Abstract
This disease is recorded and described from Kenya. The optimum temperature for both spore germination and mycelial growth of Ascochyta tarda Stewart was between 21 and 23° C. Spore germination was restricted at less than 100 % R.H., took place more readily on the upper leaf surface than on the lower and was stimulated by wounding. The available evidence indicates that A. tarda is a wound pathogen of Coffea arabica L.
