Cardamom contains powerful bioactive compounds such as cineole, terpinyl acetate, and limonene. These natural components have shown strong antifungal and insect-repellent properties.
When used in agricultural applications, cardamom extracts may act as a natural fungicide and biopesticide, helping protect date palms from harmful pests and fungal infections—supporting healthier, more resilient crops with reduced chemical input.
Insecticidal potential of cardamom and clove extracts on adult red palm weevil Rhynchophorus ferrugineus
Al Dawsari Mona M. Saudi J Biol Sci. 2020 Jan;27(1):195-201. doi: 10.1016/j.sjbs.2019.07.009. Epub 2019 Jul 20. PMID: 31889836; PMCID: PMC6933195.
A laboratory study tested the toxicity of cardamom and clove seed powders and extracts against the red palm weevil (Rhynchophorus ferrugineus). Cardamom powder (5 mg) caused 93% mortality after one day and 100% after two days. Clove powder (7 mg) caused 100% mortality after three days. All extract concentrations from both plants led to 100% mortality within three days. GC-MS analysis identified key compounds, including eugenol and two novel terpenes. The study highlights the potential of using natural plant-based pesticides as safer alternatives for pest control.

Chemical composition and antifungal activity of five essential oils and their major components against Fusarium oxysporum f. sp. albedinis of Moroccan palm tree
Rahmouni, Abderrahmane & Saidi, Rabah & Khaddor, Mustapha & Pinto, Eugénia & Silva, Joaquim & Maouni, Abdelfettah. (2019). Euro-Mediterranean Journal for Environmental Integration. 4. 10.1007/s41207-019-0117-x.
A study evaluated the antifungal effects of essential oils (EOs) and their major components from five aromatic and medicinal plants against Fusarium oxysporum f. sp. albedinis, the fungus causing Bayoud disease in date palms in Morocco. EOs were extracted via hydrodistillation and analyzed using GC-MS. The most effective EOs were from Origanum compactum and Thymus satureioides, with major compounds carvacrol and thymol, showing strong antifungal activity (MFC 5 and 13 μl/ml) compared to the synthetic fungicide mancozeb (MFC 6 μl/ml). Thymol and carvacrol had the lowest MFCs (0.94 and 2.08 μl/ml). These results suggest that EOs, especially from O. compactum and T. satureioides, may serve as eco-friendly alternatives to synthetic fungicides for managing Fusarium wilt in Moroccan date palms.
