Influence of grapefruit extract (GE) on mycelial growth, spore germination, population density of Fusarium oxysporum f. sp. cyclaminis and F. oxysporum f. sp. dianthi and its effectiveness in the control of Fusarium wilt of carnation and Fusarium corm rot of gladiolus (F. oxysporum f. sp. gladioli) was studied. Amendment of PDA with 40 microgram of GE/cubic cm inhibited mycelial growth about 50 percent. Drenching of carnation with 165 microgram of GE/cubic cm, immediately after planting, resulted in drastical decrease of colony forming units number of the pathogen and increased healthiness plant stand about 50 percent. Applied as gladiolus corn soak, GE at conc. 660 microgram/cubic cm decreased development of Fusarium rot of gladiolus clones at least twice
