Abstract
This study was carried out to : (1) evaluate effectively of clove tree oil (Eugenia caryophylata Thunb) against the growth of Pythium aphanidermatum In Vitro . (2) Determine the effective extract concentration on seedling damping - off caused by pathogen on cucumber In Vivo , and (3) Identify the active component (s) of the
effective Clove oil.
The results showed that Clove oil extracted by steam distillation at 250 , 500 and 1000 ppm inhibited the growth of P. aphanidermatum by
33.3 , 100 and 100%.
Thin layer chromatographic analysis of the clove oil revealed that
Eugenol was the active component against the pathogen .
As consequence artificially contaminated soils , drenched with clove oil at 2000 ppm was significantly reduced the damping - off on
cucumber by both pathogens .
