Jibrin, M.O.Timilsina, S.Potnis, N.Minsavage, G.V.Shenge, K.C.Akpa, A.D.Alegbejo, M.Beed, Fen D.Vallad, G.E.Jones, J.B.[First report of Xanthomonas euvesicatoria causing bacterial spot disease in pepper in Northwestern Nigeria]First report of Xanthomonas euvesicatoria causing bacterial spot disease in pepper in Northwestern Nigeria

Techniques for evaluating biological control of cassava mealybug (Phenacoccusmanihoti Matile-Ferrero), mango mealybug (Rastrococcus invadens Williams), and spiralling whitefly (Aleurodicus dispersus Russell) are described. In each case, two exotic hymenopterous parasitoids were introduced. Alone ...

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...

Fifty-five samples of diseased cassava (Manihot esculenta) crowns and shoots and discoloured chips were collected from Benin and Cameroon, Africa. Pieces of infected tissue were cultured on agar and incubated for a week. Over 36% of fungal isolates were Fusarium spp. Of the Fusarium isolates, 55%...

Cassava brown streak disease (CBSD), caused by cassava brown streak ipomoviruses (CBSIs), has become the most debilitating biotic stress to cassava production in East and Central Africa. Lack of CBSD-resistant varieties has necessitated the search for alternative control measures. Most smallholde...

Vascular wilt of banana and plantains, also known as Moko disease, is caused by Ralstonia solanacearum (Rs) phylotype II, and is the main bacterial disease affecting these crops in the Americas. Upon comparative sequence analysis of 44 Rs genomes we developed an improved PCR protocol based on the...

Xanthomonas vasicola pv. musacearum (Xvm) which causes Xanthomonas wilt (XW) on banana (Musa accuminata x balbisiana) and enset (Ensete ventricosum), is closely related to the species Xanthomonas vasicola that contains the pathovars vasculorum (Xvv) and holcicola (Xvh), respectively pathogenic to...
