(Lam.)2026-02-12T08:34:24+00:00AWODUN, VICTOR ADEBISInoreplyijo@gmail.com<p><em>An experiment was carried out at the Faculty of Agriculture Central Laboratory, University of Ilorin, Ilorin, to assess the effects of selected essential oils (turmeric, clove, ginger, and lemon oils) against Scutellonema bradys infecting two stored sweet potato varieties (purple-fleshed and white-fleshed sweet potatoes). The essential oils were extracted using different solvent-based extraction methods. The experiment was laid out in a Completely Randomized Design (CRD) with four replications. Phytochemical screening was conducted to identify the bioactive constituents present in the oils. Data were collected on tuber rot, tuber appearance, and nematode population. Results showed that turmeric and ginger oils recorded the lowest nematode populations, ranging from 1.2–4.6 and 3.5–9.6, respectively, compared with the control (8.8–29.6) in purple-fleshed sweet potatoes. Phytochemical analysis revealed the presence of curcumin, phenols, eugenol, flavonoids, and other compounds that may be responsible for suppressing S. bradys. The study demonstrated that the essential oil treatments were effective in managing Scutellonema bradys in stored sweet potatoes and could serve as eco-friendly alternatives to synthetic nematicides.</em></p>2026-02-12T08:34:09+00:00##submission.copyrightStatement##
