Abstract
The importance of kiwifruit cultivation is increasing all over the world and Italy plays a key role being one of its larger producer. Bacterial diseases are the most dangerous pathogens of kiwifruit, in particular bacterial canker caused by Pseudomonas syringae pv. actinidiae.
Control through antibiotics and heavy metals points out environmental and safety issues, stimulating the search for alternative disease control measures. Aim of this Thesis was to investigate natural extracts and natural antagonists able to control kiwifruit bacterial diseases.
Some natural extracts showed antimicrobial activity, in particular garlic, pomegranate and lavender extracts were effective in the control of bacterial pathogens of kiwifruit as well as a biocontrol agent, strain hr63 belonging to Pseudomonas fluorescens species, which was able to control bacterial kiwifruit pathogens both, in in vitro and in vivo tests.
