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...

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...

Beauveria bassiana (Balsamo) Vuillemin, an entomopathogenic fungus, can exist asymptomatically as an endophyte in banana (Musa spp.) and potentially provide management against the banana weevil Cosmopolites sordidus (Germar). However, in order to optimize its biological control potential when dep...

The effects of Beauveria bassiana dose and exposure duration on colonization and growth of tissue cultured banana (Musa sp.) plants
The entomopathogen Beauveria bassiana (Balsamo) Vuillemin (Ascomycota: Hypocreales) survives as an endophyte in a wide range of plants, offering substantial protection against tunneling insect pests. Although current research indicates that the fungus can live as an endophyte in tissue-cultured b...

Effect of endophytic Beauveria bassiana on populations of the banana weevil, Cosmopolites sordidus, and their damage in tissuecultured banana plants
The effect of endophytic Beauveria bassiana in banana (Musa spp.) plants against the banana weevil Cosmopolites sordidus was examined in a screenhouse study in Uganda. Tissue-cultured banana plants (cv. Kibuzi, genome group EA-AAA) were inoculated by dipping roots in a B. bassiana suspension of 1...
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...

Beauveria bassiana (balsamo) vuillemin as an endophyte in tissue 3 culture banana (Musa spp.)
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 ...

In vitro nematicidal effect of endophytic Fusarium oxysporum against Radopholus similis, Pratylenchus goodeyi and Helicotylenchus multicinctus
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...

The burrowing nematode Radopholus similis is one of the major constraints to banana (Musa spp.) production worldwide. Resource-poor farmers can potentially manage R. similis by using naturally occurring banana endophytes, such as nonpathogenic Fusarium oxysporum, that are inoculated into tissue c...
