Physalis angulata L., an important host of Cercospora nicotianae ELL. and Ev. in Zaïre

Tabazaïre, Kinshasa, Zaïre.
Cercospora nicotianae is the most important tobacco leaf pathogen in Zaïre, provinces of Equateur and Shaba. Burley variety BanketA1 is as infected as flue-cured variety Speight G 28. Physalis angulata L., a wide spread wild solanaceous plant and even weed in tobacco fields, is really the main host for Cercospora nicotianae. The strain isolated from P. angulata was able to infect tobacco and vice versa. Physalis pubescens L. may also be occasionally infected. Other plants such as tomato and Nicandra physalodes (L.) Gaertner remain unaffected by artificial inoculation.
