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...

Damage caused by plant-parasitic nematodes on East Africa Highland banana cultivar Mbwazirume was evaluated at Sendusu, Central Uganda. Banana plots were either nematode-infested or non-infested and received either continuous heavy mulch or were finger millet (Eleusine coracana) inter-cropped. An...

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...

Host plant response of seven Musa accessions to Radophlus similis and helicotylenchus multicintus was evaluated at Namulonge, Uganda.Suckers detached from first cycle harvested plants grown in inoculated and not inoculated fields were indexed for root and corm damage. Nematodes were extracted fro...

The damage potential of the plant-parasitic nematodes Pratylenchus coffeae, Helicotylenchus multicinctus and Meloidogyne javanica, was assessed on plantain (Musa spp., AAB-group) cv. Apantu-pa in microplots in Ghana. Hot water treated suckers, planted in 3 l plastic bags containing sterilised soi...

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...

Twenty five sites, representative of seven agro-ecological zones of enset (Ensete ventricosum) crops, were sampled between September 1998 and January 1999. At each site, five 1-2 year old enset plants were sampled to check for the presence of nematodes present in their roots. The predominant nema...

East African Highland bananas (Musa spp., AAA) also known by their vernacular name ‘matooke', are a major staple food for the densely populated high elevation regions of Eastern and Central Africa. Banana production, however, is declining due to increased pest and disease pressure. Nematodes are ...
