Abstract
This study examined the effect of crude
essential oils (EOs) of clove seeds on some soil-borne fungal pathogens of T.
occidentalis. Aqueous extraction method of 20g crude EOs from clove seed
was adopted, and it was replicated to 100%, 50% and 25% concentration levels.
The fungal isolates identified were Rhizoctonia spp, Fusarium spp, Candida spp
and Aspergillus spp. The infected soil had more occurrence of soil-borne fungal
pathogen than healthy soil. All the fungal isolates were inhibited mostly at
higher EOs concentration. Visual assessment method of percentage disease
incidence of T. occidentalis revealed that leaf spot (51.25%), rust
(30.00%), damping off (8.75%), chlorosis (6.25%) and necrosis (3.75%)
occurrences. Crude extracts of clove seed EOs exhibited antimicrobial effect on
the soil-borne fungal pathogen of T. occidentails and can be used as
biofungicide to improve agro-practices to ensure sustainable production of
vegetable.
