Abstract

A plethora of vegetable compounds have antimicrobial activity and are natural antioxidants. Such compounds include oleuropein, its derivative hydroxtyrosol and resveratrol. In this project oleuropein, a grape pomace extract rich in resveratrol, as well as diluted olive mill waste water (OMWW), (by-product of olive oil extraction) were examined for their in vitro and in planta antimicrobial activity. All the extracts restrained radial growth of the fungus Colletotrichum higginsianum, as well as the oomycete Phytophthora parasitica var. nicotianae, and restrained conidial germination of Colletotrichum higginsianum and Botrytis cinerea. The activity against artificially inoculated detached tobacco leaves with Phytophthora parasitica var. nicotianae, as well as tomato and pepper plants, inoculated with Pseudomonas syringae pv. tomato, and pepper plants inoculated with Xanthomonas campestris pv. vesicatoria, which were treated with olive mill waste water and oleuropein extract, respectively, was verified. Oleuropein was also evaluated for its efficacy against artificial infection of young olive trees with Peudomonas savastanoi pv. savastanoi.
