Rapid Evaluation of Salvia pachystachys Essential Oil against Three Colletotrichum Species Causing Anthracnose on Strawberries

Abstract

The objectives of this study were to identify the chemical composition of essential oil of Salvia pachystachys Trautv. (Lamiaceae) and to evaluate antifungal activity against plant pathogens that cause anthracnose, Colletotrichum acutatum J. H. Simmonds, C. fragariae A.N. Brooks and C. gloeosporioides (Penz.) Penz. & Sacc. Water-distilled oil of S. pachystachys collected from the eastern part of Turkey was analyzed by gas chromatography-mass spectrometry (GC-MS). Major components were identified as a-pinene (18.9%), (Z)-b-ocimene (11.8%) and 1,8-cineole (8.0%). The oil showed weak antifungal activity against three Colletotrichum species using direct-bioautography assay.
