摘要：There are important benefits in finding environmentally friendly methods that can replace pesticide in some plant biotic stress factors, by integrated pest management principles. Besides, it is a necessity to improvement and adapt alternative methods or technical to chemical control to sustainable agriculture plant productions. This study was carried out to determine extracts obtained from the Crambe oriatua-lis naturally grown in Kir§ehir (Turkey) locations, total phenolics, total flavonoids, antioxidant, antifungal and biohcrbicidal activity. In the study. 1,1-diphcnyl-2-picrylhydrazyl (DPPH), Trolox Equivalent Antioxidant Capacity (THAC), Ferric ions (Fe3+) reducing antioxidant power assay (FRAP), Copper Reduction Power Activity (CUPRAC), Total phenolic and Flavonoid analyzes of plant extracts were investigated. The antifiingal activity of plant extracts was determined against Ahemaria solani, Rhizoctonia solani, Verticillium ciahliae and Fusarium oxysporm f. sp. radicis-lycopersici. Also, the biohcrbicidal activities of the extracts in the Am-aranthits retroflexus L. diul Rwnex crispus h. seed germination and seedling development were also examined. As a result of the antioxidant study, it was determined that different chemical solvent extracts obtained from the plant had remarkable antioxidant activity. The total phenolic and flavonoid were determined to be limit in terms of C. orietitalis. On the other hand, methanol extracts decreased mycelial grovvlh of pathogens at different rates due to increasing doses, while the highest doses of sterile distilled water extracts inhibited 100% in vitro conditions. In the bioherbicidal study, it was determined that different plant extracts had significant hcrbicidal effects on A. retroflexus and R. crispus plants for germination and seedling development in vitro conditions.
