D1-alanine and dl-valine, when added as an extra nitrogen for fortifying the already present inorganic nitrogen source, actually acted as growth retardant for F. oxysporum f. udum (Butl.) Sn. et H. Sporulation of microconidia was indifferently affected by these two amino acids. DI-valine stimulated microconidial formation in young cultures only. In both young and old cultures the lowest concentration of dl-valine depressed macronidial sporulation. In old cultures the lowest concentration of valine stimulated chlamydospore differentiation rapidly, higher concentrations being less effective. D1-alanine, as an additional nitrogen source, depressed both macro- and microconidal sporulation. It did not even invigorate chlamydospore formation. D1-isoleucine, on the other hand, belongs to the category of growth promoters and profuse and stimulative sporulators of macro- and microconidia. This pathogen needs very specific and preferential doses of the three amino acids, if these are used as a booster in addition to the already present nitrogen source. The response, both in terms of mycelial growth and sporulation of the three spore forms, was also conditioned by the age of the culture.
