Effect of some Anthemis austriaca Jacq chamomile flowers extracts on some plant pathogenic fungi

Abstract

The aim of this study was to determine the effect of hot water and alcohol extracts of Anthemis austriaca flowers on four pathogenic fungi: Fusarium semitectum, F. solani, F.oxysporum and Rhizoctonia sp. Hot water and all of ethyl alcohol and methyl alcohol was used to prepare extracts. Concentrations of 60, 90, 120, 150 and 180 mg. ml^-1 extracts were applied. Results showed that there was no inhibitory effect of aqueous extracts of flowers   A. austriaca on all fungi studied and for the all studied different concentrations. The study showed a difference the inhibition percentage of alcoholic extracts by different fungi pathogen and concentration. It was found that the highest percentage of inhibition was 57.30% for methyl alcohol extracts of Fusarium semitectum at 180 mg. ml^-1. Results of ethyl alcohol extracts showed that the best result was at the same fungus F. semitectum registered 51.23%. Results showed the different inhibition percentage for all fungi according to the organic solvent for all the different concentrations. Also the results showed the inhibition percentage of methanol extract surpassed the inhibition percentage of ethyl alcohol for most of the tested fungi and most of concentrations.
