From Biostimulant to Possible Plant Bioprotectant Agents

Abstract Aqueous extracts of plants with proven biostimulant activity may have the potential to inhibit growth and development plant diseasecausing fungi. The use in such a role has many advantages including fact that are biodegradable, less costly, readily available. Therefore, aim this study was evaluate aqueous infusions, decoctions, macerates extracted from burdock roots, wormwood leaves, lovage flax seeds, mullein flowers as bioprotectants. This carried out by testing vitro ability these bioprotectants fungi Thielaviopsis basicola (Berk. Broome), Fusarium avenaceum (Fr.) Sacc, culmorum (Wm.G. Sm.) Sacc., sambucinum (Fuckel), solani (Mart.) Rhizoctonia (J.G. Kühn), Botrytis cinerea Pers., Sclerotinia sclerotiorum (Lib. de Bary), causing disease soybean. antifungal macerates, decoctions determined diffusion method Petri dishes solid PDA medium showed tested able fungi, soybean diseases.
