Abstract
Early in February, 1947, an unusual disease was noticed in cotton plants at Lubaga in the Lake Province. All the plants on an area of thirty-five square yards were affected, and most were killed outright (fig. 1). From specimens sent to the laboratory the disease was diagnosed as Ascochyta blight, caused by the fungus Ascochyta gossypii Syd. and this diagnosis has since been confirmed by the Commonwealth Mycological Institute, Kew. Some weeks later the Province was visited by the Plant Pathologist, who, during a survey of the cotton grown in the Shinyanga and Mwanza areas, found no further definite outbreaks. In April, 1948, Mr. A. N. Prentice observed the disease in a small area at Ukiriguru, also in the Lake Province. Specimens sent to the laboratory were found to be typical.
