چکیده
Plant diseases are a threat for global food safety. Allium obliquum, Allium fistulosum, Allium ursinum, Aloe vera, Berberis vulgaris and Chelidonium majus plant extracts were obtained by the repercolation method and the antifungal activity was determined by the agar-dilution assay against Apergillus niger, Botrytis cinerea, Botrytis paeoniae, Fusarium oxysporum f. sp. gladioli, Fusarium oxysporum f.sp. tulipae, Heterosporium pruneti, Penicillium gladioli, Penicillium expansum, and Sclerotinia sclerotiorum. Phytochemical screening was performed for phenolic compounds, allicin and allin in Allium species, for aloine in Aloe vera, and for berberine in Berberis vulgaris. Ultrastructural changes induced by the plant extracts were visualized by electron microscopy. The antifungal effects of the studied plant extracts recommend them as candidates for the in vivo biological control.
