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...

The effects of soybean inoculation with arbuscular mycorrhiza fungus Glomus mosseae (200 sporesplant), the nodulating bacterium Bradyrhizobium japonicum (106 cellsplant) and the nematode antagonistic fungus Trichoderma pseudokoningii (6.8×107 sporesplant) were studied. Application of the microorg...

Yams (Dioscorea spp.) are food crops of growing significance in sub Saharan Africa. Unfortunately, nematodes are major pests to their production. A study was undertaken in major yam growing areas of Uganda to investigate the association of plant parasitic nematodes with damage symptoms. Nemato...

Les ignames (Dioscorea spp.) sont une culture alimentaire d’importance croissante en Afrique sub–saharienne.Malheureusement, les nématodes sont des parasites majeurs qui gênent sa production. Une étude était menéedans les principales régions productrices de l’igname en Ouganda en vue de pouvoir ...

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...

Yield response and economic performance of farmer selected and preferred elite tomato (Lycopersicon esculentum 'Tengeru 2010'); African eggplant (Solanum aethiopicum 'Tengeru white') and amaranth (Amaranthus cruentus 'Madiira I') cultivars were undertaken in four communities located in Babati dis...

In Uganda, nematodes have the potential to cause substantial yield losses, yet it is not known whether farmers have knowledge of the damage these pests cause. A participatory rural appraisal was therefore conducted to assess farmers' awareness of nematodes, and to determine the preferred traits i...

Beauveria bassiana is considered a virulent pathogen against the banana weevil Cosmopolites sordidus. However, current field application techniques for effective control against this pest remain a limitation and an alternative method for effective field application needs to be investigated. Three...
