Three soybean [Glycine max (L.) Merr.]cultivars (Samsoy 1, TGx 1025-12E and TGx 996-26E) were evaluated for yield losses resulting from frogeye leaf spot caused by Cercospora sojina Hara. Replicated field plots were established at two locations in Nigeria that have a high natural infestation of C...

Southern blight of soyabeans caused by S. [Corticium] rolfsii, was observed for the first time in Nigeria, in field nurseries at Bukuru, near Jos in the Plateau State, in 1989. Over 40% of plants in plots of the cultivar TGx 1025-12E were blighted 2 weeks after the plots had been rogued to elimin...

An in vitro method for assessing cassava anthracnose disease (CAD) resistance was developed as a preliminary screen to a CAD‐resistant breeding programme. Potato dextrose agar (PDA) media was amended by extracts from the stem cortex of 10 cassava cultivars (30001; 30572, 30211, 88/02549, 88/00695...
