First report of Cercospora coffeicola causing cercospora leaf spot of castor beans in Brazil
Plant Disease 95 (11), 1479-1479
Abstract: Weedy castor bean (Ricinus communis) plants from a coffee farm in Minas Gerais State, Brazil, were grown in a green house and inoculated with the fungus Cercospora coffeicola which had been isolated from coffee. Coffee (Coffea arabica) plants were also inoculated as positive control. After 12 days the castor bean plants started to develop necrotic lesions that were black and purple with a yellowish halo and a pale white center. The pathogen was reisolated from the castor bean leaf spots and its pathogenicity was demonstrated by inoculation of coffee.
