Infection and symptom development by citrus scab pathogen Elsinoë fawcettii on leaves of satsuma mandarin

European Journal of Plant Pathology, 2017
Elsinoe fawcettii, a fungal pathogen causing scab disease in citrus, is one of the destructive diseases having an adverse role in the fresh fruit market. We observed the infection behaviour of E. fawcettii on young leaves of satsuma mandarin daily and described the time course of symptom development with a focus on morphological changes during disease ...

Epidemiology and Control of Greasy Spot, Melanose and Scab in Florida Citrus Groves

Pans, 1976
Abstract Three major fungal diseases in Florida citrus groves that require control by chemical sprays are greasy spot (Mycosphaerella citri), melanose (Diaporthe citri) and scab (Elsinoe fawcettii). The salient features of pathogen behaviour and epidemiology are reviewed for each of these diseases.

Transgenic citrus expressing the antimicrobial gene Attacin E (attE) reduces the susceptibility of ‘Duncan’ grapefruit to the citrus scab caused by Elsinoë fawcettii

European Journal of Plant Pathology, 2012
Citrus scab, caused by Elsinoe fawcettii (anamorph Sphaceloma fawcettii), is a common foliar fungal disease affecting many citrus cultivars, including grapefruit. No commercial grapefruit cultivar is resistant to scab, and the disease results in severely blemished fruit which reduces its marketability.

The Swingle Sphaceloma Hand Lens and Early Records of the Pathogene of Citrus Scab

Mycologia, 1948
Fawcett (1, p. 2) has written that "the first extensive scientific investigations of Citrus diseases in the United States from the standpoint of cause and control were begun [in Florida] by W. T. Swingle and H. J. Webber in 1892." In the division of the work, as Dr. Swingle has told me, one of the citrus diseases he investigated was "scab or verrucosis.

Cytology of Cork Layer Formation of Citrus and Limited Growth of Elsinoe fawcettii in Scab Lesions

European Journal of Plant Pathology, 2004
Ultrastructural aspects of host–parasite interactions were investigated in fruits and leaves of citrus (satsuma mandarin) infected with Elsinoe fawcettii. Fungal infection induced host tissues to form cork layers bordering the necrotic areas below the infected sites.
