Essential oil-based emulsions reduce bacterial canker on kiwifruit plants acting as antimicrobial and antivirulence agents against Pseudomonas syringae pv. actinidiae
Pseudomonas syringae pv. actinidiae (Psa) poses a significant threat to global kiwifruit production, with current control measures proving insufficient and fostering resistance development. Essential oils (EOs) offer a promising alternative due to their multifaceted antimicrobial and antivirulence mechanisms. This study evaluated the antimicrobial activity of various EOs—cinnamon bark (CIN), oregano (ORE), clove bud (CLO), and thyme (THY)—against Psa, in terms of growth and virulence traits. CIN exhibited the highest antimicrobial activity, followed by ORE and CLO EOs, while THY EO was less effective. Encapsulation of EOs into organic polymer-based emulsions enhanced their antimicrobial efficacy by improving bioavailability and stability while reducing the required dosage. Notably, CIN and ORE EO emulsions effectively reduced disease symptoms in kiwifruit under both in vitro and in vivo conditions. Mechanistically, these EOs demonstrated dual activity: direct antimicrobial effects likely via membrane alteration and indirect antivirulence effects, including the inhibition of biofilm production and type III secretion system induction. Field trials further confirmed the potential of EO-based formulations to reduce disease incidence and severity over a growing season. This study underscores the potential of EO emulsions as sustainable, cost-effective plant protection agents, aligning with the goals of environmentally friendly crop management strategies.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
