Late blight, caused by Phytophthora infestans, was epiphytotic in fields of tomatoes in Samaru in northern Nigeria between July and September 1978. This is the first time the disease has been reported outside the cool Jos Plateau. Preliminary screening indicated that some cultivars had tolerance to blight. When low volumes of captafol were applied at 7, 10, and 14 day intervals on 1.8 and 3.6 m swaths, none of the treatments was significantly different in the control of foliar, stem, and fruit infection.
