Abstract

The fungi cidal effect of four plants extracts namely Chiysanthemum
coman urn, Hyo-scyamum muticus, Ocimum basilicum and Solanum nigrum were
studied on growth and development of Fusanurn oxysporum which cause senous
diseases to members of most families. Among all species tested, O. basiiicum
extract was the most toxic to the tested fungus where its essential oil was more
effective than petroleum ether, dichioromethane, chloroform and methanol extracts.
They have EC5O’S as follows 723.6, 2331.8, 3539.9, 32200.3 and 70923.5 pg/mI,
respectively. Aroma chemical constituents of O. basdicurn leaves essential oil were
identified by gas chromatography!mass spectroscopy (GCIMS). The major aroma
constituents were eugenol (22%) which was the most effective and causes
complete inhibition growth at all concentrations, followed by I ,8-cineol (4%) which
showed no inhibitory effect and linalool (4%) was completely inhibited growth
at concentration of 4000 pg/mI, as they appeared in (GCIMS).
