Abstract
The essential oil of Ammoides pusilla was tested by the agar diffusion test
against 3 bacteria strains, Pseudomonas aeruginosa ATCC 27853, P.
syringae pv syringae and P. syringae pv mosprunorum, and the Minimal
inhibitory Concentration (CMI) and (QMI) Minimal inhibitory Quantity were
calculated against P. aeruginosa ATCC 9027. The results showed that the
1/2 dilution of the oil had the highest effect against the phytopathologic
bacteria strains (P. syringae pv syringae and P. syringae pv mosprunorum)
except P. aeruginosa ATCC 27853 which was less sensitive to all
concentrations. The CMI was 0.12% and the QMI was 10 µl after more than 6 days
of incubation. The oil effect is mainly due to it’s richness with thymol
(44.5%).
