SUMMARY Infection by Sclerotinia narcissicola Greg, was observed in narcissus bulbs during autumn, in leaf initials colonized by bulb scale mites ( Steneotarsonemus laticeps (Halb.)), and on lesions of varying extent on the corresponding tissue after emergence. Presence or absence of smoulder sclerotia on outer scales of bulbs was not related to the incidence of infection of shoots. There was no evidence that smoulder was reduced by treatment for control of bulb mites ( Rhizoglyphus echinopus (Fum. & Rob.)).
