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...

Radopholus similisis a major pest of East African highland cooking bananas (Musaspp.) in Uganda. Non-pathogenic Fusariumoxysporumendophytes, isolated from bananas in farmers’ fields, have shown potential to reduceR. Similis numbers in tissue culture banana. The mechanism through which endophyte...

Defenserelated gene expression in susceptible and tolerant bananas (Musa spp.) following inoculation with nonpathogenic Fusarium oxysporum endophytes and challenge with Radopholus similis
Plant-parasitic nematodes cause serious damage on banana in Africa. Affected plants are less able to access nutrients and water, leading to yield losses, particularly under nutrient- and water-stressed conditions. Heavily affected plants often topple, with consequent total loss of bunches, while ...

Plant-parasitic nematode incidence, population densities and associated damage were determined from 153 smallholder banana and plantain gardens in Bas Congo (9 – 646 meters above sea level, m.a.s.l) and South Kivu (1043 – 2005 m.a.s.l), Democratic Republic of Congo, during 2010. Based on the freq...

Banana (Musa spp.) is a vegatatively propagated crop and the type of planting material is of great importancefor the productivity of banana plantations. Traditionally, sucker derived planting materials havebeen used to establish banana plantations but there is a risk of transmitting pests such as...

Endophytic non-pathogenic Fusarium oxysporum isolates are known to control Radopholus similis through induced resistance. Using complementary (c)DNA-amplified fragment length polymorphism (cDNA-AFLP), we identified genes induced in nematode-susceptible and -tolerant bananas following colonization...

In studying plant colonization by inoculated Fusarium oxysporum endophytes, it is important to be able to distinguish inoculated isolates from saprophytic strains. In the current study, F. oxysporum isolates were transformed with the green (GFP) and red fluorescent protein (DsRed) genes, and beno...

Pests and diseases have become major constraints to smallholder banana production in the highlands of East Africa. Biotic challenges to banana cultivation include fungi, bacteria, viruses, nematodes and insects. Host-plant resistance, developed either by conventional breeding or by application of...

We studied the effect of treating banana and plantain (Musa spp.) suckers using boiling water for the generation of healthy planting material. Small, medium and large-sized suckers of two East African highland bananas (cvs. Mbwazirume, Kibuzi, AAA-EA) and one of plantain (cv. Agbagba, AAB) were d...
