Nufar basil (Ocimum basilicum "Nufar") is the first variety of Genovese basil (O. basilicum "Genovese") that is resistant to fusarium wilt. Fusarium wilt is a disease that causes sudden wilting and death in basil. It is caused by the fungus Fusarium oxysporum f. sp. basilicum, which attacks the xylem in the stem, blocking water uptake and leading to a characteristic sudden leaf wilt that does not respond to watering.[3]
