In vitro action of plant extracts on Botrytis gladiolorum (in English)

The in vitro effect of extacts from Berberis vulgaris and Chelidonium majus was studied against Botrytis gladiolorum fungus isolated from Gladiolus spp. We evaluated in vitro the effect of total extracts from Berberis vulgaris and Chelidonium majus on sporulation, and sclerotia formation. Plant extracts from Berberis vulgaris, containing 1% alkaloids, and Chelidonium majus, 0,25% alkaloids, were added to PDA at alkaloid concentrations of 25 to 250 μg/ml. Extract from both plants had increasing inhibitory activity against Botrytis gladiolorum fungus with increasing alkaloid concentration.
