The study was conducted to test the antifungal efficacy of J. curcas leaf extracts against Phaeoisariopsis personata (causal
pathogen for groundnut late leaf spot disease) under in vivo conditions, and to identify important phytochemical constituents
exhibiting antifungal properties. The results showed that the greatest reduction of late leaf spot disease incidence was achieved
by all the Jatropha curcas leaf extracts at the highest concentration (0.5 mg mL-1
) as 36.89, 36.59 and 24.67% for chloroform,
ethyl acetate and methanolic extracts, respectively. Subsequently, J. curcas leaf extracts treatments enhanced the growth and
yield of groundnut compared with the control (untreated). The antifungal effects of J. curcas were supported by the presence
of phytochemical constituents identified by GC-MS. Hexadecane; n-hexadecanoic acid; phenol, 2, 4 bis (-dimethylethyl);
phytol and hexadecanoic methyl ester were detected as major phytocompounds in J. curcas leaf extracts that were possibly
responsible for the antifungal activity. © 2021 Friends Science Publishers
