Fusarium oxysporum and/or F. proliferatum were isolated from all asparagus spears with brown spots (which indicate an infection) and from almost all spears without spots. The presence of Fusarium spp. and their toxins in the basal parts of asparagus spears was analyzed. Fumonisin B1 (FB1) and moniliformin (MON) were found in spears with brown spots and those without disease symptoms. FB1 was determined in the concentration range 0.16-152.68 ng g-1 (mean 7.52), while moniliformin was detected in the range 15.30-585.00 ng g-1 (mean 121.00). Only in 10% analyzed spears were metabolites not detected.
