The response of yam (Dioscorea) cultivars to artificial and natural infections with minisett rot pathogens was investigated. None of the 20 yam cultivars were resistant to Sclerotium rolfsii [Corticium rolfsii] or Trichoderma longibrachyatum. Cultivars TDa 84/093, 85/236, 85/257, TDr 608, 745, 81...

Thirty isolates of Colletotrichum gloeosporioides f. sp. manihotis causal organism of cassava anthracnose disease (CAD), were collected from cankers on cassava stems in cassava-growing zones of Nigeria. Using a pathogenicity test, five virulent isolates (05FCN, 10FCN, 12FCN, 18FCN and 26FCN) were...

Forty-seven cultivars of cassava in IITA's trials were screened for their reaction to infection by Colletotrichum gloesporiodes f. sp. manihotis in the field. The following parameters were observed: (a) distance of first canker from the soil, (b) total number of cankers per plant, (c) size of can...
