IN-VITRO CONTROL OF SOLANUM LYCOPERSICON(TOMATO) FRUIT ROT CAUSED BY FUNGI USING OCIMUM BASILICUM AND ASPILIA AFRICANA PLANT EXTRACTS
Abstract
Tomato fruit rot is a common problem in agriculture, leading to significant
economic losses. Fungal pathogens are the primary cause of this disease, and
traditional chemical fungicides have limitations in terms of efficacy and
environmental impact. Therefore, the use of leaf extract with
antimicrobial/inhibitory properties of Ocimum basilicum and Aspilia africana
on the fungal pathogens isolated from infected tomato fruits were
investigated. These extracts were tested against the fungal pathogen
identified from the infected tomato fruits, which were Alternaria solani and
Fusarium moniliformes with various concentration of the extracts ranging
from 10-100% were separately added to potato dextrose agar (PDA) media.
Among the two extracts with varying concentration, the antifungal effect of
Ocimum basilicum on the mycelia growth of the pathogens were significant at
30% concentration (p< 0.05), while the antifungal effect of Aspilia africana on
the mycelia growth of the pathogens were significant at 40% concentration
