Fusarium wilt of cucumbers has not been of importance in the United States, but is of considerable importance in other parts of the world. Three different isolates of Fusarium oxysporum f. sp. cucumerinum viz., #ATCC 16416 from Fla., #706 from Israel, and C732601 from Japan have been used in our inoculations. Cultivars ‘Ashley’, ‘Bet Alpha’, and ‘Shimoshazujihai’ were susceptible to all isolates.
