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...

A new arbuscular mycorrhizal (AM) fungal species of the genus Acaulospora (Glomeromycota) was frequently recovered from both undisturbed and cultivated agro-ecosystems of sub-Saharan West Africa, namely in Benin. It abundantly reproduced spores in trap cultures using Sorghum bicolor, Dioscorea ca...

From a survey of arbuscular mycorrhizal (AM) fungi in agroecosystems in Central Europe and West Africa, an undescribed species of Acaulospora was recovered and is presented here under the epithet Acaulospora sieverdingii. Spores of A. sieverdingii are 60-80 μm in diam, hyaline to subhyaline to ra...

Tuber yields of yam (Dioscorea spp.), a main staple food in West Africa, are steadily declining per unit area, an incidence for which decreasing soil fertility due to increasing land pressure is largely blamed. Recent studies demonstrated the association of a plethora of arbuscular mycorrhizal fu...

In the Gulf region, coconuts are almost exclusively produced from palms growing in the Sultanate of Oman, particularly in the extreme south-eastern coastal plain of the Dhofar Governorate, and specifically within the city limits of Salalah, between the Jebel and the sea. The importance of these c...

A new arbuscular mycorrhizal fungus was isolated from the Southern Guinea savanna in Benin, which represents a tree-rich savanna in the transi-tion between the tropical atlantic rainforests and grass-rich savannas in sub-Saharan West Africa. The fungus was propagated in bait cultures and monospor...

Two Brazilian isolates and one Benin (indigenous) isolate of Neozygites floridana were released against the cassava green mite, Mononychellus tanajoa , in January 1999 in the Adjohoun district, Ouémé administrative region, Republic of Benin. Post-release monitoring conducted 8, 14, 22 and 36 week...

A new species of the arbuscular mycorrhiza forming Glomeromycetes, Racocetra tropicana,was recently recovered from the semi-humid Atlantic coast line of Northeastern Brazil and from sub-Saharan savannas of Benin (West Africa). It forms yellow to dark yellow glomerospores on (dark) yellow brown sp...

The rapid decline of soil fertility of cultivated lands in the sub-Saharan savannas of West Africa is considered to be the main cause of the increasingly severeconstraints of food production. The soils in this tropical area are highly fragile, and crop yields are limited bycharacteristically low ...
