Özet
Citriculture is one of the most important agricultural sectors worldwide, with citrus fruits being widely cultivated across various regions. However, plant diseases caused by a range of phytopathogens pose significant challenges to citrus production. Several bacterial pathogens are known to infect citrus crops, leading to substantial economic losses. Notable bacterial agents includePseudomonas syringae pv. syringae (Pss), Xanthomonas citri subsp. citri, Xylella fastidiosa, and Candidatus Liberibacter spp., all of which are responsible for serious citrus diseases. The efficacy of current strategies for controlling bacterial diseases in citrus is limited. Cultural practices alone often fail to provide adequate disease suppression and have not been widely adopted by commercial growers. Chemical controls, such as copper-based bactericides and antibiotics, are used against certain bacterial pathogens. However, their effectiveness is increasingly compromised by the development of copper resistance in pathogen populations across many regions. Furthermore, growing public concern over the environmental and health impacts of pesticide residues has heightened the need for alternative or complementary disease management strategies. The antimicrobial properties of plant extracts and their major constituents, derived from a wide range of aromatic plant species, have been extensively studied against a broad spectrum of microorganisms, including bacteria, fungi, and viruses. In this study, the antibacterial activities of aqueous extracts obtained from various medicinal and aromatic plants including Allium sativum, Eucalyptus sp., Myrtus communis L., Nerium oleander, Origanum onites, Rosmarinus officinalis, Salvia officinalis, Thymus vulgaris, Thymbra spicata L. subsp. spicata, and Zingiber officinale were evaluated against Pseudomonas syringae pv. syringae (Pss) using the Minimum Inhibitory Concentration (MIC) tube dilution method. Among the tested plant extracts, A. sativum, O. onites, T. vulgaris, and T. spicata L. subsp. spicata exhibited antibacterial activity at concentrations of 5.50 μl/ml, 8.25 μl/ml, >64 μl/ml and >128 μl/ml, respectively. These findings suggest that certain plant extracts hold promise for the development of novel, environmentally friendly pesticides for the control of bacterial diseases in citrus cultivation. The research is funded by Cukurova University under project number FBA-2023-15707.
