Antifungal Effect of Plant Extracts on the Growth of the Cereal Pathogen Fusarium spp.—An In Vitro Study

The aim of the study was a laboratory evaluation antifungal effect leaf extracts from yarrow (Achillea millefolium L.), tansy (Tanacetum vulgare sage (Salvia officinalis L.) and wormwood (Artemisia absinthium on fungi genus Fusarium, major cereal pathogens. used 5%, 10%, 20% concentrations plant extracts, evaluating their linear growth Fusarium avenaceum, F. culmorum, graminearum, sporotrichioides percentage inhibition compared to control. also included assessment content selected biologically active compounds in impact development aforementioned pathogenic fungi. total polyphenols flavonoids assessed by spectrophotometry, antioxidant activity determined using synthetic 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. Plant were characterized highest polyphenol contents (81.95 mg/mL) (21.12 other showed (102.44 mM Trolox). Wormwood extract contained lowest amount phenolic (flavonoids—5.30 mg/mL, polyphenols—43.83 mg/mL). inhibited mycelia fungal pathogen depending upon fungus species, type its concentration. (S) (T) plants at concentration demonstrated strong inhibitory against tested (the coefficient for S20: 83.53%; T20: 72.58%), while 10% 5% these less effective inhibiting (highest S10: 71.33%; S5: 54.14%; T10: 56.67%; T5: 38.64%). Yarrow (Y) (W) low fungistatic effect. Their level 63.82% (W20) 67.57% (Y20). had weakest (Y5: 34.09; W5: 42.06%; Y10: 45.01%; W10: 57.44%), even stimulating control ?23.7%). Based study, it found that each species reacted differently addition culture medium concentration, however avenaceum culmorum most sensitive fungi, least graminearum. results research are preliminary phase further field tests determine conditions, phytotoxicity biological stability, as well possibility producing biopreparation protect fusariosis.
