Dubois, T.Coyne, D.L.Felde, A. zum[Enhanced protection for tissue cultured banana plants]Enhanced protection for tissue cultured banana plants

Classical innovation adoption models implicitly assume homogenous information flow across farmers, which is often not realistic. As a result, selection bias in adoption parameters may occur. We focus on tissue culture (TC) banana technology that was introduced in Kenya more than 10 years ago. Up ...


Kabunga, N.Dubois, T.Qaim, M.[Heterogeneous information exposure and technology adoption: the case of tissue culture bananas in Kenya]Heterogeneous information exposure and technology adoption: the case of tissue culture bananas in Kenya

The amaranth leaf-webber, Spoladea recurvalis (Fabricius; Lepidoptera: Crambidae), is a serious pest of Amaranthus sp. in Africa and Asia. Apanteles hemara (Nixon; Hymenoptera: Braconidae) is by far the most important larval endoparasitoid of the amaranth leaf-webber. We examined the effects of h...

Beed, Fen D.Dubois, T.[The role of International Institute of Tropical Agriculture in biological control of weeds]The role of International Institute of Tropical Agriculture in biological control of weeds

The effects of nematode infection and mulching on plantain cv. Agbagba (Musa spp., AAB-group, false horn) yield and plantation longevity were examined in a field experiment at the High Rainfall Station of the International Institute of Tropical Agriculture (IITA) at Onne in southeastern Nigeria. ...


Coyne, D.L.Rotimi, O.Speijer, P.Schutter, B. deDubois, T.Auwerkerken, A.Tenkouano, A.Waele, D. de[Effects of nematode infection and mulching on the yield of plantain (Musa spp., AABgroup) ratoon crops and plantation longevity in Southeastern Nigeria]Effects of nematode infection and mulching on the yield of plantain (Musa spp., AABgroup) ratoon crops and plantation longevity in Southeastern Nigeria

Three bioassays were conducted to investigate the antagonistic effect of secondary metabolites produced by 5 endophytic Fusarium oxysporum isolates from banana (Musa spp.) plants in Kenya, against Pratylenchus goodeyi. Percentage paralyses were recorded 3, 6 and 24 h after exposure to culture fil...


Mwaura, P.Dubois, T.Losenge, T.Coyne, D.L.Kahangi, E.[Effect of endophytic Fusarium oxysporum on paralysis and mortality of Pratylenchus goodeyi]Effect of endophytic Fusarium oxysporum on paralysis and mortality of Pratylenchus goodeyi

Under laboratory conditions, nonpathogenic, endophytic Fusarium oxysporum inflicts high mortality among banana weevils and nematodes. Following inoculation into banana (Musa spp.) tissue cultured plants, successful colonisation is necessary for efficient biological control of these pests. The pat...


Paparu, P.Dubois, T.Gold, C.Niere, B.Adipala, E.Coyne, D.L.[Colonisation pattern of nonpathogenic Fusarium oxysporum, a potential biological control agent, in roots and rhizomes of tissue cultured Musa plantlets]Colonisation pattern of nonpathogenic Fusarium oxysporum, a potential biological control agent, in roots and rhizomes of tissue cultured Musa plantlets

The leaf-webber Spoladea recurvalis F. is the most devastating pest of amaranths in East Africa. Recent collaborative research in Asia and East Africa revealed one highly resistant amaranth accession (VI036227) to the pest and seven moderately resistant ones (RVI00053, VI033479, VI044437-A, VI047...
