- A field study was conducted at Usmanu Danfodiyo University Dry land, Teaching and Research Farm during the 2013 cropping season to evaluate the efficacy of three fungicides on Cercospora leaf spot disease of cowpea. The experimental design used was randomized complete block design replicated three times with carbendazim 12%+ mancozeb 63% WP (A), hexaconazole 0.5% (B), tricyclazole 75% WP (C) and control (D) as treatments. The parameters assessed were disease incidence, disease severity, number of pods per stand, pod weight and 100 seed weight. Disease incidence and severity were found to be significantly (P>0.05) lower in cowpea treated with the fungicides particularly, carbendazim 12%+ mancozeb 63% WP and higher in the untreated cowpea. All the yield parameters were higher in plants treated with carbendazim 12%+ mancozeb 63% WP and lowest in the untreated cowpea.
