Using two commercially available arbuscular mycorrhizal fungal (AMF) products, one based on
Funneliformis mosseae and the other on Glomus dussii, an experiment was conducted to assess their
effect on yam growth and ability to suppress nematode damage in pots. Four yam cultivars (cvs) were
used: t...

The yam nematode,Scutellonema bradys, which can cause dry rot disease of yam (Dioscoreaspp.), was recorded forthe first time from Costa Rica in four species of yam occurring in the Atlantic and north regions. Morphometric measurements fromtwo populations from each region using ten female and 11 m...

Scutellonema spp. are widely distributed across tropical and subtropical regions of the world and are associated with numerous agricultural and horticultural crops. Identification of many Scutellonema species is not always reliable, in part because many species share very similar diagnostic chara...

Nine Nigerian populations of Scutellonema bradys, obtained from infected yam (Dioscorea spp.), were assessed following inoculation onto susceptible yam (Dioscorea rotundata) cv. TDr131 in pot and field experiments in Nigeria between 2002 and 2004. In addition, geographically separated populations...

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...

In Benin, yam production continues to face numerous production constraints, including yield and quality reduction by Scutellonema bradys. Implementation of efficient management techniques against this pest requires an improved understanding, including at the molecular level, of the pest. The curr...

Scutellonema bradys is the major nematode species that affect yam (Dioscorea spp.) production and storage in Benin. A nematode survey was conducted during the storage periods of 2002and 2003 in the yam-growing areas to study the distribution, population diversity and incidence of S. bradys on tub...
