Antifungal Activities of some Salvia Species Extracts on Fusarium oxysporum f. sp radicis- lycopersici (Forl) Mycelium Growth In-vitro

Abstract

The antifungal effects of essential oils and plant extracts (water, ethanol and methanol) of Salvia cryptantha Montbret et Aucher ex Bentham, Salvia tomentosa Mill., Salvia officinalis L.(cultural form) grown in Tokat province was screened against Fusarium oxysporum f. sp. radicis-lycopersici. The essential oils and plant extracts of S. officinalis, S. cryptantha and S. tomentosa were determined to find the most effecient against F. oxysporum f. sp. radicis-lycopersici in vitro. Different volums of either essential oils and plant extracts were mixed with the sterile PDA to obtain various concentrations. The suplemented PDA were inoculated with agar disc (5 mm in diameter) of Fusarium oxysporum f. sp. radicis-lycopersici pathogens (from 7 day-old PDA cultures) were inoculated on medium. They were incubated at 25 +/- 2 degrees C for 7 days. Then the bloking fungal development was calculated. The highest effects on the development of mycelium of F. oxysporum f. sp. radicis-lycopersici has shown blocking rate of 62,71% with a S. officinalis essential oils, this was followed by S. tomentosa and S. cryptantha. Similar results were observed in plants extracts. The highest effects on the development of mycelium of F. oxysporum f. sp. radicis-lycopersici showed S. cryptantha plant extracts and this S. officinalis and S. tomentosa has followed.
