Tryptophol was identified as a major metabolite in the culture medium of Drechslera nodulosa. This compound produced necrotic lesions on goosegrass [Eleusine indica] at a concentration of 6.2 .times. 10-4 M in two different leaf bioassay tests. Tryptophol also caused lesions on a number of other monocots and dicots, but generally higher concentrations were required. Tryptophol was also detected in the leaves of goosegrass infected by D. nodulosum, but not in uninfected goosegrass.
