Crop pathogen management is a priority for sustainable agriculture development. Indeed, the large use of pesticides is threatening both human and environmental health, while simultaneously pushing antimicrobial resistance occurrence. Although it is not trivial to develop solutions concurrently durable, effective and environmentally neutral, exploiting defense arsenal already present in natural ecosystems represents a promising approach to meet sustainability criteria. Essential oils (EOs) are naturally occurring compounds displaying a potent antimicrobial activity. Indeed, they can have multiple targets among molecular and structural components of microbial cells. However, their high extraction cost, low stability in the environment and poor water solubility slow down their potential application in crop protection. Modern approaches, like nanotechnologies, can provide solutions to the above-mentioned issues and, at the same time, can outperform the antimicrobial activity of EOs. The nanoformulation of EOs improves their solubility in water, hence their availability, and simultaneously can prevent their degradation in a natural environment like open fields. In this context, this work aimed to investigate the antimicrobial activity of 4 different EOs against Pseudomonas syringae pv. actinidiae, the causal agent of kiwifruit bacterial canker, evaluating bacterial in-vitro growth inhibition, and to evaluate the capacity of EO-based nanoemulsions to enhance their activity for further application in kiwifruit protection against the bacterial disease.

Abstract
Crop pathogen management is a priority for sustainable agriculture development. Indeed, the large use of pesticides is threatening both human and environmental health, while simultaneously pushing antimicrobial resistance occurrence. Although it is not trivial to develop solutions concurrently durable, effective and environmentally neutral, exploiting defense arsenal already present in natural ecosystems represents a promising approach to meet sustainability criteria. Essential oils (EOs) are naturally occurring compounds displaying a potent antimicrobial activity. Indeed, they can have multiple targets among molecular and structural components of microbial cells. However, their high extraction cost, low stability in the environment and poor water solubility slow down their potential application in crop protection. Modern approaches, like nanotechnologies, can provide solutions to the above-mentioned issues and, at the same time, can outperform the antimicrobial activity of EOs. The nanoformulation of EOs improves their solubility in water, hence their availability, and simultaneously can prevent their degradation in a natural environment like open fields. In this context, this work aimed to investigate the antimicrobial activity of 4 different EOs against Pseudomonas syringae pv. actinidiae, the causal agent of kiwifruit bacterial canker, evaluating bacterial in-vitro growth inhibition, and to evaluate the capacity of EO-based nanoemulsions to enhance their activity for further application in kiwifruit protection against the bacterial disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
