One of the most important diseases that affect tomato cultivation is the wilt and rot of the crown and root caused by Fusarium oxysporum f. sp.lycopersici and F. oxysporum f. sp. radicis-lycopersici. Three physiological races (1, 2 and 3) of F. oxysporum f. sp. lycopersici (FOL) which are distinguished from each other by their different pathogenicity in different crops. To successfully select the most appropriate tomato cultivar, the form and race of F. oxysporum that is present in the soil of the plot must be identified. From the Department of Phytopathology and Plant Health of LABORATORIO AGRAMA we make available to Farmers, Seed and Seed Companies … the DETERMINATION OF FUSARIUM OXYSPORUM and its RACES, in soils, seeds, seedlings and tomato plant in the field.
