POTENTIAL USE OF OLIVE OIL MILL WASTEWATER TO CONTROL PLANT PATHOGENS AND POST HARVEST DISEASES

Abstract

The antifungal activity of olive oil mill wastewater (olive OMW) was investigated. The effect of sterilized, filtered and non-sterilized olive OMW was tested in vitro a) on mycelium growth of Pythium spp., V. dahliae, S. sclerotiorum and F. oxysporum fsp. lycopersici on PDA medium, b) on sporulation of Pénicillium species and Botrytis cinerea on infected with the pathogen fruits (mandarin and red pepper) and c) on tomato plants (seedlings) infected with the fungus V. dahliae or S. sclerotiorum. The in vitro results shows that the filter sterilized olive OMW inhibits the growth of all tested fungi mycelium. Olive OMW decreased fungi spores (conidia) number on infected fruits and acted positively on tomato plant growth © 2020. CARPATHIAN JOURNAL OF FOOD SCIENCE AND TECHNOLOGY. All Rights Reserved.
