Amendment of PDA with 40 μg ofGE/cm3 inhibited mycelial growth about 50%. Drenching of carnation with 165 μg of GE/cm 3, immediately after planting, resulted in drastical decrease of colony forming units number of the pathogen and increased healthiness plant stand about 50%. Applied as gladiolus corm soak, GE at cone. 660 ug/crrr' decreased development of Fusarium rot of gladiolus clones at least twice.}, type={Article}, title={Biological activitv of grapefruit extract in the control ofFusarium oxysporum}, URL={http://czasopisma.pan.pl/Content/131207/PDF-MASTER/16_PLANT_41_4_2001_Orlikowski_Biological.pdf}, keywords={Biological control, gladiolus, population, healthiness, Fusarium, Carnation}, }
