Twelve cassava (Manihot esculenta Crantz) genotypes were planted under natural field conditions for two different cropping seasons (wet and dry), in 1992 and 1993 at the research farm of the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. The trial studied the effect of p...

A study was conducted at the greenhouse of the international institute of Tropical Agriculture, Ibadan,Nigeria to investigate the synergistic relationship of xanthomonas campestris pv. Manihotics (causal agent of cassava bacteria blight CBB), and colletotrichum gloeosporiodes f.sp manihotics (cau...

A survey was carried out of 86 cassava fields in the lowland savanna; humid forest, mid-altitude savanna, and lowland humid savanna agroecological zones of Guinea. Each field was assessed for the incidence and severity of cassava bacterial blight (CBB), cassava anthracnose disease (CAD), Cercospo...

Cassava anthracnose disease (CAD) caused by the fungus Colletotrichum gloeosporioides f.sp. manihotis has become one of the major economic diseases of cassava in Africa. The expansion of cassava production farmlands particularly in the humid rainfall zones of West and Central Africa has led to an...

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...
