Abstract: The invention provides extracts and preparations based on the species Tulbaghia violacea (Harv.) (wild garlic), which elicits a significant antimicrobial, preferably antifungal activity in vitro and in vivo, even under field and glasshouse conditions. Moreover, these extracts deriving from the soil parts as well as of the aerial parts of the plant elicit a significant bio-stimulatory activity, expressed, above all, by an increased growth metabolism supporting seed growth. Furthermore, combined extracts or preparations from Tulbaghia violacea and species of the genus Agapanthus show a higher antifungal and bio-stimulatory efficacy as compared to the extracts or preparations of the single species, indicating that synergism is participated in the involved biological processes.

Abstract: The invention relates to plant extracts, especially based on species of the genus Agapanthus and combinations thereof with other extracts deriving from other plants. The invention further relates to the isolation, purification and identification of compounds in these extracts. The plant extracts and the isolated substances show significant antimicrobial activity, especially antifungal activity, and bio-stimulatory efficacy, when applied to other plants in vitro and in vivo, including under field conditions. The products according to this invention are suitable to be used as plant protecting agents for many crops and economic plants as an alternative for chemical pesticides.
