 ABSTRACT

Yield reduction in groundnut has been attributed to many factors including Cercosporaleaf spots disease. The present investigation was to assess disease incidence and severity of Cercospora leaf spot (CLS) of groundnut (Arachis hypogaea L.) in Mokwa Southern Guinea Savanna Agro Ecological Zone. Twenty farms in four villages were sampled for CLS in 2017 cropping season. The results revealed wide spread of the pathogens in all the farms, pointing to the challenges farmers face due to the effect of this pathogen in their groundnut farms. Resistant varieties to leaf spots may be cultivated or disseminated to areas with the high levels of Cercospora  . They can also be used in groundnut breeding programmes for further improvement for use by farmers in the area.

Keywords: Breeding programmes, Groundnut farms. Leaf spots disease pathogens, Resistant varieties, Yield reduction.
