Published studies to date have suggested that seed-yam (Dioscorea rotundata) production in Nigeria using minisett (∼0.025 kg) technology or an adapted form of the technology using larger setts (0.08 to 0.1 kg) was not profitable. But these studies were often conducted under artificial conditions ...

The yam nematode, Scutellonema bradys, is a major threat to yam (Dioscorea spp.) production across yam-growing regions. In West Africa, this species cohabits with many morphologically similar congeners and, consequently, its accurate diagnosis is essential for control and for monitoring its movem...

Plant volatile signatures are often used as cues by herbivores to locate their preferred hosts. Here, we report on the volatile organic compounds used by the subterranean root-knot nematode (RKN) Meloidogyne incognita for host location. We compared responses of infective second stage juveniles (J...

Endophyte-enhanced tissue culture banana in East Africa: a novel way to combat soil-borne banana pests
The burrowing nematode (Radopholus similis (Cobb) Thorne) and the banana weevil (Cosmopolites sordidus Germar, Coleoptera: Curculionidae) are major pests of banana (Musa spp.) in the Lake Victoria basin region of Uganda. Among biological options to control the two pests is the use of non-pathogen...

Dual inoculation of Fusarium oxysporum endophytes in banana: effect on plant colonization, growth and control of the root burrowing nematode and the banana weevil
In studying plant colonization by inoculated Fusarium oxysporum endophytes, it is important to be able to distinguish inoculated isolates from saprophytic strains. In the current study, F. oxysporum isolates were transformed with the green (GFP) and red fluorescent protein (DsRed) genes, and beno...

Beauveria bassiana, which is effective against a range of insect pests, is the most researched and commercialised fungal biopesticide. Laboratory and screenhouse studies have revealed that this entomopathogenic fungus has great potential for use against the banana weevil, Cosmopolites sordidus. H...

The ability of soybean to symbiotically fix Nitrogen (N) was found to be substantially reduced (p≤0.05), after inoculation with root-knot nematode (Meloidogyne incognita). Galling, which is a commonly used indicator of root-knot crop damage, may provide less accurate information about reductions ...

Twenty strains of arbuscular mycorrhizal fungi (AMF), native to West Africa, and three commercial AMF, were evaluated for their protective effect against root-knot nematodes, Meloidogyne spp., in pots and field experiments in Benin. In pots, these strains were assessed in sterilized soil followin...

Sub-Saharan Africa needs to produce more food, feed, and fiber to support its growing population and intensification of smallholder agriculture is a crucial component of any strategy towards this goal. Sustainable Intensification (SI) acknowledges that enhanced productivity needs to go hand in ha...
