mill wastewater against grey mould disease

Abstract

The antifungal activity of olive oil mill wastewater (olive OMW) was investigated. Filtered and sterilized olive OMW was tested as growth inhibitor of Botrytis cinerea mycelium in vitro. The effect of filtered and sterilized olive OMW was also tested on strawberries fruits infected with the Botrytis cinerea in vivo.The results show that the filtered sterilized olive OMW inhibits the growth of Botrytis cinerea mycelium in vivo confirming the antifungal activity probably due to presence of the phenols phenol content of olive OMW solution. © 2020.
