Carvone-Rich Essential Oils and Their Agrobiological Interactions: A Review

Area of Science:

• Agricultural Science
• Natural Product Chemistry
• Plant Science

Background:

• Carvone and carvone-rich essential oils (EOs) show promise in combating agricultural threats.
• Phytopathogenic fungi, insects, mites, nematodes, and weeds pose significant challenges to crop production.
• Synthetic pesticides raise environmental concerns and contribute to resistance development.

Purpose of the Study:

• To review the chemical composition, biological effects, and agricultural applications of carvone-rich EOs.
• To analyze the potential of these natural compounds as alternatives to synthetic agrochemicals.
• To discuss formulation strategies for enhancing the efficacy of EOs in field conditions.

Main Methods:

• Literature review of studies on carvone and carvone-rich EOs from plants like Mentha spicata, Carum carvi, and Anethum graveolens.
• Analysis of reported biological activities including antifungal, antibacterial, insecticidal, acaricidal, nematicidal, and herbicidal effects.
• Examination of innovative formulation technologies such as nanoemulsification and encapsulation.

Main Results:

• Carvone-rich EOs exhibit strong antifungal, moderate antibacterial, and significant insecticidal, acaricidal, nematicidal, and herbicidal properties.
• Biological activity is influenced by the specific chemical composition of EOs, varying by plant species and chemotype.
• Formulation technologies like nanoemulsification and encapsulation improve EO stability, bioavailability, and targeted delivery, overcoming volatility limitations.

Conclusions:

• Carvone-rich EOs are effective, low-risk agents for integrated pest, pathogen, and weed management in sustainable agriculture.
• These natural products reduce reliance on synthetic chemicals and mitigate resistance development.
• Further research and application of advanced formulations can optimize the use of EOs in agricultural settings.
