A study of smoulder (Sclerotinia narcissicola Greg.) of narcissus in northern Scotland

, : A study of smoulder (Sclerotinia narcissicola Greg.) of narcissus in northern Scotland. Acta Horticulturae (47): 125-129

Results of trials indicated that narcissus infection with S. narcissicola may reduce bulb yield and flower size. Symptoms in foliage and bulbs are more noticeable under wet than dry soil conditions. The disease is most prevalent in multiple bulbs and in the progeny of multiple bulbs. No evidence was obtained of transmission of infection by the bulb mite Rhizoglyphus echinopus.

Gray, E.G., 1971: Observations on Sclerotinia (Botrytis) narcissicola Greg., the cause of narcissus smoulder in northern Scotland. Roguing combined with spraying with dichlofluanid or mancozeb, from emergence to senescence, did not reduce infection by S. narcissicola. Leaf damage was greater on heavy soils than on soils with good natural drainage.
