Evaluating host plant reaction of Musa germplasm to Radopholus similis by inoculation of single primary roots
A field experiment was established in the humid forest of southeastern Nigeria to assess host plant response to nematodes. Fifteen plantain and banana polyploid cultivars (landraces and hybrids) were tested in nematode-infested and non-infested fields on both plant and ratoon crops. The main nema...

Host plant resistance and tolerance of Musa landraces and hybrids to nematode infestation
Soil properties vary according to the topography. They affect water uptake and root exploration in the soil. Consequently, they may also influence the spread of plant–parasitic nematodes. This study reports on the effect of toposequence-related variations in soil on banana yields, foliar nutrient...

The influence of the topographic position within highlands of Western Rwanda on the interactions between banana (Musa spp. AAAEA), parasitic nematodes and soil factors
In Uganda, highland banana yields (5-30 t ha-1yr-1) are low in comparison to potential yields (70 t ha-1yr-1) due to high pest and disease pressure, soil fertility decline, and poor management. Although it is generally accepted that soil exhaustion is a major cause of low and declining yields, th...

Contribution of soil quality to banana yield problems and its relation with other banana yield loss factors
The burrowing nematode, Radopholus similis, is a serious threat to sustainable banana production worldwide. A promising method for nematode control is the development and deployment of nematode-resistant banana cultivars. This requires the identification of sources of resistance, which can then b...

The susceptibility and sensitivity to Radopholus similis and Helicotylenchus multicintus of 2-month-old plants derived from sword suckers (early screening) and of sword suckers of established 18-month-old mats belonging to 12 Musa genotype was investigated and compared. Differences in nematode po...

The effects of Radopholus similis and Pratylenchus goodeyi on growth, root health and yield of the East African highland cooking banana cultivar Mbwazirume (Musa AAA-group) were compared at Mbarara, Uganda, at 1430 m above sea level. In 3-year-old mats infected only with P. goodeyi, functional ro...

Endophytic fungi colonize most plants, causing no damage to their hosts, and often extending benefits, such as enhanced protection against various biotic and abiotic constraints. In the current study, three experiments assessed the activity of secondary metabolites of three strains of endophytic ...
