Growth of Fusarium oxysporum (Schlencht) and Phoma exigua (Desm) isolated from Cowpea (Vigna unguiculata) in various concentrations of six different sugars

Abstract

A study was carried out on the growth of Fusarium oxysporum (Schlencht) and Phoma exigua (Desm) using six different sugars (sucrose, glucose, maltose, lactose, xylose and fructose) at various concentrations. The results showed that all the sugars supported growth of Fusarium oxysporum and Phoma exigua. The growth of Fusarium oxysporum and Phoma exigua in potato sucrose agar (PSA) attained optimum growth than glucose, maltose, lactose, xylose and fructose when used. Potato fructose agar supported the least growth of the fungi. Generally the concentration of sugars did not affect the growth of the organism.
